CQB Master CNC Selective Rails System for M4 series Airsoft Rifles - Dark Earth
$99.99 $65.00

This rail system is great! It's solid and definitely adds a mean look to your gun. Ease of installation depends on what brand of gun you have. So far I've tried it on my KWA M4A1 and fits perfectly, but for my WE Tech M4, I had to modify the rails on my upper receiver to allow this to fit. There is also no wobble with this system at all, which is a huge plus if you're using a vertical grip or any other attachments.

Although it's designed to store batteries, it will also depend on the diameter of your outer barrel. My WE Tech M4 outer barrel has a small diameter which allows me to fit a small or nun-chuck type battery inside with little problem. But with the KWA M4A1, having a larger outer barrel diameter, these types of batteries wont properly fit at all. Li-Po batteries should be able to fit, but I haven't tried yet.

The paint for this dark earth version is pretty well coated, but the paint chips off around the inner hinges (I've also bought this system in black and it does the same thing). This isn't so much a problem since it's within the rail system and can't be seen externally.

Pros: Looks great. Solid and no wobble. Can store batteries (Depending on your outer barrel).

Cons: Paint scratches within the hinges. It's a bit pricey, but hey, if you've got the money go for it. Installation might need modification.
