DUH..... funny

Update: We are having an issue with attempting to remove the errant trigger guard roll pin. It just ain't coming out. Even attempting to punch it out with a roll pin punch isn't working. And I don't want to force it that way any longer for fear of damaging or tearing up the dog ears/lower. Right now, they're OK.


I have taken out the opposite roll pin screw in an effort to not cause that damage as well. If I then jiggle the trigger guard back and forth, it's tight, but it does move and the roll pin moves with it (slightly). My next step is to attempt to loosen the pin with some penetrating oil (unless you think I shouldn't since it may damage the finish). I'll then try to remove it with my new roll pin pusher toll. Right now, that's not working as I can't get it to anchor properly.



At EOD, if it means I have to sacrifice the trigger guard to save the lower and its dog ears, I'm willing to do that. It's only $19.00 and it's non- FFL, so I can get another. I can't get another lower just as easily. Whatever help you can offer to help me resolve this would be greatly appreciated.





Further Update: The penetrating oil did the tricik! Just a small squirt and 15 min. later, some light taps and it came right out. I was then able to use the roll pin pusher to put in the new pin.



All is well now and the build continues. Now I'm focusing on installing the barrel, delta ring and gas tube, etc., It will be fun trying to align all the pieces of the delta ring. I guess I'll use a separate tube to ensure they stay aligned as I mount the delta ring. Then comes torquing it properly. I have the torque wrench etc, so I'll watch some more YouTube videos.


Onward! :flagwave:

Sorry I didn’t see this earlier. I was going to suggest some oil as that would not hurt the finish but, glad you were able to get it out and the new one installed. Congratulations. To be honest, I have never installed a delta ring, all mine have free float hand guards. Let us know how that goes.

Day 3 of installation complete. Delta ring and gas tube installed and aligned. I took advantage of a trick I learned on a Youtube video to re-align the delta ring etc. I should have purchased an "assist" tube to keep the item aligned, but I got them aligned and the gas tube free flowing, somehow.


I attempted to install the gas block. However, I must need to learn some things about installing roll pins.The roll pin atop the gas block that locks the tube in place doesn't fit. Too big. If I attempt to force it with a roll pin punch, it will splay out the roll pin and the punch falls through it. I checked the fit manually with the tube outside the gas block. It just doesn't fit. Taking a very small roll pin punch, I can get it through both the block holes and the gas tube holes. But way too small to hold it tight, obviously. But at least it keeps it aligned while I look at a different solution. Also, I think I'm going to have to go with the triangular HG cap because I can't get the HG on with that cap. Either that, or I may have to adjust the gas block position by a microscopic amt. (I can't move it that much or it won't align with the barrel's gas port.



I guess I'll be spending a bit of time looking for spare roll pins that fit the block as well as other roll pins.



But a little bit of progress today. I think I'll take some time off the build and play with my new RIA 1911. :D

Something is up with that pin, don’t force it as you know. It should be tight but not that tight that it deforms as you punch it in place. Good idea on buying some spares. Sometimes it’s good to revert your attention to something else so you won’t rush your build.

What’s the plan for the 1911?

Good to hear you're moving along.
It's good to take an occasional break, sit back, relax and think things through .... patience is a good thing !!


BTW ....

Ordered them on Tuesday from 'Classic' and they arrived today, via FedEx. My local Gun Shop of 40yrs/family owned is closed for the weekend to go hunting :cool:, I will pick the lowers up Monday.

Finding a site where I can test fire it for a bit. Not too much because I have to preserve my .45acp ammo. Then it will be a back up gun while my P320 remains my EDC.



I see where to by spare roll pins on Brownell's, so I'll do that as well and get back to the build. But I may practice a few roll pin pushes where possible.

A cheap digital micrometer is your friend..then you can mic pins and see the variations in what pins you have

Excellent, pig! I will get one. I hope I can also measure the holes the pins are supposed to fit in so I can gauge what size pins I need.

Thanks!

Normal micrometers only measure outside diameter, not inside like calipers can. Inside micrometers are for large holes (>1")

To measure a small hole, you'll need a small hole gauge, which you expand until it fits the hole, and then measure it with the micrometer.

Thanks much! I figured there was a trick behind it.

Sometimes you can check the hole size with a drill bit.

Or a Roll pin punch. I have one in the gas port now keeping things aligned, if not totally fastened, while I order more pins.

I've done that, and I have a 115 piece drill bit set. But if it's slightly loose the next size up won't fit, and if it's slightly too tight then then the next size down will be way too loose.

Unless it fits perfectly, it just gets you a ballpark.

I had problems replacing a firing pin on a revolver. The firing pin shaft was 1/4" exactly, but the hole was too tight for it to go in and I couldn't figure out what was going on. The drill bits didn't help and I had to take it to a gunsmith and let him deal with it. Turns out the hole was peened ever so slightly making it just barely smaller than the firing pin shaft. I mean it was sooooooo close but the firing pin just would not go in.

Update: I'm going to have to do some re-thinking. I may have to change both the hand guard and/or the gas block. Things are just not fitting properly.


The HG itself is having trouble fitting into the delta ring. I did not have this issue before when I used the Colt LE6920 OEM1. It fit perfectly. Furthermore, I think it's too long, even for the 16.1 " barrel. I'm trying to fit it on and it just isn't fitting into place. We'll see. I took the roll pin from the other gas block that didn't have the set screws and tried it. While it does fit through the block, it doesn't line up with the tube holes.


Earlier, C aleb said (in re: HG and Gas block):



I am wondering now if we could in fact, use a different low profile gas block that could fit underneath the HG front and would allow the HG to seat properly. I'd still have to worry about it fitting on the delta ring but I'll work on that. If it won't, then I may need your guidance on selecting a "free floating" HG because this MOE HG is just not working properly for this build. I'll still stick with it but at some point I'm going ot have to consider some other options.


Anyway, my spare roll pins should arrive in a week or so.

Building Confidence
 

Silly question but, is the HG an actual OEM Magpul and not a copy made for airsoft? The copies are really close to the look but the tolerances and dimensions are sometime off a little.


Sent from my iPhone using Tapatalk

Well, put it this way... it comes in a regular MAGPUL MOE box with all the appropriate markings, etc. I believe it's an actual OEM. There are no Airsoft markings anywhere or any other indications therein.


From what I can see/tell, the barrel nut may be a bit larger in diameter for the HG around which to fit. Do std. Milspec barrel nuts come in different sizes. Are some of them "Proprietary" in size? I"ll call Magpul tomorrow and get an answer to that. I might have to change out the barrel nut and delta ring. That's at one end. Then I have to worry about the other end near the gas block. The triangular HG cap does fit. But I don't know if I can get it snug with the back end. We'll see.



Let me see what Magpul has to say about the barrel nut and then we'll plan the next moves.

Post some pics of your problems.

I will. First, let me try to work with Magpul. Then we'll figure it out.

Update: Had a good conversation with Magpul this afternoon. In brief, he stated that the delta ring/barrel nut can have variations in the external diameter (at the teeth). They guarantee that if you use a "Colt" Milspec barrel nut or similar one, it will fit. The diameter from tooth to tooth can be between 1.55 - 1.56" but no more. He did state that while the internals may fit the upper, the teeth can be different. So, my mission now is to find the appropriate barrel nut and hope that it fits my current delta ring assembly. I won't mind replacing the entire assembly if needed.



He also stated that I could use a low profile gas block and the triangular HG cap with the M-LOK model of HG that I have. So we'll see what's up with that.


OK, I'll be searching for that new barrel nut and will keep you posted. I'm also awaiting shipment of my replacement gas tube roll pins, so we'll see.


I'll post pictures once I get the barrel nut issue resolved (or not).

Glad you got some insight from the manufacturer. I don’t have much experience with delta ring barrel nuts as I always go the free float route. Keep us posted!

Update: I've done some further research and I've discovered that Colt does make a "barrel nut assembly" (including the nut, ring, spring and spanner ring) rather cheep ($26.00). So I will order one of those and see how it goes. I've also been studying some Youtube videos on gas tube alignment, when I saw a handy tool to align the barrel gas port and the block hole. They sell these little push rods that you can fit into the barrel port hole, mount the block, turn it upside down and when you feel the port and block hole aligned (rod drops down into the block hole), you can then screw it down and then use a cleaning rod to break the pin so that both parts will fall out of the barrel (Make sure they do...). In a pinch, I even saw where one guy used a short span of Spaghetti to do the same thing!:D



I'll advise when the new Colt ring/assembly comes in. May be a while as I reached my spending limit for this month. :(

Mmmmm spaghetti. You are doing well Sir, keep it up.

Update. Sorry I haven't given one in a while, but I'm still waiting for a few more parts and tools. In particular a set of roll pin holders because I don't want to try the gas block pin without one. They should arrive shortly. Also, I've been a little busy elsewhere. I acquired a couple of 80% lowers (unfortunately, one of them is a "Polymer" but oh well... it came with the jig), in order to prepare for what may be coming under Biden. Also, I may very well be able to acquire a Mossberg 590a 12G tomorrow. It's not a semi-auto like the 930s I had, but it should hold me until I can scrape enough up for a JM pro, assuming prices haven't sky rocketed.


As for the build, I received the Colt built Delta Ring assembly, but I find no appreciable difference between it and the one I assembled on the barrel, except that the spring tension on the Colt is much harder/tighter. Hard to depress it. I was trying to see if I could get the HG to fit on it. What I discovered about that is that HG has a grove on both sides where I believe the teeth of the barrel nut should fit. I wish I could show you and image of it but I can't upload images directly and "Imgur" now requires a login or white list on Ad Block Plus. I think the teeth of the barrel nut go inside that grove when the HG is attached. I'll have to work on that a little. It may require a wee bit of dremmelling on the HG. It still doesn't fit perfectly. Just a little dremmeling... not much.



Oh, BTW, I figured out what happened with that first gas block I purchased... the one where I thought they hadn't supplied the set screws. In fact, they had. What they supplied were internal allen key set screws, just not the ones with the heads on them. DUH! Well, I'l l be using that first one on the build. I just have some more parts for the next build.


Anyway, I'll keep you posted. Hopefully I can finished up this build with in the month and get it ready for test firing. Then I'll be back for some suggestions on how to do that safely.


Thanks all!

Take your time and do it right, you are getting there! I haven’t done any of those 80% AR lowers but, I’ve been curious. Please let us know how that goes for ya too.


Sent from my iPhone using Tapatalk

Now you got me thinking about doing a polymer 80% lower while it's still possible to get them. President Harris will probably shut that down by executive order once sleepy Joe is out of the way.

This is the polymer 80% I got. And, as you can see, it comes with the jig and the drill bits... Still in stock as of this posting.


https://www.primaryarms.com/SSP%20Ap...0&resizew=2000
On Primary Arms Website.

Received mine today, along with the metal 80% lower as well. The polymer lower does seem rather sturdy. I'll have to see if I can mount a metal upper on it to house the action. The jig is also workable as well, but it's plastic so I don't know if it would work with a metal lower.


But the thing is, if "President Harris" also bans the sale of parts and tools to make something out of our 80% lowers, then I don''t know what we do. I guess I'll need to start buying parts now for them anyway...


And, one other acquisition today... a Mossberg 590s 12G! :lama:


It's not a full size, but it actually may work better in HD situations.

Damn! Someone else sees the nasty shit coming at us.:eek:

The American dream is alive and well... When a California call girl can get into the Whitehouse. :facepalm:

The question will be, did the old Joser die of natural causes. :rolleyes:

BTW - All my dies are RCBS. Once set up, don't touch'em. Need a new set up buy a set up kit.

Nice shotgun! I wanted a Shockwave but, now they are too much $$$$ and scarce. I’ll wait.

Sorry man.... my last set of tools arrive tomorrow, so I should be back to it shortly. I have to do the gas tube assembly very carefully.

No need to be sorry, [emoji23] I just like builds.


Sent from my iPhone using Tapatalk

Update: A wee bit of progress today. I was able to use the spare Delta ring assembly and fit it around the top portion of the HG (i.e. barrel nut teeth inside rear HG grove. So I have a little confidence in that. We'll see after I get the gas tube assembly completed, which is my next big task. With those two done, I can mount upper to lower, put on the stock, and get if finalized.



We'll see.

Checking in, how are things moving along now?

Slightly delayed, as I am currently involved in the acquisition of one of the inventory items I had lost when I had to sell it. And it's a pretty big deal for me. I was able to re-acquire a Sig Sauer P226... the first gun I ever owned. I got the exact same model I had purchased originally and, from what I understand, NIB. And for a pretty sweet price... less than what I paid for the original one! :D


This was my first purchase via GunBroker Auction, and I won the auction. It cost me $10.00 over the starting bid as some %$(@#*$% tried to out bid me by $5.00 with 2 hours left in the auction. Either they were trying to be an "Alpha Hotel..." or he was counting on me not noticing he had outbid me. He was wrong. I re-up'ed him and kept watching the auction live until it ended. I was expecting him to "15min rule" me but he did not, and the auction ended on time.


But wait... there's more. The seller wanted Paypal for payment. But what I did not realize is that Paypal had flagged the transaction as a "security risk..." Either they knew it was a "Firearms transaction" (based on the prev. history patterns of the seller), or they imposed a $500.00 daily limit on paying money, per payee. So I had to wait 24hrs to pay the balance, but it got paid, and I now have tracking info. now. I expect it to arrive at my FFL from GA on 12/09.


Next acquisition: A Mossberg 940 JM Pro. I'm trying to take care of what I absolutely need to before Biden starts clamping down. After that, I'll put in a big order for more AR15 parts as they may also become "restricted." I'll buy three sets of parts to cover the three lowers I have waiting (2 of which are 80% lowers, one of those, polymer).

I'll try to work on the current build this coming Sat. I have to align the gas block and tube, connect it onto the barrel, and then mount the HG. Then I can put it together and finish it off.


Thanks much.

Thanks much! I actually have 3 lowers (2 of which are 80% and one of those being polymer) so I will need all the other parts to go with them, eventually.

Building Confidence
 

Update: A bit of progress, today. I was able to get the HG to fit into the delta ring on the main barrel assembly. It does fit. So, now, I have to put the gas tube back in after mounting the block to the tube. I have my gas block roll pin tool and, with a little bit of lube, that may help me get it across the block and in/out of the tube. Then I have to alight the block onto the barrel hole. I have my plastic pieces for that.


I was delayed a little bit because I was involved in re-assessing my priorities in re: the election and what weapons I need to secure pronto before they get scarce from being "hogged." And I struck a huge score, over this past week.


I just completed my first successful Gunbroker auction! And it was to recover one of the items I lost when I had to sell it previously. The very first gun I ever owned.... a Sig Sauer P226 Nitron. The exact same make and model I owned previously but NIB. I think I was successful because I watched the auction very carefully. It all comes down to the last 15 minutes of the auction.


I made the first (prelim) bid at the minimum bid price, roughly 1.5 days before the auction ended. I kept watching and there was no activity at all, until maybe 2 hrs before the auction was to end. Then someone outbid me by $5.00. But, thankfully, I was watching it directly and saw the bid. I was able to counter the bid by another $5.00. And that was the last bid put on the item when the auction closed. I won the auction! :lama:


After that, it was just arranging things with the merchant, who was very pleasant and helped me when Paypal wanted to screw me by not letting me send the entire price in one transaction. I had to do it in two transactions, one 24hrs later than the first ($500.00 limit per day). This worked, and the merchant shipped within 3 days. My FFL received the pkg today!



One thing to be aware of when using GB is the "15 minute rule..." also known as the "Going... Going... Gone" rule. It's used to discourage "sniping" (ie. someone out bidding someone else at the last minute with only a short time left in the auction). If a new bid is received with less than 15 minutes left in the auction, the closing time is extended by 15 minutes past the time that last bid was received, giving the other bidders time to counter. So, say the auction originally ends at 19:00hrs, and at 18:55, someone puts in another bid, the ending time is extended to 19:10. If I then counter that last bid at 19:05, then it's extended to 19:20. If no other bids are submitted, then the auction ends at 19:20 and the last bid wins.



I'll go to pick up my P226 on Monday. Once picked up, I'm going to send my P320 into Sig Sauer for that "voluntary upgrade." THen I'll work with my FFL to figure out how we're going to manage my purchases. He actually still has some things I could get from him, still in his inventory. But I'd rather hold off on those (I pretty much know he'll still have them) and finish up with the other things I need to get on the open market.



I'll try to work on the gas tube assembly this coming week. I'll keep you posted. Winning that auction was a big deal. Now I feel confident I can get other things on GB, as long as I vet the merchant.



Thanks all!
