Silicone MR. Hop Up 70º 2023 for VSR/GBB (Blue) [Maple Leaf]

The Silicone MR. Hop Up 70º (2023 version) from Maple Leaf is designed for VSR-10 style sniper rifles and gas blowback platforms. Manufactured from high-quality silicone, this bucking offers strong BB grip and stable hop-up contact, helping improve shot consistency and overall accuracy.

The MR design features a larger contact surface that stabilizes the BB during hop application. Combined with the double air-seal construction, it helps maintain consistent air compression inside the hop-up chamber for more stable performance.

This 2023 version includes improvements such as an updated air-seal ring and a shield-shaped groove that enhances the hop effect when pressure is applied by the hop arm or tensioner.

With a 70º hardness rating, this bucking uses a medium-hard compound typically suited for setups around 360–460 FPS, especially when using heavier BB weights.
