Genetal Dynamics Next Generation Squad Rifle (NGSW) RM277 = Machine gun + rifle
The weapons use what General Dynamics’ describe as a ‘gas and recoil operated, impulse averaged, air cooled’ system. With both the rifle and AR being magazine fed from box magazines – this again is a departure away from rival designs, with both Textron and SIG Sauer both utilising belt feeds.
The suppressor appears to use their flow through design. General Dynamics note that the suppressor will last the life of the barrel it is mounted on and that the design “minimizes flash and reduces sound levels to less than the requirement”. They also confirm that their prototypes are within the US Army’s weight requirements.
The weapons use standard AR-15 compatible pistol grips with an ambidextrous safety selector positioned as in the AR-15/M16/M4. This retains some familiar features from weapons soldiers will already be familiar with, however, semi or fully-automatic selection is done by a laterally sliding selector just above the safety. The prototypes appear to have stamped aluminium upper receivers and forends with two prominent take down pins, one just in front of the pistol grip assembly and the other in the rear of the receiver. There is a 12 o’clock picatinny rail and numerous MLOK mounting points. The design moves away from the AR-15/M16’s classic T-charging handle and instead has a side-switchable charging handle located above the barrel. It is unclear if the direction of ejection can be switched, but this seems a probable feature. The AR prototype has a slick-looking bipod which is angled to attach onto the forward-angled forend and folds up quite flush with the bottom of the weapon (see photo below). There does not appear to be any means of adjusting the weapons’ length of pull.
As mentioned earlier the weapons use a ‘gas and recoil operated’ system, while General Dynamics have not gone into detail of how this works they do mention some interesting features. Publicity materials describe “shot recoil, impulse averaging technology” which minimises recoil loads and weight and enables controllable automatic fire – which is abundantly demonstrated in their promo video below. This is said to give the weapons reduced felt recoil optimal for accurate long range engagements. Perhaps the most interesting feature, however, is that the weapons use a dual firing system – firing from a closed bolt when in semi-auto and from an open bolt when in full-auto, to aid cooling.
