I didn't get a response the the other road so i'm reposting here.
First, I'd like to thank Mr. Kassnar for the amazing effort he has put into this thread.
Yesterday I purchased a used CD semi-auto shotgun. On the website, it looks like the VR-MC feild hunter. I really like the fit and feel on me. I took it out and shot it last night to see how it worked before the sun when down. First thing i noticed is this thing is a trick to load. I think it was mostly me, but the slide release had a very hard time releasing the cover to the magazine. It would normally open and let one or two rounds slide in, then it would click shut and i wouldn't be able to get it to move again. Pushing that button seems really unnecessary as a safety feature.
More important than me learning how to load it, it jammed on the last round. The round would not come all the way out of the magazine tube and would wedge against the plate that lifts it into position. It did this about 6 of 7 or 7 of 8 times. It also did it only on the last round, the others fed perfectly. The one time it didn't do it was when i completely loaded the gun and then fired it rapidly. Could this be a weak spring in the tube? I read some of this thread, but i don't know if this is a common/simple fix.
Also, the gun will get a thurough cleaning today and i'll do what i can to "polish" the area where the round jams to see if i can't help that out. I may get a chance to shoot it again this weekend after i have cleaned and lubed it. - edit: have shot it since and it still wouldn't feed the last round out of the tube, so i just kept it loaded so i never got to the last round and it ran fine.
I honestly can't say I'm disapointed in the gun yet. It did shoot very accurately. I busted some mini-clays with it. Then my buddy knocked the center out of a mini-clay and threw just the center(little smaller than a quarter) and i hit that. Also did the trick where you set the clay on the forearm and flick it up and shoot it. Very fun. And of course we did this is the safest way possible. Oh, in the mean time i give this new purchase a
