CQB Master CNC Selective Rails System for M4 series Airsoft Rifles - Black
by Tony L. Date Added: January 21, 2009
Bought this last week and it arrived 4 days later...not bad, considering it was MLK weekend.

To answer an earlier review, Yes. This system does fit a 2000mah 9.4 intellect nunchuck battery, fuse or no fuse. The rails itself are pretty light for what they are, and they feel like a comfortable enough handguard. Also, the option of picking and choosing where you want the rails to go makes life a lot easier, with no need to go out and get rail covers.

Installation is pretty quick. It fits my KWA M4 perfectly fine. took about 3 minutes for me to figure it out and get it on the gun. The bottom half is detachable, so installation and removal of forward batteries is a simple matter. While there is no sling mount on the front, I have a 1 point sling, so it's better for me anyway. For others that require one, it would be easy to mount one on the rails, or simply screw one in somewhere along the hand guard.

The rail on top of the M4 upper is used as the attachment point for this system, so anyone with a high rise scope may need to consider getting low profile scope rings, as the system does raise the top rail about a cm.

The finish scratches off a bit easily though, and the over all weight of the gun does increase, especially forward, causing a slight balance problem.


Easy to install.
Selective rail handguard allow comfortable grip.
Large, easy access handguard battery compartment.
Looks sexy....really, its a pro.


Finish scratches off way easily...nothing a bit of touch up or a paint marker won't fix.
Makes the gun front heavy, but you shoulda realized it would when you plan on adding a bunch of metal to the front of the gun, if this is a problem, consider rerouting your battery to the rear and getting a crane stock or a full stock.
