Teflon Tape Hopup Mod:
Some people may have already aware of this but it is still good to be publicly announced.
Wrapping telfon tape around your bucking when your bucking is already on your inner barrel. Our experience is to wrap the entire bucking. However, wrapping the front part only will do the job too. It really varies from one to another so take time and try it for several times until you find the sweet spot for consistency and smoothly(over tighten will cause jamming).
Goal is to improve hopup consistency by creating a hard stop before the nub.
It will also increase a bit FPS (just like you use Oversized O rings, it increase the friction between shaft and bucking lip).
-Wrap it evenly, if you feel your bucking is bending to one side then stop and redo the wrapping.
-Dont wrap too much tape on or it will cause serious jams> Or to say, dont go too greedy.
-Dont expect to do it perfectly at first attempt. Sit down and Try it patiently for a few time until you find the sweet spot.
