While teching a teammates Extcy this weekend, we noticed that the backcaps were very difficult to remove and took alot of force to turn. When we finally removed the backcap, the threads were slightly flat on the cap. We thought maybe this was due to it being a new marker and possibly just a tight fit. It wasnt...it turned out to be the back body screw under the backcap was possibly screwed in too far and was protruding slightly into the backcap. So if you run across this issue, DO NOT FORCE the backcap off.......try loosening the underbody screw first and see if that helps. I will call Dave at Gog and bring this up to him as well.
There should be a washer on the rear grip frame screw that goes between the screw head and the frame. The washer is there incase there is a slight variance in screw length from screw to screw, when there assembled. Give me a ring when you get time Prettyboylou.
I've never had that problem for all the rental vibes and sp-1's I've tech at my work... Same for the handful of Envy's and G-1's we have now. I'll keep eye out for that problem though... thanks for the heads up.
I also have this issue. I bought a new extcy around 3 weeks ago. When I went to back out the bolt sleeve (back cap) it was very difficult and binding. When I got it out the threads were flattened and small pieces of aluminum were in the hole from the bolt holding the frame to the breech. The frame bolt appears to be slightly too long. There are no washers on mine and both the front and rear bolts are the same length. I have been getting the run around from GOG for the last week and half. They said they would send me a new part, but needed to talk about it first on the phone. I have tried calling numerous times, but noone answers. I have left my number, but never get a call back. After saying they were going to send replacement parts, they decided they wanted me to send it in to be worked on. It is obvious what the problem is and that I need a new back cap and shorter frame bolt. I don't know how safe it is now and I am concerned that the messed up threads will cause a problem in the future. I am seriously considering getting a different gun at this point.
Could be a machining problem or its sitting in the paint process too long leaving too much flash on the threads. Could always try some triflow on those threads, triflow is great for those tight situations.
The issue was variances in screw lengths being used. It could be off by just a a thread or two which would bind up against the bolt sleeve. Gog picked up on this and added a washer to the screws. Simple solution. Unless your threads are totally gone on the bolt sleeve, you should be ok. They might want to just look over your marker to make sure they dont have any other issues they should look at. I know the boys over at Gog have been a bit busy with preparing to attend the Living Legends event as well but I will make sure a rep pops to try to help you out tbcostomz
The threads seem to hold, but I am concerned that they will strip out or cross thread in the future. I understand issues like this happen from the factory. All I want from them is to send me a new bolt sleeve and shorter bolt or washer. The threads on the breech are fine. It is pretty obvious what the issue is. Keith Short has responded to some of my emails and said he would send the parts, but I can't get him on the phone after he said he wanted to talk to me. I have sent numerous emails, called 6 times, and left 2 voice mails. If you have someone elses contact info please pass it on. Thanks
