Description

APOC Armory BCG’s with Bolts made from heavy duty 9310 Alloy Steel and Bolt Carriers from 8620 case-hardening aircraft grade steel. 9310 steel has a high core strength rating, high fatigue strength, and a high harden-ability rating overall, which makes it about 7% stronger than Carpenter 158 steel, when treated properly. The Carrier is made out of 8620 Steel, which is is what you typically find in military aircraft. This is a BCG made out of the highest quality components, and won’t break the bank, which is why it is perfect for your next 6.8SPC/.224 Valkyrie build.
