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. - A true lightweight the Bren 2 has an aluminum upper and a lower made of carbon fiber composite. 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. - Chambering : .223/5.56x45 - Magazine Capacity: 30 - Magazine Type: AR-15-M16 - Frame: Carbon Fiber-reinforced polymer - Grips: Stippled - Sights: None - Barrel: Cold hammer forged - Barrel Length: 16.5 - Weight : 7.3 lbs - Overall length: 35.6 in - Safety: Ambi manual safety
