Designed for Tokyo Marui–spec GBB pistols, gas blowback rifles, and VSR-10 platform sniper rifles, the Maple Leaf MR. HOP ("Maximum Range") bucking delivers R-hop-like consistency in a simple drop-in format. It features a large, flat internal contact surface that maximizes backspin applied to the BB for enhanced long-range stability and tighter groupings. Equipped with dual outer air-seal rings to prevent compression loss inside the hop chamber and an included metal C-ring to lock down air sealing around the inner barrel.

Note: Requires an open-bridged inner barrel for proper installation.
