EDIT: I can't figure out how to imbed images on this forum so here's a link to an album containing the pictures: (http://imgur.com/a/Nqn1h) So I recently bought a used WE Hi Capa on my local airsoft forums and the day I went to pick it up the seller had left the gun in is car during a warm day, and it was having some cycling issues. We figured the silicon just evaporated off the nozzle so I sprayed it and figured it'd be good. I finally got a chance to shoot it today and it's still having the issue. It shoots of the round but then the slide gets caught back in this position: Same deal, back by the hammer so you can see a bit better: It also seems like the nozzle is poking further out farther than it should as shown in these two pictures: I added more silicon to the nozzle but it was still having the same issue. I have to push the back forward in order to shoot another shot. I figured no big deal, the gun came with an extra slide so I'll put that on and it should be fine. Well unfortunately I had the same results with a completely different slide. I did some research and some people said lubing the mag at the gas release and feeding spot fixes this problem, still no dice. So I'm kind of at a loss for how to fix this, if anyone could help that would be great. Here's some of the data concerning the gun and the issue: Using propane adapter with silicon to power gun. The slide doesn't catch when I manually cock the gun. I've tried two different slides and get the same results, is this a magazine problem? If anyone could help me out that'd be awesome!
