6.8 SCP II BCG
Specifically designed and measured by SAMMI specification for the 6.8 SPC II
Complete, mil-spec assembly with bolt, bolt carrier, and firing pin
ready to drop into the rifle or carbine upper of your choice. Features a
shot-peened bolt for increased surface strength and durability, and an
extractor booster to ensure reliable cycling during rapid semi-auto or
full-auto fire. Each assembly is magnetic particle inspection tested to
ensure its free from imperfections that can lead to premature failures.
Properly staked gas key prevents gas leakage that can lead to short
stroking. M16-style carrier on the black phosphate model has full-length
shroud for tripping auto sear, so this carrier may be installed on
full-auto law enforcement and military rifles.
