Maple Leaf Outer Barrel Base for GHK M4 / AR GBB – this upgrade for your replica

This outer barrel base is a mounting component for your GHK M4 or AR15 GBBR. The part connects your outer barrel to the upper receiver and allows you to install different barrel lengths. If you want to build a shorter or longer setup, or if your current barrel base is damaged, you can replace it with this one. The airsoft outer barrel mount system from Maple Leaf gives you more flexibility in your build.

Technical specifications

The barrel base is CNC-machined from aluminium with a black anodised finish. The part features a 14mm CCW thread for muzzle devices and comes with an M3x4mm set screw for alignment. The mount is compatible with three barrel lengths: 5.1" for 180mm inner barrels, 3.9" for 150mm inner barrels, and 2" for 100mm inner barrels. The construction ensures a stable connection between barrel and receiver.

Compatibility and application

This barrel base is specifically designed for GHK M4 and AR15 GBBR replicas. It fits standard and custom builds where you want to adjust the barrel length. Installation requires basic technical knowledge – you need to be able to remove the old barrel base and align the new one correctly. The part works with standard GHK upper receivers and accepts Maple Leaf outer barrels in various lengths.
