The SuperSASS is the ultimate tactical rifle system on the market. The SuperSASS (Semi-Automatic Sniper System) was originally designed for use by the US Military but a civilian model is available to discerning shooters who demand superb accuracy. It has a quad railed free float handguard, a fully adjustable stock and an adjustable gas system built to accommodate suppressed and un-suppressed fire. The Armalite AR-10 SuperSASS is the ultimate suppressor capable, long range rifle system. Innovations include the adjustable gas system to optimize rifle function with or without a suppressor, as well as the AR design enhancements standard on every Armalite AR-10.
