The disclosure is directed at a blank fire bullet trap attachment (BFBTA) that provides improved protection for firearm users when live ammunition is accidently loaded into the firearm. The BFBTA includes a barrel portion made of a first metal; and a hardened element portion made of a second metal, the hardened element portion sized to frictionally fit within the pipe portion; wherein the first metal is softer than the second metal, such that when live ammunition contacts the hardened element portion, the hardened element portion slides within the barrel portion.
