The J68 is a fully ambidextrous carbine that ejects from the bottom. Unlike the J67, it is available in .40 S&W and .45 ACP in addition to 9mm Parabellum. The weapon uses Glock magazines.
The J68 features a target trigger, clam shell break open design (actuated by a lever underneath the stock), a bolt hold open device, picatinny rails, and M-LOK compatible slots.
A model of the gun is made to comply with California gun laws, featuring a "finned" grip instead of a pistol grip and a welded muzzle brake.
