M16A4 Free Float ?'s

**mykdee** · 10-16-18, 18:10

So I have a FN & a Aero M16A4, the FN has a KAC RAS M5 rail on it and I was about to put another one on my Aero but I thought about using a free float rail instead. Just wanted some pics of some A4's with free float rails, I want to keep the FSB so pics with front sight only please. Also feedback on accuracy with free float vs KAC RAS M5.
Thanks
Mike

While I dont have an M16 I have a Colt with the fixed front sight. I am using a Troy Charlie free float rail that uses the deta ring and goes around the A2 sight.
It's a bit on the heavy side but works well , when I was looking to swap out the rail I found 3 choices.
Troy Charlie
Daniels Defense (too expensive)
Midwest (out of stock at the time)

The BCM QRF rail (The picatinny one) can also be used. Mr. Guns n Gear has a video on the install.

Anyone have pics of a free float rail installed on a A4? I searched and can not find any pics.

This one has an A.R.M.S.® #59™M S.I.R.® System (NSN 1005-01-574-2540). This is the military version as compared to the commercial version Stickman is showing. It does require the removal of the Delta ring assembly, but still utilizes the standard barrel nut.

That is one bada*% rifle, but that rail probably costs more than my whole rifle! More than I can spend. But, thanks for the pic.

Oddly enough, I have the mil one sitting around as well. I also have the ARMS MK12 extended rail sitting in plastic. I have a pretty good amount of strange things.

Build one, you won't regret it!!

Just wanted to say I love your rifle, it puts my A2 to shame in the coolness factor.
