LBE Unlimited ARBCASY Mil Spec AR-Platform Bolt Catch Assembly - Black Steel

The LBE Unlimited ARBCASY is a mil-spec AR-platform bolt catch assembly built to US military specifications and made right here in the USA. If you're building or maintaining an AR-15, you know that a reliable bolt catch is non-negotiable—it's what lets you lock the bolt to the rear when the magazine runs dry or when you need to field-strip. This is a straightforward, no-frills replacement or upgrade component for shooters who want proven mil-spec reliability without paying boutique prices.

LBE Unlimited specializes in hard-use AR parts, and this bolt catch assembly reflects that philosophy: it's manufactured to military specs, meaning it'll work with standard-issue rifles and any AR-15 built to the same blueprint. Whether you're an everyday shooter, a serious 3-gunner, a hunter running an AR for varmints or hog control, or an operator building a rifle exactly to spec, a mil-spec bolt catch ensures your rifle functions the way it was designed.

The assembly comes complete with everything you need to install it: the bolt catch itself, the roll pin that secures it, the spring, and the buffer detent. That means you're not hunting through parts bins or making a second order. Black steel construction stands up to training schedules and field use, and the finish resists corrosion under normal handling. Drop this into your lower receiver and you're good to go—no surprises, no modifications, just American-made reliability.
