[Miyakawa Rubber] [Made in Japan] MIYA-Long Double Hold/Middle Chamber Gasket (2 pieces) + Dedicated Push Rubber

Similar to the standard surface hop-up system used in flow rate tuning, this system increases the contact distance with the BB bullet, allowing for a stronger hop rotation. At the same time, by using two upper points to hold the BB, it reduces lateral movement and dramatically improves accuracy.

In terms of durability, the use of a semicircular projection system for long-hanging has resulted in a significant improvement in durability compared to a surface hob packing system in which protrusions are created only through the thickness of the packing body.

This Slim Long Kake has thinner protrusions, which give the protrusions more freedom of movement and improve adhesion to the BB bullets, resulting in stable hop rotation.

・We recommend using 0.2g to 0.25g BB bullets.
・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.
