Based on the same concept as the SCAR SC, it is still a piston-driven 5.56 NATO-caliber platform but in a more compact variant that the SCAR 16S rifle.

The overall length of the handgun, with a chrome-lined free-floating 7.5-inch barrel, is 19.75 inches, which is shorter than the SC as doesn't have a stock to remain out of SBR territory but does have a vertical rear Picatinny rail with a QD sling cup. Using the same monolithic aluminum receiver design of the SCAR family, coupled with dual ambidextrous charging handles, the weight is listed as 5.65 pounds, which is almost a pound lighter than the SC. It uses a two-position user-adjustable gas regulator, which can come in handy.
