There has always been ways of tweaking the power- changing springs, or adjusting the valve somehow to get an extra 10% but i was always told that there was no point adding a little bit of power- the difference in trajectory comes at about 20+ ftlb (and the appropriate certification to wn it). All gas guns now have anti tamper seals, and probably security fixings.
It remains the responsibility of the user to ensure that the gun is within the legal limit etc.
Yes, I'd found most of that out by digging around. My Ratty is about 7ft lbs. So you don't think it's worth getting it tweaked up to 12?
i doubt that you can. If you could, it probably wouldn't be worthwhile doing so. I think that co2 guns that run on the cartridges are usually relatively low powered. The charging equipment for the buddy bottles may be quite expensive, but my reasonably local gun shop only charges a pound to fill my bottle, so it isn't worth getting my own gear. Dont be put off by that expense if you are looking at alternatives.
