I just finished this refinish and build yesterday with a few small parts I got at the Indy 1500 gun show. I like it a lot. Lightweight compared to my decked out M4!
Barrel has a perm. mounted Bi-Lock to meet 16"
It was refinished with Norrell's Colt Grey/Black finish.
Here is one with the flash on, color looks weird to me with the flash.
