From the stylized receivers and EML handguards every BANSHEE is tailor-made to be the personal defense weapon you can always depend on. With full-length M-LOK slots on both sides and the bottom of the handguard as well as M-LOK between the top Picatinny rail sections you'll always have enough space for those must-have accessories.
