Introducing the Overt Industries Fighting Rifle Premium Chrome BCG

We partnered with Microbest to bring a Premium Chrome Bolt Carrier Group that is built to the specifications we demand for a hard use Fighting Rifle.
The Carrier is built from 8620 Quality Steel, Full Auto M-16 Cut, and features a full internal and external hard Chrome finish. The bolt is built from Carpenter 158 Steel, Shot Peened, and is High Pressure Tested (HPT) & Magnetic Particle Inspected (MPI).
We took it a step further and upgraded the Extractor and Ejector springs to Sprinco springs for increased reliability and performance longevity.
