FAQ
Is this BCG full-auto rated?
Yes — the assembly is full-auto rated and built to MIL-SPEC standards. Verify local laws before use.
Will the chrome finish flake or peel?
No — the hard chrome process used on wear surfaces produces a durable, non-porous finish. Normal wear will occur over extended service life, which is expected behavior.
Is this compatible with all AR-15 uppers?
This BCG is designed for mil-spec AR-15/M16 systems. Confirm your rifle uses standard mil-spec dimensions and headspace before installation.
How do I care for the chrome finish?
Clean with standard BCG cleaning solvents and oils; avoid abrasive tools that could score the surface. Hard chrome resists corrosion, but routine inspection and lubrication are still recommended.
