Obviously forensic labs won't know the rifles blow off after x amount of pumps. Fwiw, I think mattys post suggests that he pumps them 15 times when checking power output, not to gain extra fpe. Not only would it be silly, but fairly tiring!

Anyway, I'd rather spend an extra £50 and get a genuine innova, instead of some clone that needs umpteen mods to get it performing anywhere like an innova.
