What sets this BANSHEE apart is the Mk17 platform lower which is designed to use Sig Sauer P320/M17/M18 pattern magazines. Being able to use handgun magazines in a pistol caliber carbine or personal defense weapon allows shooters to use their existing collection of magazines, mag pouches, and other accessories.Available in a range of cerakote finishes, the BANSHEE series represents the most innovative AR pistols and SBRs available today. From the quick deploying RIPBRACE, to the stylized receivers and EML handguards, every BANSHEE is tailor-made to be the personal defense weapon you can always depend on. New EML4 handguards feature M-LOK slots at 3, 6, & 9 o'clock positions and a full length picatinny top rail for accessories as well as an integrated handstop.
