The idea behind this build was for a fighting/2A purpose carbine that would still be handy with my (still in jail) Silencerco Omega attached. I originally had a PSA 12" CHF FN upper set aside for this project. The thing is, I really hate gov't profile barrels. I am a big fan of lightweight barrels for most rifles for their weight and handling qualities, and I particularly wanted to avoid a needlessly muzzle-heavy setup for a rifle that will already have a can hanging off it most of the time. I thought about a BCM upper with the 11.5" ELW barrel, which is pretty much exactly what I like as far as barrel profile, but then I heard about Faxon's new 11.5" middy Big Gunner barrel. I had previously bought a 16" middy Gunner barrel from them, and was very impressed with the quality. Black River Tactical ran a Halloween sale on them for $149, and it sealed the deal.
I put the Faxon barrel on an Aero Precision upper with a SLR Sentry 6 adjustable gas block under a BCM KMR-A 10" handguard. My SBR lower is a PSA with an Anderson LPK, Black Rain trigger, and PSA stock kit with 7075 receiver extension, H2 buffer, and ACS-L stock and PSA overmolded grip. I added a KAC 2-600 rear sight, MBUS Gen 2 front sight, and Aimpoint Comp M4. The only thing it lacks is the muzzle device -- I ordered a bunch of Silencerco suppressor mounts for this and several other rifles from L.A. Police Gear back in September, and it turned out they are on back order. Still no word on when they might have them. I'm getting real close to canceling that order and going through somebody else. The only thing keeping me from it is that I don't really need them until the can gets here. Anyway, I just put an A2 FH from the parts bin on it for the time being.
Well, I definitely met my goal of making this thing light and handy. It weighs right at 7 lbs. unloaded, with optics. Between the lightweight barrel and handguard, the front end is ridiculously light and maneuverable. Noticeably better than the 12" PSA upper I was originally going to use. It balances toward the rear of the mag well. The Omega suppressor I have on the way is light enough that this will still be a very handy setup suppressed, and should be about the same length as a regular 16" carbine. Exactly what I wanted.
This barrel has a 0.110" gas port. It is designed to be run with an adjustable gas block. I am looking forward to getting to the range and getting it all tuned. I really like the SLR gas block and its click adjustments. It will make it very easy to go from suppressed to unsuppressed settings.
