SanTan Tactical STT-15 Pillar Lower/Upper Receiver Set OD Green Multi-Cal

The SanTan Tactical STT-15 Pillar is a billet aluminum lower and upper receiver set for AR-15 platform semi-automatic rifles. It is designed for builders who want true ambidextrous operation, with ambidextrous controls including the bolt release included in the set, so left- and right-handed shooters can use the same manual of arms without aftermarket parts.

The receivers are machined from 7075 aluminum and finished in Olive Drab Green anodizing. The set accepts multiple AR-15 caliber configurations, so builders can match the cartridge and upper to the intended use, from home defense carbines to range rifles.

The set is sold as a bundle of lower and upper receivers.
