Bolt Catch Plunger

AR bolt catch plunger. Machined from steel, Made in the USA

If you are assembling your new AR 15 or AR .308 lower receiver or installing an extended bolt catch, it will require a bolt catch plunger that goes between the spring and the bolt catch. This bolt catch plunger is fully machined in-house at Phoenix Weaponry from mild U.S. steel. A black oxide coating is then applied for great durability and long life.
