The TRANSFORMER AUTOBOT SILICONE hop-up bucking by Maple Leaf (new version) is a newly designed upgrade component, engineered to maximize the range and accuracy of your airsoft replicas, both GBB (Gas Blowback) and standard Tokyo Marui VSR-10 spring sniper rifles (and compatible clones).
Main Features:
- Advanced Silicone Material: Made from a special silicone compound, this bucking offers superior performance, especially in cold conditions. It maintains its elasticity and ability to impart hop-up effect consistently, "warming up" faster than traditional rubber buckings and counteracting the "cold-bore shot" effect.
- AUTOBOT Design for Long Range: The internal shape of the contact patch is triangular with a "W"-shaped end. This design, combined with a large contact surface and a double triangular support, is specifically designed to optimize BB rotation for long-range shots.
- Improved Air Seal: Designed for a high-quality seal that reduces power loss and helps stabilize BB trajectory.
- Wide Compatibility: Specifically developed for:
- Gas Blowback Pistols and Rifles Tokyo Marui, WE, KJ Works, Umarex (VFC).
- Spring sniper rifles Tokyo Marui VSR-10 series and compatible clones.
- It is recommended not to install it on incompatible platforms.
