SanTan Tactical STT-15L Stripped Lower Receiver OD Green

The SanTan Tactical STT-15L is a stripped AR-15 lower receiver machined from 7075 billet aluminum and finished in anodized OD Green. It is a lightweight option for builders and shooters who carry the rifle for extended periods, including 3-gun competitors and hunters, and it shares the visual identity of the brand's standard STT-15 receiver combo.

The receiver is trimmed to reduce overall weight while retaining the strength of billet aluminum construction. It is a semi-automatic, multi-caliber lower that accepts a range of AR-15 chamberings. The ambidextrous bolt release suits both right- and left-handed shooters, and bullet pictogram safety selector markings identify the safe and fire positions.

The lower fits AR-15 pattern upper receivers and is supplied as a stripped receiver, so the trigger group, buffer assembly and other components must be added by the builder.
