The Angstadt Arms .223/5.56 bolt carrier group is built to the exacting standards you'd find in duty weapons for law enforcement and military personnel—but available for your own AR-15 build. This is the component that cycles your rounds and anchors your action, so cutting corners here means risking reliability when it matters. Angstadt machines their carrier and bolt from premium materials (8620 alloy steel carrier, Carpenter 158 tool steel bolt) and finishes it in a durable black nitride coating that resists corrosion and wear while maintaining a clean, professional appearance.
Every unit ships having already passed high pressure testing (HPT) and magnetic particle inspection (MPI)—factory checks that catch hidden defects before the BCG reaches your hands. The carrier itself is shot peened for strength, features the M16-cut design for full-auto compatibility, and wears a properly staked gas key held down with grade 8 fasteners that won't loosen under sustained firing. Forward assist serrations on the carrier give your charging handle purchase and control.
If you're assembling a reliable 5.56 or .223 rifle for hunting, competition, home defense, or the range, this BCG handles the job without fanfare or failure. It's the kind of part that disappears into your build and just works—exactly what you want from the heart of your action.

Yes. The Angstadt Arms BCG is machined to mil-spec dimensions, so it's compatible with any standard AR-15 platform chambered in .223 Remington or 5.56 NATO.
Black nitride (QPQ) is a surface treatment that improves corrosion resistance and wear characteristics. It protects the steel underneath from oxidation and extends the life of the BCG under heavy use. It also gives the carrier a clean, professional dark finish.
Yes. Every unit is high pressure tested (HPT) and magnetic particle inspected (MPI) to detect any hidden material defects before it leaves the factory.
The M16-cut refers to the full-auto carrier design, which is the standard mil-spec configuration. This BCG is compatible with both semi-auto and full-auto uppers, though in a semi-auto rifle the function remains semi-automatic unless the upper is also full-auto capable.
