A freind of mine bought a box of gun related parts and ammo and in the box was two M-41 muzzle brakes. one blued and one in brushed nickle. He has no use for them and wants to sell them, can anyone give me a ballpark value? The blued one has wear on the high edges and is dirty, the brushed nickel just looks dirty.
