The STT-15 is not just another AR \ M4 Receiver; it’s your final answer. Before the development of the STT-15, the only option for left-handed (South Paw) shooters was to either adapt to a right-handed platform or purchase expensive add-on accessories. It has always been difficult and frustrating to try and find the right combination of accessories to allow the weapon to be manipulated accurately, quickly, and correctly. Even with hundreds of dollars in additions, the fit and feel of the rifle were never quite right. When STT designed this receiver, we wanted it to not only accommodate left-handed shooters but to accommodate right-handed operators equally as well.

The answer was obvious; we needed a platform that would meld its operation to every shooter no matter the situation or demands, and without the addition of hundreds of dollars in additional accessories. This firearm had to be 100% out of the box. No shortcomings or required add-ons would be acceptable. STT put countless hours into combining a set of features that not only achieved those requirements but worked with the plethora of magazines, Mil-Spec components, and after-market parts available today.

San Tan Tactical will never compromise on the goal of 100% ambidextrous operation for fewer features, faster production, or cheaper materials. The STT-15 takes over twice as long to manufacture as a standard mil-spec receiver. We use the strongest American Made raw material to create your new rifle!

The STT-15 begins as a billet of 7075-T6 aerospace grade aluminum, giving us the blank canvas we needed to create the ultimate receiver.
