The rifle features a Kinetic Development Group MREX MKII M-LOK handguard that extends forward of the gas block, giving the shooter additional rail space and a slimmer profile for accessories and grip placement.
A Primary Weapons Systems FSC multi-port muzzle brake is factory-installed, helping to mitigate recoil and muzzle rise while maintaining quick follow-up shots on the 7.62 NATO platform.
The 16.25-inch cold-hammer-forged, chrome-lined barrel with a 1:12 right-hand twist pairs with the SCAR’s proven short-stroke gas piston operating system for reliable cycling in varied conditions.
The polymer stock telescopes for length of pull, folds to the side for compact storage, and includes an adjustable cheekpiece, bringing the overall length down to approximately 28.5 inches when folded.
Additional touches include a nickel-Teflon coated trigger for a smooth pull, a reciprocating charging handle from the earlier SCAR generation, and folding polymer sights that ride on the numbered 0-39 Picatinny top rail.
