LogieBear Posted February 24, 2015 Posted February 24, 2015 I only very recently went and got myself the M15, I was well impressed. The only problem was when I got home, the gun wasn't feeding right. I fully stripped the gun and lubed and cleaned it, and it worked like a charm. But last weekend I brought it to the first game I had used the gun, and it wasn't feeding correctly. Semi-Auto only worked for short amounts of time, maybe 4-5 shots, where then I would go onto between 10 and 15 shots where nothing came out. Full auto had the same results. This is with a full magazine (which I did get separately), and a mid cap, so no winding or rattling . After taking it home and completely stripping it, checking for dirt and debris (where there was none) down the barrel, in the feeding tube and in the hop up, the gun was still not feeding right. I lubed it up with plastic lubricant and a bit of silking (from WE gun cleaning kit), which after reading a few problems online, seemed to work for others. However, I got the same results. If anyone knows how to fix this problem, please let me know as this is my first gun (after using friends and rentals) and it'd be a bit pants to see it break down so early N.B. this was a pre-owned gun which I bought from one of the local sites for £80. The guys that run the site are trusted throughout the airsofting community of Antrim. I had asked them were they selling them off because they were broken, and they said no, that it was to deal with the extra rentals that would come up and play during the summer
Supporters Samurai Posted February 24, 2015 Supporters Posted February 24, 2015 One of the M4's most problematic points is the magazine. Try with different ones. Also try yours pushing it back or front or up while firing. Airsoft_Mr B 1
RR01 Posted February 24, 2015 Posted February 24, 2015 Feed problem like that can sometimes be caused if the hop unit isn't pushing back tight against the gearbox. Well used guns will sometimes lose the small spring that sits on the top of the hop unit to push it back against the gearbox when the receiver is fitted and can mean that the hop isn't sitting quite right in the mag to allow clean feeding of the BBs. The other possibility is that the hop has been changed and might not be lined up correctly. I had that problem with my custom built M4. My preferred hop unit just would not sit right and was about 1.5mm out of line. A different make hop was fitted and worked fine, even though it wasn't as good a unit as the other. The other possibility is that you have the hop turned too far on, which jambs a BB in the barrel.
LogieBear Posted February 25, 2015 Author Posted February 25, 2015 I pushed the magazine up, and it seemed to sort the problem. But how do I make it stay permanently in that position?
Supporters Samurai Posted February 25, 2015 Supporters Posted February 25, 2015 Stick a thin piece of plastic or a few layers of duct tape in the back of the magwell. Something like this: http://imagizer.imageshack.us/scaled/medium/853/43sb.jpg It's not an M4 but you get the picture. This pushes the mag forward, so the feeding part moves up. LogieBear 1
