Bolt Catch Screw and Allen Wrench Key (hex key)

One of the reasons we chose the DPMS Generation 1 pattern for our AR15, AR9, and AR-308 platform is for the ease in which you can install and change your bolt catch. Gone are the days of having to punch in and out a small roll pin, with the set screw you can swap install or swap a bolt catch in seconds without any worry of scratching your receiver! Purchase this with any lower to make finishing your build a breeze.

What is a bolt catch?

The bolt catch is what will lock your bolt-carrier group (BCG) to the rear once you run out of ammunition to facilitate reloading. A bolt catch is also useful for clearing malfunctions and showing that the chamber is empty.
