ODIN Works Pistol Buffer Tube Back Plate Blue. The smooth ultra-black finish gives an appearance of an ODIN Works part while still being tough enough to withstand hard use. The included screws securely fasten to the receiver and prevent any chance of losing a small part such as a bolt scraper spring or heat-shield. If the plate is somehow lost during installation the included flat screws provide for easy replacement.
