Ryohin Buhin 5KU Lancer Type Adaptive Magwell for GBB M4 Series, 2-Piece, CNC Machined Aluminum with Anodized Finish, Black

Compatible Airsoft Guns: ■ GBB M4 Series (Tokyo Marui, GHK, VFC) Installation Difficulty: ★☆☆☆☆ - ★★☆☆☆ *Depending on the manufacturer, the original trigger guard pin may be too short, preventing the trigger guard from securing in place. A separate pin extension or trigger guard replacement may be required. This is a replica magwell in the style of the American LANCER "Adaptive Magwell." By physically widening the magazine loading opening, it facilitates magazine loading and ensures smoother, more reliable reloads. [Magazine Loading Aperture Extension] The opening is wider than a non-custom magwell, making magazine loading easier. This supports quick and reliable reloads, even during stressful situations like airsoft or speed shooting! [Two-Piece Construction] The magwell is clamped from the front and back and secured in place with set screws to apply tension. This design is less likely to wobble than a snap-in magwell, ensuring a firmer fit to the airsoft gun.
