San Tan Tactical’s STT-15 was developed as a truly ambidextrous AR-15 lower. The STT-15 is machined from a billet of 7075-T651 aluminum and finished in Mil-Spec, MIL-A-8625 Type III hard anodizing. The STT-15 can be further customized from a selection of selector switches, take down pins, geissele triggers, butt stocks, and cerakoted finishes.
We had an original production model, and the current version is a major improvement in that they really tightened up the tolerances and improved the ambi parts. I like it…a lot.
