Wobbly, plastic, and changes the way you shoot your marker.
Review:
I wanted one because I'm a dedicated woodsball/scenaio player. I wanted the military look, plus wanted to run my 98C on a remote and like to shoulder and sight down my Tippmann like a rifle.
When I first installed the product I loved it, then I put on my mask! Once the mask is on you have to look down the side of your barrel rather than the top. I was very dissapointed.
The construction is poor; the thing is made from plastic and is slightly wobbly.
Conclusion:
In summation, save your cash unless you don't mind the modified sighting. Mines going into the tried but failed pile of stuff that I'll take with me to trade or sell at the next scenaio game.
