I love CCM guns and pump kits, thats what some of my teammates shoot, they are smooth and consistent. I have shot plenty, from cockers with CCM kits, to s6's, t2's, 6.5's... but i must say, i like my MVP more then any of them with ONE exception, the bolt. The MVP is very light, extremely easy to pump, machined better then any gun i have ever picked up, very consistent and easy to breakdown. In my experience this is also the most accurate gun iv ever shot. the only issue i have had is every once in a while ill have a ball get stuck between the breech and feedneck when i go to cock the gun forward again, this can break balls or jam your gun, but can be easily fixed with a force feed, and it doesnt happen that often.
The only urine sample your getting from me is a taste test.
