I say sort of build because I didn't mount the barrel. I started this last spring and just finished it last week. This would be the closest to a complete build I have ever done.
Anyway, it is a BCM mid-length with 14.5" lightweight barrel.
Fixed DD 1.5 rear sight and a Aimpoint H-1. BCM medium charging handle and colt BCG.
Stag Lower and LPK, BCM six pos. receiver, carbine buffer and a colt super stock.
I have only had it to 50 yards to zero, no problem, I plan to take it out to 200 next week. This will have a 50y/200m zero, a first for me, I have been using 25/300 previously. Happily surprised with the Stag LPK trigger, I wasn't sure what to expect. My experience with this platform has been exclusively ponies, most of them pretty well broke in.
I put this together as an HD rifle and to get some experience with a RDS.
