LANTAC USA Bolt Catch Pro AR-15 17-4 PH Stainless Steel QPQ Black

The LANTAC USA Bolt Catch Pro is a premium drop-in upgrade for the AR-15 platform, designed as a direct replacement for the standard Mil-Spec bolt catch. It is precision CNC machined from 17-4 PH (Precipitation Hardened) stainless steel in H900 condition, giving it far greater strength and wear resistance than the factory unit. The part is finished in a corrosion-resistant QPQ (Quench Polish Quench) Nitride coating that produces a deep, uniform black surface, well matched to nitrided and black-anodized lower receivers.

The Bolt Catch Pro is engineered to function reliably with standard Mil-Spec forged lower receivers as well as LANTAC's Raven and Onyx lowers, making it a versatile upgrade for builders and end users alike. An aggressive grip texture on the actuator pad provides positive engagement with the firing hand, allowing the shooter to lock the bolt to the rear or release it without fumbling, even with gloves or in adverse conditions. The drop-in design installs using the existing bolt catch roll pin and spring, requiring no additional machining or modification.

Whether you are building a duty, defensive, or competition AR-15 and want a more robust and tactile bolt catch than the factory part, the LANTAC Bolt Catch Pro delivers the materials, finish, and ergonomics expected from a premium small-part upgrade.
