Maple Leaf AR Bolt Action Upper Receiver Conversion Kit for GHK M4 V2/ V3 GBB Series

The Maple Leaf AR Bolt Action kit is a drop-in upper receiver conversion kit designed for version 2 and 3 GHK AR15 / M4s. Compatible with the lower group of GHK M4 v2 and v3 GBB lowers, the kit converts your AR into a bolt action rifle, an effortless and easy-to-operate bolt action system, featuring a 45-degree dual lug bolt with an adjustable NPAS nozzle, the system retains most of fire selection and AR style mag swapping, retaining familiar fire controls when switching to this system.

The AR bolt action requires the use of a GHK AR15 / M4 V2 or V3 lower in order to use the system, while still compatible with the hop up set, outer barrel and handguard for the GHK AR / M4 GBBs. As a bolt action, the rifle would require the buffer and recoil spring to be removed, however, you can still retain the buffer tube or switch it to the rail stock adapter. You may need some technical knowledge to install the kit onto your GHK.
