So I received my new toy in the mail, took it out of the box, test fired it, and immediately noticed a severe lack in long range capabilities. I wrote it off as being an unadjusted hopup, so I attempted to fine tune my rifle, to no avail. No change in performance whatsoever. I cracked it open, to find no nub. Well, I wasn't about to send it back for such a minor problem, so I put in what I believe was a new systema bucking and nub. Reassembled it, nothing.
contact KWA first. They have excellent customer service. Im sure if you explain what your problem is then they will most likely send you a nub. Talk to them first, i cant stress that enough, dont take your gun into aex for a repair you can do at home. When you get a new nub, clean the bucking and the hop unit with warm and slightly soapy water. The hop unit is most likely over greased and if you place your new nub in the grease, it will suck it up like a sponge. That is what happened to mine, i contacted KWA help desk and they guided me through it via email which they were very prompt in replying.
