AR-15 Bolt Assembly

Features

1. AR-15/M16 Platform Compatibility — Drop-in replacement bolt assembly built to mil-spec dimensions for any standard AR-15 or M16 bolt carrier.
2. 9310 Steel Construction — Machined from 9310 alloy steel, the industry standard for high tensile strength and impact resistance at the bolt face and lugs.
3. Magnetic Particle Inspected — Each bolt is MPI tested to detect surface and subsurface flaws, ensuring no cracked or compromised parts leave the line.
4. Shot-Peened Lugs — Locking lugs are shot peened to relieve stress and add fatigue life, a critical step for bolts that see high round counts.
5. 5.56 NATO / .223 Rem Bolt Face — Standard .378 bolt face cut to run 5.56 NATO, .223 Remington, and .300 Blackout case-head ammunition.
6. Complete Assembly — Ships fully assembled with extractor, extractor spring, ejector, ejector spring, and roll pins — no parts to source separately.
7. Heat-Treated and Tested — Properly heat treated to mil-spec hardness for consistent lockup and reliable extraction across thousands of rounds.
8. Direct Impingement Ready — Gas rings are pre-installed and gapped, ready to drop into your carrier and head to the range.
