Sons of Liberty Gun Works SOLGW 5.56mm/.300 AAC Blackout Bolt Carrier Group

Anyone who knows us, knows our BCG’s. We test fire every unit in full auto after inspection, to guarantee our customer receives an efficient BCG they can trust for life. We HP/MPI inspect every bolt individually, upgrade the extractor spring with a Sprinco enhanced 5-coil spring, and deeply stake the gas key once it’s torqued with Grade 8 fasteners. In addition to our standard BCG’s we also offer a Chrome option, as well as special edition BCG’s assembled with O.C.K.S. fasteners in place of Grade 8. These optimized screws hold the staking on the gas key even more deeply, further minimizing the possibility of the gas key loosening. Beyond our standard caliber BCG (5.56mm/.300BLK/6mm MAX), we also offer BCG’s for .308 Winchester, 6.5 Creedmoor, 6.5 Grendel, and 6mmARC Specifications for Sons of Liberty Gun Works SOLGW 5.56mm/.300 AAC Blackout Bolt Carrier Group: Manufacturer: Sons of Liberty Gun Works Color: Black Fabric/Material: Steel Cartridge: 5.56x45mm NATO, .300 AAC Blackout Gun Make: AR Platform Gun Model: AR-15 Hand: Right Condition: New Features of Sons of Liberty Gun Works SOLGW 5.56mm/.300 AAC Blackout Bolt Carrier Group: Carpenter 158 HP/MPI bolt 8620 Carrier 4340 tool steel extractor Sprinco 5 coil spring Chrome lined carrier and gas key Phosphate finish (standard model) Full Auto Test Fired Lifetime Warrantied Package Contents: Sons of Liberty Gun Works SOLGW 5.56mm/.300 AAC Blackout Bolt Carrier Group
