Well, I am thoroughly disappointed.
Yesterday, my maximum range was 200 feet with a .43g bb, shooting in the vicinity of 450 FPS. Not sure why 200 feet was as far as it was going, but I continued to shoot.
Those shots would over hop, under hop, then rarely curve to the left.
Near the end of the day bbs stopped going 200 feet. That became a pipe dream, because now the gun was shooting a mere 10 feet. Yes, 10 feet.
I hand tested the barrel seal and found that the barrel could freely move within the bucking because the chamber only holds it in via friction, what fun. I pushed the barrel closer to the chamber, it became all sealed up.
Shot it again, first shot flies…11 feet! QUE BUENO! The next few shots, well, some didn't even come out the barrel. It became obvious that I was losing massive amounts of my CO2 somewhere between the barrel, patch, bucking, chamber, nozzle, bolt, and magazine.
I began my autopsy in that order, reversed. I noticed to issues with the magazine, bolt, or the nozzle when hand tested. My investigation continued onto the chamber. The first thing I notice is a small piece of rubber sticking up from the bottom, the first sign of a ruptured bucking. I decide to bypass the surgical removal of the chamber and went straight to the bucking and barrel. My diagnosis concludes as so: The barrel shows that the ER-patch had torn in half and the bucking was torn near the nozzle end.
Not only was the patch torn in half, but it looked like a dog ate it, crapped it out in the mud and let it sit while getting run over by ATVs. The patch, needless to say, was in very bad condition. What happened? I have no clue.
Tony Zito and I exchanged several emails prior to the findings, starting with very easy suggestions, like barrel spacers. Yeah, those will increase the range by 190 feet. Easily. He eventually told me just to check the bucking and stuff and report back, I had already done that when I received the email, I'm anyone looking to fix a rifle would have done that anyway.
All in all, I am VERY DISAPPOINTED with everything. Lets begin with this: I spent more than $200 on the project. Thats $50 in parts and $160 in services from Tony Zito. On the second day of shooting, everything explodes. I'm telling you, if a KJW M700 had an appendix, it clearly ruptured. What does the surgeon do when the appendix has already ruptured? They clean it up and hope the patient lives. That is what I am going to do.
I'll clear this up with Tony and the mess from my gun, and hope that the gun lives.
Thanks for following this project, to whomever actually did, it's over now. I do NOT recommend this. At All.
So what am I going to do, I'm out a good amount of money and I've got a small skirmish tomorrow. I replaced the internals with everything old. Angel Custom barrel, stock rubber, stock chamber, stock nub. Performed better.
