Looking for a life changing experience? KJW has done it again. The classic KJW M4 CQB GBB-R is now available with a full metal receiver set. If you thought the original was grin-inducing, the full metal version is a jaw-dropper.

The 3rd generation of KJW M4 CQB has seen some great improvements over the last 2 versions. Most importantly, the buffer tube assembly has been modified to allow for more customization with aftermarket stocks. The lower receiver and valve knockers have also seen some minor tweaks. With these internal modifcations, the most obvious chane is external. The new Gen 3 KJW M4s feature a flat, almost textured dark grey finish. Gone are the days of the semi-gloss black finish.

Introducing the premier of the M4 CQB gas blowback full metal rifle, this KJW M4 is truly one of a kind. Being one of nicest and highest quality full metal M4 GBB-R in the world, this is a must-add to your airsoft collection.

We recommend this gun for all players entry through competitive levels.
