Increasing your gun's performance has always been a must, and having an accurate barrel is number one. Our proto barrels are made to the highest quality standards and are ultra accurate.
These barrels go through a five step honing and quality control process to ensure each one is as precise as we designed them to be.
Made from lightweight 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.
Straight porting to keep your marker quiet and allow consistent airflow around the ball as it leaves the bore.
Zero step diameter bore ensures consistent level.
Proto barrels are 3D contoured, shaving off weight where you don't need it!
