  • Information
The SI Defense threaded bolt catch screw is made of stainless steel. Designed for use with SI Defense AR-15 and LR-308 lower receivers. It is an improvement over the roll pins in standard lower receivers, and is easier to install. This will not work with other lower receiver brands unless the bolt catch roll pin tunnel is tapped with a 6-32 thread pitch.
