Tps Ar-15 Bolt Catch Assembly Ss

The TPS AR-15 Bolt Catch Assembly in stainless steel is a precision replacement component engineered for AR-platform rifles requiring dependable bolt-catch functionality. This assembly is designed for use in duty, competition, and training environments where consistent bolt-hold-open operation is crucial for shooter efficiency and firearm reliability.

Manufactured from corrosion-resistant stainless steel, this bolt catch assembly resists oxidation in harsh operational conditions, making it suitable for coastal deployments and humid climates. It is sized at 4 × 0.13 × 6.75 inches and weighs 0.06 lbs, ensuring compatibility with standard AR-15 platform geometry and mil-spec receiver dimensions.

This replacement part is ideal for armorers performing lower-receiver maintenance, operators building or rebuilding AR platforms, and shooters maintaining duty or training rifles. The bolt catch controls the bolt carrier group's rearward movement and locks it open on the last round, enabling faster magazine changes and immediate visual confirmation of empty-chamber status, which is essential in tactical and safety-conscious training contexts.
