The LaRue Tactical LT15LTBCG556STD Texas Spec Bolt Carrier Group delivers precision-machined reliability for AR-15 platforms in 5.56/.223 calibers. This full-auto rated BCG incorporates LaRue's exacting manufacturing standards to ensure consistent cycling and enhanced durability over standard mil-spec components.
What Makes This Different
LaRue's Texas Spec designation indicates tighter manufacturing tolerances than standard mil-spec bolt carrier groups. The carrier features a properly staked gas key with Grade 8 fasteners, while the bolt undergoes magnetic particle inspection to detect stress fractures before they become failures. Shot-peened surfaces increase fatigue resistance, extending service life beyond conventional BCGs.
Key Features
- Full-auto rated bolt carrier group for enhanced reliability and heat dissipation
- 8620 steel bolt with proper headspace and timing verification
- Carpenter 158 steel bolt with magnetic particle inspection
- Shot-peened bolt and carrier surfaces for increased fatigue resistance
- Properly staked gas key with Grade 8 fasteners and thread locker
- Chrome-lined interior surfaces for corrosion resistance
- Compatible with standard AR-15 upper receivers in 5.56/.223
Field performance demonstrates consistent extraction and ejection across various ammunition weights and environmental conditions. The full-auto carrier mass provides reliable cycling with both lightweight and heavy projectiles, making it suitable for competition shooting, training applications, and duty use. Chrome-lined surfaces resist fouling buildup and simplify maintenance procedures.
