The ArmaLite SUPER SASS (Semi Automatic Sniper System) was developed by ArmaLite Inc. and submitted as an entry for the XM110 competition, which was announced by the military in November of 2004.

Although ArmaLite’s entry was not selected by the military, the company continued development and introduced what it calls the Super SASS in .308 Winchester at the 2006 SHOT Show for commercial sales. As to be expected, this new model is based upon ArmaLite’s well-known AR-10 action.
