I agree with Mike! The factory comb hardware sucks bigtime. I purchased a replacement set from Joel Etchen. I have been shooting a 682 Gold E every since they came on the market. I love mine. I have had absolutely no problems. I recently added a new unsingle barrel to my combo.
Great gun. I love mine. Got the combo set and have been shooting it about 4 months and it breaks the targets hard. Patterns great and as for the stock system, not that great, but hey once you get it set no need to mess with again.
Bought mine about a year and a half ago and love it. Take their advice and change the comb hardware right away. The plastic junk it came with can cause the comb to crack. Excellent shooter and not sorry i bought it at all.--Matt
