Black Rain Ordnance
Overview
The Black Rain Ordnance Bolt Catch is a durable steel component designed to securely hold the bolt in the open position after the last round has been fired, allowing for easier magazine changes. Its phosphate finish offers enhanced corrosion resistance while maintaining a sleek black appearance that fits seamlessly into any build. This bolt catch is commonly found in carbine gas system builds chambered in 5.56 NATO, making it a reliable choice for those configurations.
Black Rain Ordnance Bolt Catch ranked #19 of the 54 bolt catches builders added on GunPartPicker in August 2026. Builders have been adding it to their builds on GunPartPicker since February 2026. All time, it ranks #18 of the 95 bolt catches builders have added. Builds with this bolt catch are nearly all chambered in 5.56 NATO, mostly on mid-length gas (60%, then carbine-length 40%), and nearly all AR-15.
Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today all 4 retailers we track have it in stock. It dipped to $5.94 at Optics Planet for a stretch in August 2026, under its usual $6.57 to $7.99, so sales do come around. Buying today, the lowest price is $6.57 at Brownells, above August's low of $5.94, so a better deal may come back.

Black Rain Ordnance bolt catch works as advertised. Phosphate steel construction. Detents into both fire and retracted positions positively. Drop in fitment in any milspec lower with the standard catch spring. Reliable basic catch.
