The Seekins Precision Enhanced Bolt Catch is a refined upgrade for any AR15 builder who wants smoother and more confident rifle controls. Its enlarged profile and sharply textured engagement surface make locking or releasing the bolt much easier, even when wearing gloves or working in fast paced conditions. Precision machined from strong steel and finished in a durable matte black melonite treatment, it offers long lasting reliability while maintaining a clean streamlined look on the rifle. This drop in component replaces the standard mil spec part and delivers a noticeable improvement in handling and control for both training and real world use.
