Our AR15 Stripped Lower Receiver w/ Geissele Super 3 Gun Trigger & Anti-Walk Pins is a great way to start your AR15 build. Made to Mil-Spec standards, our stripped lower receiver is second to none in quality and works with Mil-Spec AR15 parts & components. 

The Geissele Super 3 Gun (S3G) is a semi-automatic, hybrid cross between a single-stage trigger and a traditional 2-stage trigger. Its robust feel and light pull weight, combined with a lightning-quick reset, make this trigger ideal for any 3 Gun competitor. 

Our Stag 15 Anti-Rotation (Anti-Walk) Trigger/Hammer Pin Set is designed to withstand the high impact of full and semi-automatic fire. These pins will protect wear on your AR-15 receiver and are QPQ Finished. No modification to the receiver is required and this set will replace the current trigger/hammer pins. All hardware included for installation.
