Bastion Thrdd Trgr Grd 5.56 Ar Blank

The Bastion Threaded Trigger Guard 5.56 AR Blank is a precision-machined aluminum component engineered for AR-platform rifles. CNC-machined from T6 6061-aluminum and finished with hard-coat anodizing, this trigger guard replacement delivers the durability required in field conditions while maintaining dimensional accuracy critical to AR assembly standards.

The threaded design allows for direct attachment of vertical foregrips, handstops, and other modular accessories without requiring additional rails or mounting adapters. The anodized finish resists corrosion and abrasion during weapon manipulation and transition drills, while the CNC-machined tolerances ensure proper fit with standard AR lower receivers. Complete hardware package—three mounting screws and hex key—is included, eliminating the need for separate fastener sourcing. The compact profile (3 x 0.5 x 3.5 inches) and lightweight construction (0.06 lbs) add negligible weight to the platform while improving ergonomic control.

This trigger guard serves shooters building or upgrading AR carbines and rifles intended for training, sport shooting, and duty applications. The threaded interface is particularly valuable for operators who rotate between different grip configurations or who require quick adaptation to various mission profiles. Bastion's reputation for precision aluminum work in the AR accessory space makes this a straightforward upgrade path for those seeking improved ergonomics without sacrificing reliability or fit standards inherent to the platform.

Compatible with standard AR-15 and AR-10 lower receivers, the Bastion trigger guard blank integrates seamlessly into existing builds. The anodized aluminum construction balances weight savings against durability demands, making it suitable for extended training cycles and operational environments where component reliability directly impacts mission success.
