It's really not too hard to do. The sight tower is just kept in place with taper pins. Brownell's sells a polymer block that's supposed to make it easier to drive them out.

Do you plan to install a low profile gas block, cut off the site tower above the gas block to make it low profile, or re-install the sight tower after the quad rail's installed?

All that's likely needed is:

Remove the existing 2-piece hand guards
remove the muzzle device (hope it's not pinned)
drive out the site tower pins to slide it off
unscrew the barrel nut.

There's no real reason to remove the gas tube from the gas block if you'll be putting it right back on. By D-Ring, are you referring to the sling mount?

There are also options like the Daniel Defense Omega that don't require any changes to be made to the rifle. I don't have any experience with them....I've just read some info.

By D-Ring I'm talking about the Delta Ring that holds the standard 2 piece hand guards in place. (you have to push down on the delta ring to install or uninstall the 2 piece hand guards). The Delta ring is the barrel nut I believe in my case.


I have watched videos and read about the Daniel Defense and other systems that are basically drop in "free float" quad rail systems but I am looking to do a true free floating quad rail. I believe you pretty much just take the existing
Delta Ring / barrel nut and replace the existing barrel nut with a threaded one then the true free float one piece hand guards are actually screwed/turned (threaded) in place. Then you reinstall the Gas Block / front sight post in my case. I think that the front fixed sight post is the gas block on my rifle. But I might go with a low profile gas block that has the picatinny rail on it so I can mount flip up BUIS. Something similar to this =



O yea and my barrel is threaded so my compensator / flash hider is not pinned in, so that's one good thing.

All in all I think it will be pretty simple to do just as long as I get the right tools to do the job. I have looked into that polymer tool that helps you tap out the pins that are holding the front sight post on (That might come in handy) I have some punches that I think will do the job. I replaced my stock Trigger guard with a MagPul advanced trigger guard and the punch looks similar in size to the front sight post but I can get punches easily. I do need to get a barrel nut wrench tool (whatever it's called ).

At this point I am making it sound way harder than it probably is I just need to get the parts and just do it. I have watched so many videos of how to do this that I am sure I can get the job done.

Here is a link to a quick YouTube video that shows a guy from MidwayUSA installing a FF tube =


That is pretty much what I am looking to do but instead of a plain tube style hand guard I will be installing a quad rail. There are some many different brands out there now and some are different when it comes to installing them.

Anyways now I might just be confusing people, so that's about it.

-Remove 2 piece hand guards.
-Remove compensator / Flash hider.
-Remove pins holding the front sight post in place
-Remove front sight post.
-Remove Delta ring. With AR tool or barrel nut wrench.?

-Install new threaded barrel nut. This is what my new FF hand guard will screw & lock on to.
-Install new one piece FF hand guard.
-Reinstall / slide the front sight post back in place (if I don't install a new Low profile gas block) and put the pins back in.
-Reinstall the compensator / Flash hider.

I think that is the most of it in a nut shell. Some of that installation depends on which free float quad rail I go with, some have a different style barrel nut that I would have to use...etc and if I wanted to install the Low Profile gas block with the picatinny rails on top I would pretty much just install that instead of the old A2 style sight post.

Well I might Start ordering this stuff now. You have me thinking of my AR again. A couple of the LGS around KC have some nice FF quad rails but it might be cheaper if I order them. Plus I need to get a couple of those tools.

I will keep you posted, and I might even ask you some questions sorry this was such a long post.

Thanks,
