SanTan Tactical STT-15L Stripped Lower Features The SanTan Tactical STT-15L Stripped Lower Receiver carries forward the same visual identity as the brand s standard STT-15 receiver combo while trimming material to meaningfully reduce overall weight. Machined from 7075 billet aluminum the receiver maintains the strength needed for serious use while shedding ounces that add up over a long day of shooting or carrying the rifle afield. San Tan Tactical designed the STT-15L specifically with 3-gun competitors hunters and other weight conscious shooters in mind recognizing that every ounce matters when the rifle is carried for extended periods. As a multi caliber platform the lower accommodates a range of AR-15 chamberings giving builders flexibility in how they configure the completed rifle. The receiver s anodized Olive Drab Green finish gives the build a distinctive look that stands apart from standard black AR-15 lowers appealing to shooters who want their rifle to reflect a personal style. An ambidextrous bolt release accommodates both right and left handed shooters improving manipulation speed regardless of grip orientation. Bullet pictogram safety selector markings provide an intuitive easily recognized visual cue for safe and fire positions under stress. For builders who want a lightweight distinctively finished foundation for their next multi caliber AR-15 project the San Tan Tactical STT-15L Stripped Lower Receiver is available for sale at GrabAGun.
