not 100% sure what brand they are, handguard is polymer(plastic but cool) with a metal bit at the front muzzle and barrel is full metal if you are interested or have any questions please message me on WhatsApp
functionally fine, got it in a box of bits and don't want it, i believe it is for a Glock but not 100% sure it is extremely sturdy and well built if interested msg me on WhatsApp
