Maple Leaf - 2021 MR Hop Silicone 60° Hop-Up Bucking - GBB / VSR (Yellow)

Maple Leaf 2021 MR Hop silicone hop-up bucking for GBB and VSR platforms, in 60° hardness (yellow).

The "Maximum Range" MR Hop profile uses a wider contact area and a shield-shaped groove, so the tensioner presses over more of the BB. It is intended for heavy BBs.

The degree figure is the hardness of the rubber, not the strength of the hop. Maple Leaf recommend 60° for 295-390 FPS; too soft for your power level and the hop wanders, too hard and it will not lift a light BB.

• Wider contact patch for a stronger hop on heavy BBs
• Shield-shaped groove for better response to the tensioner
• Steel C-ring retained for air seal
• No inner-barrel modification needed

Fitment: Tokyo Marui, WE and KJ Works gas blowback pistols and rifles, and VSR-10 pattern air-cocking rifles.
