The SPC10 and SPC45s are the big bore versions of our popular SPC9; designed to become your ultimate do-it-all vehicular based general-purpose carbine. The barrel lengths are optimized for the hard hitting 10mm or 45 ACP cartridges, yet are some of the lightest recoiling carbines available, thanks to B&T’s innovative and effective hydraulic buffer system and spot-on ergonomics.
