  • STT-15 Fully Ambi Advanced Lower Receiver

San Tan Tactical designed this lower receiver out of necessity and a desire to have a true ambidextrous AR-15 \ M4 platform. Allowing it to accommodate any and all shooters without the need to add countless costly add-ons. Whether you are a right or left handed shooter, or forced to shoot with your off hand, the STT-15 has you covered! STT-15 is designed specifically for situations in which there's no room for error and you must use your rifle to take that shot!

The STT015 is machined directly from a billet of 7075-T651 aerospace grade American aluminum on brand new Haas CNC machinery. This allows the manufacturer to hold ultra-tight tolerances and make sure that the final product is exactly as designed. The finished receiver is then finished in Mil-Spec, MIL-A-8625 Type III hard anodizing.
