New to airsoft? Here are some safety tips for airsoft guns that we recommend following.

The Modify Bore-Up Air Seal Nozzle is made specifically for Modify bore up cylinder heads. Bore up air seal nozzles have larger internal diameter than regular nozzles to allow more air to propel the BB. The nozzle features an internal O-ring to prevent air leaks around the cylinder head. It may fit other bore up cylinder heads, but this cannot be guaranteed by Airsoft GI.
