Unicorn Airsoft 70 Degree Competition Grade GBB Hop-Up Bucking – Silicone Rubber | Black

Fine-tune your gas blowback airsoft gun with the Unicorn Airsoft 70 Degree Competition Grade GBB Hop-Up Bucking. Made from durable silicone rubber, this replacement bucking is designed for compatible gas blowback pistols and rifles using Tokyo Marui-style hop-up systems.

With a 70-degree hardness rating, this bucking provides a slightly softer alternative to the 80-degree version, making it an option for players tuning medium- to higher-powered GBB setups. Its contact surface applies hop to the BB as it passes through the chamber, helping you adjust BB flight and shot consistency when paired with a properly matched inner barrel and hop-up assembly.

The Unicorn 70 Degree GBB Bucking is listed for use with compatible Tokyo Marui, VFC, KJW, and other TM-style GBB hop-up units. Whether you're replacing a worn factory bucking or experimenting with a different hardness during a custom build, it offers another option for dialing in your gas blowback airsoft gun.

Compatibility note: Confirm your gun's hop-up chamber and inner-barrel compatibility before purchasing. Bucking hardness alone does not guarantee better accuracy or range; results depend on your gun's power, BB weight, hop-up adjustment, and overall configuration.
