San Tan Tactical STT-15L Lite PILLAR Billet Receiver Combo - STT-15L-Lite-PILLAR-Combo

The San Tan Tactical STT-15 Lite Pillar Billet Receiver Set was designed from the ground up to be exceptionally lightweight without making any compromises. Each receiver set is precisely machined out of a solid block of 7075-T6 aluminum on state-of-the-art CNC machinery. This allows for a greater degree of precision for extremely tight tolerances and additional features like lightening cuts to reduce weight and an enlarged magazine well and trigger guard. The STT-15L billet AR-15 receiver set from San Tan Tactical offers uncompromising performance, so you can build the rifle you need. Features: Machined from 7075-T6 aluminum Mil-Spec Type III hardcoat anodized black 3D CAD Designed for maximum weight savings Threaded bolt catch pin Compatible with Mil-Spec parts kits .154” trigger pin holes Lightened receiver cuts Enlarged trigger guard and beveled magazine well Receiver tension screw Upper receiver comes assembled Matched set weighs 14.6 Oz The lower receiver makes assembly easy thanks to the limination of roll pins, but a lower parts kit is still required to finish it. Compatible with all Mil-Spec components like a trigger with .154” pin diameters and ambidextrous safety selectors. However, the upper receiver comes fully assembled with a dust cover, eliminating the forward assist to further improve weight savings. An additional feature of this AR-15 billet receiver set is built in receiver tension screw that can be accessed through the bottom near the pistol grip. San Tan Tactical believes in carrying on the tradition of American designed and made firearms and that is exactly what they are doing. Their receivers and lower parts are some of the most innovative in the industry and they are proud bring you a product not only made from American sourced materials, but American machinery as well. They take the time to listen to customers critiques and are constantly evolving their products to satisfy your needs.
