Update: The gas block arrived today.

Good news - It fits well over the barrel. And having measured it, I will definitely need the mid-length HG.


Bad - News - The shipment arrived with missing parts (allen key and the two set screws were missing). And, apparently, Optics Planet is not taking phone calls right now. Customer returns are also delayed.

Better news - After speaking with both Optics Planet and the manufacturer GunTech, Both have indicated they are willing to supply the missing allen key and set screws. Could be a week to receive them.


So, again, we'll see what happens.

I’m glad you’re making progress on the build.

If the gas block is steel, then it should work well. If it’s aluminum, then don’t expect it to last long term.

That, and there is this Little crow Gunsmith Roll pin pusher that seems to do very well.


Here is a youtube video on it (I wish I recall how to embed them in these posts like you did).

Great tool, might just have to add it to my box. Thanks.

I had to order some peel washers to make sure the brake is clocked properly. So, my upper build is on hold till I receive those washers.

Is that something I need to worry about?

Not really. It all depends on the flash hider or brake. Usually the crush washer that comes with it is sufficient enough to align the muzzle device correctly. If you want to just buy some peel washers to be on the safe side, I only paid like $7 for a pack of 5.

I agree .... that does look to work quite well. http://www.cotep.org/forum/images/icons/icon14.gif

Update: All remaining parts for the build (and most of the tools) now ordered from Primary Arms. This, including the Vice blocks, barrel wrench, and the remaining items. The vice itself and the torque wrenches were ordered from Amazon. Also an update on the gas block. Optics Planet agreed to ship a replacement item without me returning the item that had missing parts. Nice folks!


And in a real twist of Irony, I discovered that Optics Planet HQ building is 3150 Commercial Avenue in Northbrook, Ill. I actually used to work just down the street from them at 4000 Commercial Ave, although the company I worked for is not there any longer. It was 1981 - 1983, so......


Anyway, we're moving right along. I think I have roll pin punches already, but I'll have to check my kit. If not, I'll get them, along with the hammers, and that roll pin pushing tool (see above).


I'll keep y'all posted when I start the build. But I think I may need to look at a couple of "Insurance pieces" (ie. replace my 1911 and my .22) before the election just in case Biden does win.... But we'll see.


Thanks all.

Awesome! Can’t wait to see your build come together!
