"Seamlessly compatible with any MILSPEC AR-15 lower, these uppers offer a cost-effective way to switch between semi-auto and bolt-action configurations."
"The BC-15 bolt action style upper and rifle utilizes a convenient, rugged steel handle with an ultra-short 23 degree throw. Less moving parts means even higher accuracy! Plus the absence of cycling noise makes it a great option for precision shooters focused on their next shot. Like all of our AR-15 complete uppers, the BC-15 bolt action style upper is designed to fit seamlessly with any standard AR-15 lower. The bolt action style bolt carrier group utilizes the same T25 Torx bit for disassembly as BCA’s Gen-2 side charging handle. "
