"Best rail EVER! Absolutely my favorite rail by far.
by Joseph J. on 06/15/2019
"I got this rail because I wanted to make a we mk18 so I got the rail and a 9.5 in barrel and they mesh perfect together and absolutely no wobble in the rail or no shifting and it looks great and the finish is durable.

"Love it, love it, love it. There is no better way to upgrade your RIS system than this. Super simple install, instructions included and plenty of source material online. Trade marks look sick, will be buying another once the Dark Earth becomes available again. (8/1/18)

-All parts included
-Easy install
-Nothing tedious

-Hard to keep women away from

"I wanted to switch my WE M4 to a mk18 mode 1. Firstly the design is great and light weight which is great.
The unit comes with everything you want to install. But the 2 bottom barrel nut screws dont screw all the way in, so there is no threads all the way through the hole. Whats holding the the rail is the other 4 screws that are on top and sides.
Also when you install the rail if you have the stock outer barrel there will be a massive wobble. The only way to stop this is the find a screw to screw the barrel to the gas block. Thats if you have one extra (gas block) and apparently the only kit that sells it is the angrygun outer barrel kit. There was word by using O ring to stop the wobble but that does not do it.
Just thought I mention it..
Overall I am happy!

"Got it for my Krytac Alpha casue I've always loved the look of the MK18, and Krytac internals are just bar none. Comes with everything you need to mount and the instructions are good and clear. It's heavy tho, like it adds a few good pounds to the gun, I like it that way, however it may be a draw back for some.

"I really enjoy this MK18 rail. Very well made and sturdy. I have little to no rail wobble. I can confirm that this DOES FIT on a WE GBB M4 as I currently have the rail mounted onto it. The only issue that should be address is to get a decently sized oring for the outer barrel to prevent it from wobbling. After that, the rail and the outer barrel remain solid.


Good rail.
Can fit on WE GBB M4


Solid Rail
Fits on most M4 platforms (GBB/AEG)
Good quality


Takes long to disassemble because of the amount of screws you have to remove.

"Great rail to start off with. Incredibly light compared to other ris rails that I've acquired in the past. The installation is very easy and you can probably get it up and running on your reciever in less than 10 minutes. The only problem i had was that the threading on the barrel nut did not match up to that of the G&P reciever. This isn't really a problem with the rail, but for g&p users be warned that you need a different barrel nut to put this on or a reciever with the same threading as the rail.

"No doubt this is a top notch quality RIS; for me there's a satisfying weight to rail itself and when you install it onto your M4/M16 platform.

I installed this onto my KWA SR7 and I have no regrets, the new look is modern and there's not shortage on rail space either.

Decent Weight (MO)
Easy to install (Make sure you have a AR15 Wrench, which you can get on Evike too.)
Overall Amazing quality build well worth the price.

Some might not like the weight. IF you're going to a light weapon I advice getting a different rail.

Other then weight issue for some, I have no other cons.

"AMAZING RAILS. bought for my custom G&P mk18 build and wow these are the most solid rails i've ever had. holds all accessories perfectly. holds an m203 launcher and doesn't wobble at all. cant say enough about these rails, theyre lightweight and solid.

"I purchased this for my G&G M4 Blowback that had the stock polymer handguards.

I also purchased a Matrix 10" outer barrel to go with this RIS. The outer barrel sticks out about less than a 1/2 an inch. Solid construction with no wobbles. Love this rail system. Easy to follow instructions.

"Very nice rail system. this is most commonly used for the mk18 mod 1, and this rail system makes for a sexy looking gun.
Very light weight, these are by far the lightest rails that ive ever owned, you will be surprised by how light weight this is.
And for those of you who have a fetish for trademarks, this has trades up the wazoo.

Overall very nice rail system, easy to install, extremely light. 10/10
