Description
This Spike's Tactical Bolt Carrier Group is the same Mil-Spec BCG that they sell but with a durable Nickel Boron coating. It is High Pressure Tested and Magnetic Particle Inspected (HPT/MPI). Nickel Boron is smoother than Hard Chrome, easier to clean, allows smoother cycling, and can run almost lube free for thousands of rounds without chipping, peeling, or flaking. Compatible with AR-15 style rifles. Made from 8620 Tool Steel (Carrier) and 158 Carpenter Steel (Bolt) with a shrouded firing pin, forged Mil-Spec gas key attached with Grade 8 hardware, and shot-peened bolt. Includes Mil-Spec Extractor Spring, black extractor insert, Viton O-Ring, and Tool Steel Extractor.
