Stripped Lower

This item is currently Out of Stock.

The STS (Short Throw Safety) AR15 Stripped Lower Receiver is the perfect lower to start your build. Custom designed markings accept short-throw safety selectors while maintaining mil-spec dimensions and correct component interface. Selector markings will work with 45, 60 or 90 degree safety selectors.

STS lowers are marked and milled to accept short-throw safety selectors, but will work with standard selectors as well!

    This is my 3rd aero lower purchased from E-Arms. He has the lowest prices and No they are not blems. Each time they assemble easily like they were a match fit part.
