The AR Pistol build is complete. After a number of weeks of getting parts, I built it this morning. The mail ran and the muzzle device was there so I was able actually finish it today instead of tomorrow.
Spike’s lower and BCG
CMMG upper and LPK
BCM Gunfighter w/ medium latch
Rock River buffer tube and guts
SicTac arm brace
Ranier Arms 7.5″ 1:8 chrome lined barrel
Yankee Hill Lightweight Series mid length rail
Hogue rubber grip
Troy lopro gas block with Brownell’s gas tube
Atomic Tactical STD flash suppressor (& for those whose mind is in the gutter, STD stands for Simple Threaded Device)
Total cost? Haven’t tallied it up yet but it is over a grand since I upgraded some of the parts instead of some of the off the shelf that were less expensive.
Sorry for the late reply…been on 9 days of wonderous vacation. Anyway, to answer your question, the lower is marked as multi caliber. However, I am a big big fan of 5.56 / .223 and so to maintain the caliber commonality of the rest, that is what it is set up for. Haven’t been able to fire it yet, but that time is coming soon enough.
