The Davidson Defense AR-15 Bolt Catch Roll Pin is a 3-32 x 1-2 stainless steel 420 roll pin with passivation treatment. It is sized for standard AR-15 lower receiver bolt catch fitment and is compatible with mil-spec and standard commercial AR-15 lower receivers.
The roll pin is manufactured from stainless steel 420 with a passivation treatment applied to the exterior surface. Passivation removes surface contaminants and develops a protective oxide layer that resists rust and oxidation over extended storage and use. Stainless steel 420 maintains structural integrity in humid and wet environments where standard steel hardware is more susceptible to corrosion.
The 3-32 x 1-2 dimensions are sized for standard AR-15 bolt catch fitment in mil-spec and most commercial lower receivers. This roll pin addresses the bolt catch retention point on the lower receiver as a direct-fit replacement or spare component for standard AR-15 platform builds.
The bolt catch roll pin secures the bolt catch assembly within the lower receiver. This pin is a small but necessary part of the lower receiver hardware set and is a common replacement item for builders completing or servicing AR-15 lower receivers.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Verify fitment with your specific lower receiver before use.
