The SC4 is an integrally suppressed carbine made by Accurafire Manufacturing Company. It was made to be a silent carbine to be used by the U.S Special Forces. It was made to correct one of the flaws of the SC3 Stealth Carbine, which was that the SC3 had only one Picatinny Rail on the top of the upper receiver; no RAS or underbarrel/side rails to mount accessories. It also does away with the folding stock, in favor of a retractable stock. It comes with MBUS sights, and ordering a CompM4 with it is optional. It also comes with a free foregrip.
-Suppressor looks heavy but is actually light, and it almost silences the sound.
