Madbull Spike's Tactical Licensed Spike Bar Rail for M4 / M16 Airsoft AEG Rifles (Model: 12" / Black)

"Bought this to make a Spikes Tactical Compressor inspired M4. Solid rail system, looks fantastic, and mounting is pretty straight forward. Might need some barrel shims to get the holes to line up, but that's expected when installing rails.

Inner diameter of the rail is about 45mm. So you will be able to use up to a 44mm OD muzzle/suppressor inside the rail. The length from the front of the receiver is actually just under 9 1/4 for my application. I've had no problems putting any attachments on mine aside from my AFG1. The raised sides make it not fit, AFG2 on the other hand fits fine.

"VERY nice rail system by Madbull. Very solid.
Lightweight, but rigid. Nice CNC cuts and craftsmanship.
The mounting design is intelligent, with two anti-rotation edges that fit against the receiver on both sides.

I have to say - this rail is FAT. Quite girthy. It takes your whole hand to wrap around it with room to spare. Kind of funny looking when it's on your rifle. Makes it look like it has a sausage for a hand guard LOL.

I own virtually every rail Madbull makes and I like this one a lot. A nice strong, lightweight choice for those who want an alternative to the ubiquitous MK18.

"This product is high quality. I got this rail because how aggressive it looks, it does meet that constraint. The Install was easy on a G&P m4 body. The design of the rail system is good, there is a notch where the rail system lines up with the upper receiver so it will not become loose. It gives a clean look to your gun with the monolithic rail. Also this system is very light for how long the rail is. This rail can take the abuse of being in a desert and since it is aluminum it will not oxidize as easy. One thing to watch for is that the rails have an edge so it can cut if you are not careful.

Pro
Light weight
Will not come loose (once barrel nut is secured)
Easy install

Cons
That this is a map item
Rail edges

"its simple the best rail system in the world

"One of the coolest rail ever, but it does has a con, 50% of my accessories did not fit on the rail, I have to sand my accessories to make them fit. You need buy an O ring in the hardware store for the barrel nut.

Pros:
Cool looking
Nice finish

Cons:
Can't mount accessories(need modification)
Pricy

Don't get this rail if you don't want to do modifications to your accessories. But this is a really cool rail.

"I think I bought this and it was the only one because now it shows "out of stock"

Anyway, here's my review:

THIS RAIL IS BEAUTIFUL AND AMAZING! My aeg looks so aggressive and awesome now. The build is extremely solid. When it was installed on my aeg we needed to put a couple of washers so that the barrel nut lined up just right, and some very slight work with a dremel had to be done so that the top rail lined up with the top rail of the gun. I'm not sure if this small amount of work would have to be done for every aeg. The only real complaint I have on this rail system is the paint. The feel of the texture is rough in a way, like it was spray painted and not really "finished." Anything sharp and metal will scratch this really easily, but I haven't got to take it to a real skirmish yet and I do play rough. As far as a battery goes (if your aeg is front-wired), you will need a PEQ box.

Final word? I'm Commander Sheperd, and this is my favorite rail system on the Citadel

Pro's:
Aggressive
Unique
Plenty of rail space
Amazing construction and quality

Con's:
Scratches easy if you're not careful
May need a little modification to fit securely
