Madbull x Spike's Tactical Spike Bar Rail for M4 / M16 Airsoft AEG Rifles
(Model: 7" / 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.
