Details

The San Tan Tactical STT-15 Big Bore Pillar Billet upper receiver was designed from the ground up to be lighter, stronger, and better. 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 ejection port for optimal function with .458 SOCOM and .50 Beowulf. An upper built on this receiver won’t hold you back. The STT-15 billet AR-15 upper receiver from San Tan Tactical offers uncompromising performance, so you can build the rifle you need.

Features:
  • Enlarged ejection port for .458 SOCOM and .50 Beowulf
  • Machined from 7075-T6 aluminum
  • Mil-Spec Type III hardcoat anodized black
  • Forward assist and ejection port cover factory installed
  • M1913 flat top picatinny rail
  • Lightened receiver cuts
  • Engraved T-markings

The upper receiver comes fully assembled with a dust cover and forward assist. Just throw in your favorite ambidextrous charging handle and you have a rifle that doesn’t discriminate against lefties. Where most billet receivers are typically heavy, blocky designs, San Tan Tactical utilized 3D CAD modeling software to save weight in places where extra material didn't serve any structural purpose. At just 8.2 ounces, this billet receiver comes in lighter than some slick-side receivers without sacrificing a forward assist or dust cover.

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.
