For sale is a complete .300 blk upper group as assembled by me.
BCM upper receiver
BCM 9” Enhanced Fluted .300 blk barrel
BCM BCG and mod 4 gunfighter charging handle
BCM low profile gas block and gas tube (set screw and dimple install)
KAC URX3 8” rail with panel kit
KAC front and rear BUIS
Surefire sfmb-762 muzzle brake
Upper has just over 100 rounds on it. Per BCM recommendation the crane o-ring was installed in the bolt after I experienced a few failures to extract during the first 20 rounds. There were no subsequent stoppages with either subsonic or supersonic ammo. The host lower was equipped with an A5H2 buffer and Sprinco green spring.
As a free bonus I’m including the KAC barrel nut wrench needed for the URX3 rail barrel nuts.
Asking $1300 shipped, payment via usps money order.
