Troy Industries Troy Gas Block - .936

The Troy Industries Troy Gas Block – .936 is a low-profile gas block engineered for bull barrel rifles that feature a 0.936-inch gas block seat. This precision-machined component enables operators to transition from fixed front sight gas block configurations to modern free-float rail systems without sacrificing reliability. Compatible with .223/5.56 NATO and .308 Winchester bull barrels, the .936 gas block provides a modular upgrade path for shooters who demand accessory rail coverage without replacing the entire upper receiver.

Constructed from 4140 pre-hardened steel and finished with MIL-STD Manganese Phosphate, this gas block delivers the corrosion resistance and durability required for field duty and training applications. The Manganese Phosphate finish provides robust protection against moisture and environmental degradation while maintaining a professional tactical appearance. Weighing just 0.15 pounds, the low-profile design minimizes sight-line obstruction and allows unobstructed mounting of your chosen handguard system over the gas block. Note that the gas tube roll pin is sold separately.

This component is ideal for shooters upgrading precision rifle builds, law enforcement duty rifles, or civilian training platforms where barrel profile and rail compatibility are design priorities. Whether you're refurbishing a legacy bull barrel upper or building from the ground up, the Troy .936 gas block bridges older barrel specifications with contemporary accessory standards. Operators replacing factory-pinned gas blocks will appreciate the modular flexibility and straightforward installation that allows quick transition to rail systems without permanent modifications.

The .936 bore diameter is a specific requirement—verify your barrel's gas block seat before ordering. Troy Industries' reputation for precision machining and mil-spec compliance makes this component a reliable choice for tactical platforms where compatibility and durability are non-negotiable.
