TPS Arms bolt catch in black has slightly different black anodize than my other black parts in direct light. Function is correct, drops in any milspec lower with the standard spring. Cosmetic variation only - mechanical reliability is solid.
TPS Arms AR-15 bolt catch assembly in black is a solid budget bolt catch. Phosphate steel construction. Detents into both fire and retracted positions positively. Drop in fitment with the standard catch spring. Reliable basic catch.
