General Dynamics OT&S was one of three companies selected to compete for the US Army’s Next Generation Squad Weapons program which will replace the M249 Squad Automatic Weapon and M4 Carbine in close combat formations with an Automatic Rifle and Carbine firing a new 6.8mm cartridge with desired performance similar to a 270 Win Short Mag.

Their solution has been under wraps, until now.

These photos, obtained by SSD, show that both the AR and Carbine are in fact, Bullpup designs. Both also feature a suppressor.

Interestingly, the AR is box fed, a requirement insisted upon by the US Marine Corps to satisfy their continued participation in the program. The AR also incorporates a longer barrel as well as a bipod.

They fire a new composite-cases cartridge in 6.8mm, designed and manufactured by True Velocity. GD O&TS is also partnered with Beretta Defense Systems.

Look for more details soon, as the system will be formerly unveiled during this week’s Association of the United States Army annual meeting.
