TPS Arms AR-15 Bolt Catch Assembly – Stainless Steel

The TPS Arms AR-15 Bolt Catch Assembly is a direct replacement for worn or damaged factory bolt catches on AR-15 and compatible platforms. This assembly includes the bolt catch lever, plunger, and spring—everything needed to restore reliable last-round bolt hold-open function. Constructed from corrosion-resistant stainless steel, it's built for shooters who want dependable performance in humid or adverse conditions.

This is a drop-in replacement part that installs using standard AR-15 armorer's tools. The stainless steel construction offers superior corrosion resistance compared to standard mil-spec finishes, making it a solid choice for builds that see regular outdoor use or storage in humid environments. The machined lever surface provides positive engagement with the bolt carrier without excess play.
