This is a flat type that does not have any protrusions inside the packing like the Marui genuine type or the V-packing.
The flat shape allows the BB bullets to be wrapped around the surface, resulting in little resistance and a small decrease in initial velocity .
・All products are made in Japan. Consistently high quality.
※please note※
If you have customized your airsoft gun or replaced parts, be sure to measure the bullet speed using a bullet speed meter to ensure it is within the legal limit (possession of bullets over 0.98 J is prohibited). Also, be careful not to exceed the legal limit during the work.
