The San Tan Tactical STT-15 Pillar ambidextrous lower receiver in OD Green (brand part no. STT15-LOWER-ANO-OD) was born out of a desire to build a true ambidextrous AR-15/M4 platform, letting right- and left-handed shooters, or a shooter forced onto their off hand, run the rifle without adding costly aftermarket controls. San Tan Tactical machines the full suite of ambidextrous controls directly into the STT-15, so there’s nothing extra to bolt on to get symmetrical manipulation. This lower ships stripped in an OD Green finish, ready for the builder’s own lower parts kit, buffer, and stock. Among the lowers in the AR15 lowers category, the STT-15 Pillar stands out for its built-in ambidextrous design.
