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,

Ah, D-Ring = Delta Ring assembly. Sorry, my bad.

Yep, you definitely have all the needed info. All that's left is to do it.

My complete 223 rifle was built during the ban period, which I believe is why it was so neutered. Although it's got a 16" barrel, the compensator is actually pinned/welded in place. Instead of taking it somewhere to have them remove the pin, I just bought a Yankee Hill drop in two piece quad rail.

If it weren't an under 1 MOA barrel (without being free floated) with my handloads, I would have scrapped it years ago.

Since the new week has started, I guess I'll order an LPK now. .................Done!

Does your AR have a rifle or carbine gas system?

I ordered a Mega forged lower receiver yesterday. The only dealer I could find that had inventory and didn't require a money order was T&A Armory out of CA.

Jason Steele sent them his FFL information last night.

I should have a complete rifle within a couple weeks.

I picked up the lower receiver from Jason today. He says lots of people have been buying stripped lowers through him lately.

The lower parts kit is supposed to arrive on Tuesday, so I'll take it to the range next weekend.

Very nice can't wait to see it. I am sure you can't wait to have it completed.

Sorry I never replied to your last response to me, I have been busy this week but I did break down and made some upgrades To my AR. I went with the Daniel Defense Omega Quad rail and I dropped the money on a new EoTech 3x Magnifier. I went to the range today, not the best day it was HOT out there but the M4 shot excellent. I rezeroed my EoTech and the new expensive magnifier but I tell you the setup is excellent.
There are some things I need to upgrade still and add but it's getting there.

I will post a couple pics in a few.


Congrats on your build. I may have to build up a 6.8 upper once I'm done with my current setup.

I was at the Parma range this morning also, until a little after 11. I put another 25 rounds through the 6.8 upper and tried the modified op rod in the M1.

I saw your comment in the CBOB for sale thread, and figured you bought a free float rail of some kind. Wasn't quite expecting the 3X magnifier. What mount did you choose?

You should definitely post some pics.
