Built on a stripped lower. The upper is BCM with a 15" KMR-A and a cold hammer forged barrel.

I had done that at first, but a local store had gotten to the point of almost giving M4's away, couldnt not take them up on it.

It's actually an m4-2000, but I do also have an SDN-6 on my .300 blk gun.

Thanks! Seemed like a fun place to hang for a while.
