Based on the select-fire Bren 2, this handy rifle operates via a short-stroke gas piston system with a return spring contained within the action itself. Without the need for a buffer tube, it features a folding, adjustable stock. At 35.6 inches long, folding that stock brings its length down to just 28 inches making it much easier to transport or store. The 'Ms' designation means that it employs a modular forend that can be swapped to different lengths or styles based on user preference/need. Its non-reciprocating charging handle stays stowed in the forward position until it is needed and is swappable from side to side. An AR-style bolt catch/release system is mirrored on both sides of the firearm, as well as a catch/release nestled into the front of the trigger guard. The magazine release and safety are also ambidextrous.
