I'm a complete numpty and can still keep my mag going. I had it sitting in it's case in the back of my garage for about 5 years, screwed in a co2 bottle and it cocked and fired without a problem, it was still shooting about 270fps over the chrony as wellShocker_666 said:"Mags are great if you have someone who knows them well enough"
Thats the great thing about mags, they dont need spares or someone to fix them, they just keep going and going and going and going and going and going and going and going (you get the idea)
