The Proto 1 Piece Barrel is precision honed to a .690 micron tolerance. These barrels go through a five step honing and quality control process to ensure every one is as precise as Proto designed them to be. Made from aircraft grade quality 6061 T6 Aluminum for the perfect balance of weight and strength. Hard anodized color to match your style and also add a protective layer to your barrel for durability from scratches. Locking o-ring keeps the barrel together and from coming loose when you're covering your lane. Straight porting to keep your marker quiet and allow consistent airflow around the ball as it leaves the bore. Unlike most barrels, Proto barrels are 3D contoured, shaving off weight where you don't need it and reinforcing it where it needs to be for those dives into the snake.
