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.
