Fits absolutely perfectly
This outer barrel makes a world of difference and I am so happy I decided to buy it. EASILY the best barrel i have seen or felt. Look at the images and see how fricken awesome they look and how CRAZY light they are compared to stock aeg outers. Will be installing these bad boys into all of my m4's here on out!!!
very sturdy and nice finish
Love it a lot! I use it in my CYMA platinum from Umbrella Armory and the included shim kit lets it fit perfect.
Lightens my gun significantly too which helps me keep up in Milsims.
The barrel is great but I got it for my Wolverine MTW and come to find out it does not fit but luckily I was able to put it on my SSR4
