Hop-up rubber Lonex

The Lonex 50 Degree Bucking is an easy way to increase the performance of your airsoft gun. The Bucking is what the BB contacts before leaving the barrel. As the BB gets pushed inside the bucking, the air nozzle will seal against the bucking lip to ensure that the air being compressed from the cylinder travels completely through the barrel leading to maximum velocity output. A damaged bucking would lose air compression leading to a lower velocity output. Keep you airsoft gun performing like new with the Lonex Bucking. This bucking is designed for airsoft guns with a velocity output below 130 m/s.
