MK-17 CSASS (Patent Pending Rifle Design)

The MK-17 Compact Semi-Auto Sniper System (CSASS) has been purpose built to serve as the ultimate compact sniper system. SWORD started with an AR-10 design familiar to US and coalition troops. Replacing the gas impingement operating system with our proprietary and robust short stroke piston system gave the rifle reliability and durability, while eliminating fouling and carbon build up. We chose a  16″ Barrel with a 1:7.5 twist rate to give the rifle the weight and feel of a 5.56 carbine, with the enhanced ballistics of 7.62 NATO. The Mk-17 utilizes a free-floating forend system with MLOK compatible slots at the 3, 6, and 9 o’clock positions along with a full length picatinny at the 12, this allows the end user to adapt attachments to the rifle for modularity on the battlefield. We upgraded the traditional AR style rear charging handle with a non reciprocating side charging handle that eliminates negatives such as charging handle impingement malfunctions and blow back in the operators face during suppressed operation. The rifles’ ergonomics make weapon manipulation easy and intuitive due to its ambidextrous bolt catch/release control design, located outside the trigger well and built into the rifle it allows the operator to maintain fire control while using the same lever for catch and release. The MK-17 CSASS is available as a stand alone rifle or as a complete weapons system which includes suppressor, bi-pod, sling and optic. Employment of this rifle system gives the end user a lighter weight, more accurate, and reliable answer to the compact sniper system requirement.
