Thin, anti-snag profile and textured surface still allows for traditional manipulation of the bolt catch while maintaining unobstructed access to the trigger Easy attachment to the existing bolt catch paddle via one screw. Machined from durable billet 6061-T6 aluminum with mil-spec finishing. MIL-A-8625F, Type III, Class 2 hard anodizing with manganese phosphate on the screw per MIL-DTL-16232G.
