"Didnt work with my G&G combat machine. I think its worth noting that this rail has two small clamps that grab your delta ring and your front site ring. This means it will adapt to most M4s unless (like mine) your spacing is a little too far. 5 out of 5 tho it is a good product just wish it fit my GnG still fits my ICS tho.

Looks great
feels great
easy to install (slip back delta ring and slap it on and bolt it to the top)
very high quality metal
feels sturdy
so much more room for "activities" (attachments)

Expensive but well worth it
small space to fit batteries in it (i was able to fit a tenergy 9.6 1200Mah in it)
people keep asking if u got a new gun because it looks awesome

"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.
