Shroud means few barrel choices
Fast gun=more $ on paint
I love this gun. I have had nothing but good times with it. When I first got it, I had an old Revy. I was afraid I was going to chop a lot based on some reviews and the forums. However, the ACS bolt worked great. I did have to re-cock the gun often when I would out-shoot the hopper, but I would rather do that than have to clean out the inside of the gun. Now that I have an Eggy, it fires faster than I could ever want (cost me a lot more in paint these days).
This gun is perfect for woodsball/scenario. Has a great military look. It has also been durable. I have been diving around with it and no problems. Some people complain about the weight of the gun, but I actually like to feel like I am holding a weapon (I do have to admit though after a 7 hour scenario, my arms were pretty spent).
My main complaint is that you are limited on the barrels that can be used with the MR2 because of the shroud. I would think they could make the shroud opening a little larger to accomidate more barrel choices without giving up too much of the look.
I love this gun and recommend it to people who play woodsball or scenarios. Even though it fires incredibly fast, I think the weight would keep it from being a good speedball gun.
Giving it a 9 because of the barrel restrictions.
