the clears are quite soft and taht is part of the benefit and allows them to work better, i get taht they could rip easier bcuz of the softer material, but why would taht jam or what kind of problems would this cause other than not getting the proper backspin on the bb?? unless maybe if the rubber rips and then is dangling in the barrel, would taht cause the jam?

i dont plan on havin my gun go anything above 400 fps once i do upgrade it, so i figured the clear would still be good, as i have read ppl using them in guns that shoot just under 400, am i misinformed and should be looking into a different hop up rubber???
no. the use of the clears with a madbull tight bore barrel will cause jams from an eventual tear. the mb tbb outer diameter is smaller which allows the clear to move too much causing it to pull away and tear eventually. they work fine and seal great but will tear. had it happen in two different guns that had the mb tbb installed. both were shooting sub 350fps
