AR-15 16" Flat Top Rifle kit with M-4 Feed ramps.

16" Rifle kit with HBAR Barrel with M-4 Feed Ramps.

We had some of these come in and are available now with some options.  These have the M-4 cut feed ramps in the A-3 Flat top config.  Feed ramp cuts in both the barrel extension and the upper receiver for increased feeding reliability.  We only have these in A-3 Flat top.
