Samm Posted July 25, 2005 Report Share Posted July 25, 2005 As most of you that played with me at AG will have noticed, my M11A1 ejects about half of the BBs in the magazine out of the ejection port. I got it a few months ago, bought the metal bolt with it and upgraded it pretty much straight away, so I can't really remember what it fired like with the plastic bolt. It also jams, but that's not really a problem on it's own, it's just caused by the BBs bouncing around the bolt and getting caught in the ejection port and stopping the gun from cycling. I've talked to John from Fire Support in whom I would trust my life to because he is very reliable, but he said he had no idea. I also phoned Zero One where I got it from but they said they can't really explain it over the phone ()and I'd have to send it out to them, but they said it's fixable as they've encountered the problem before. They said it would be covered by the warranty if the problem isn't linked to my fitting of the bolt, so to avoid the possibility of Z1 giving me a run for my money... Anyone got any ideas?

Prometheus Posted July 25, 2005 Report Share Posted July 25, 2005 Good luck Samm. I've been having this problem with my HFC M11 too. I had one suggestion that the feed lips are bent.....but I don't know... If you get an answer....let me know straight away. Mine isn't upgraded. ~P Link to post Share on other sites

Samm Posted July 25, 2005 Author Report Share Posted July 25, 2005 Well I should mention that it's a KSC, not sure if that makes any difference. The guns been like this pretty much from the box, and I'd bought a new mag with it aswell, they're not bent. Link to post Share on other sites
Prometheus Posted July 25, 2005 Report Share Posted July 25, 2005 Its probably the design of the gun thats doing it. I've heard the HFC is a very good copy of the KSC...although not as durable.....wonder huh? ~P Link to post Share on other sites
Samm Posted July 25, 2005 Author Report Share Posted July 25, 2005 The magazine lip doesn't seem to hold the BBs in very well, giving me the impression that bending them might actually help But seriously, the spring does seem rather strong, because when the magazines are in my pouches, or if they get knocked in anyway as to knock a BB out or disturb them, it can fire off a few just by itself. So it seems to me that the gas nozzle in the gun is doing the same thing, and the BBs are bouncing off the inner walls of the bolt Link to post Share on other sites
Gir Posted July 25, 2005 Report Share Posted July 25, 2005 What temperature did you use it in? Room temp? Cold? Warm? Its gonna depend on the small things. Had this problem going in full auto on my M93R, but it was cold, so the bbs would'nt even load, the gun would look like its working perfect, but ALL the BBS came out the side.

Trust Company Posted July 25, 2005 Report Share Posted July 25, 2005 My ex-friend and i had a similar problem. All we did was completely dissasemble the whole thing, i mean everything, put lots of lube on moving parts, and stuck it back together. worked flawlessly ever since. Hope that helps.

Samm Posted July 25, 2005 Author Report Share Posted July 25, 2005 In most conditions; in my house, outside when it was cold, at ArnieGeddon which seemed to be the height of British summer at about 30-35C... Link to post Share on other sites
Prometheus Posted July 25, 2005 Report Share Posted July 25, 2005 When I did mine.....it was at room temperature and up to like 80* Farenheight (sp?)....... ~P Link to post Share on other sites
shootist Posted July 25, 2005 Report Share Posted July 25, 2005 Well, when faced with an opponent, you could take out your mag, aim it in the general direction of your attacker, and shake it to deliver a stream of BB`s in his direction, :^) No, not good? drats! Two things come to mind. Keerap BB`s. I`ve found out that poor quality BB`s can vary in size a great deal, and the smaller they are off of the norm, the harder it is for them to stay in your mag. I`ve got some coming that are supposed to be +/- .01 off of 5.96. I`ve had keerap BB`s, and they came flucuate about .05 by my micrometer. Makes a big difference I think in a autoloader, the BB`s size is critical. Don't spend hundreds on a gas autoloader and feed it garbage BB`s. If in doubt, find a micrometer and measure them. Second, are you lubing your mag follower or the BB`s? I`ve found that lubbed BB`s will fly out of the mag at a moments notice, and stopped doing that (lubing them) as soon as I started. I`ve concluded that BB`s in a gas autoloader should be DRY. May be different in a AEG, where the cycling is so different, but in a gas gun, IMNSHO, they should be DRY. Hope this helps, Cheers, Randall Link to post Share on other sites
Prometheus Posted July 25, 2005 Report Share Posted July 25, 2005 I'll try the better BBs......but this doesn't seem to be themag. I'm looking at it now and it seems to be that one BB will stop in the barrel and then the other BBs can't get out so they bounch back into the chamber and bolt....thus jamming it. Sorry to hijack the thread Samm. That is just mine though. Samm, whats yours doing in respect to my problem...? ~P Link to post Share on other sites
Lance Jackass Posted July 25, 2005 Report Share Posted July 25, 2005 I know this doesnt help but ithink its just its insane rate of fire that does it. Are you feeding this baby green Does it do this in single shot? Link to post Share on other sites
doc_newstead Posted July 25, 2005 Report Share Posted July 25, 2005 Well not really Lance, because all M11's have a mad ROF, even on 134a. Link to post Share on other sites
Lance Jackass Posted July 25, 2005 Report Share Posted July 25, 2005 hmm. Okay my bad. Maybe (another random stab in the dark) the spring needs wearing in/weakening? I give up. "taxi?" Link to post Share on other sites
Marlowe Posted July 26, 2005 Report Share Posted July 26, 2005 Oddly this occurred with my first mac11 (as any who saw me at AG may / may not have noticed, I'm stupid enough to own two, complete with those naff laser sights), and the solution, as idiotic as it is, came about simply enough for me by simply oiling my mac well (but not excessively, as Gretik managed - the thing shouldn't ooze oil, but merely be lubricated). As stupid as it sounds, lubricating the bolt a little more seemed to cause the problem to simply vanish for me, so perhaps in my case it was related to the manner in which the bolt was cycling rather than a feed lip issue. Both of my M11s seem to love a regular lubing, and appear to cycle much smoother. I can only assume the open bolt nature means the lubricative properties of the silicone oil dissipates faster. However, I appreciate that may achieve nothing in your case - and I think I possibly had this discussion with you at AG05. If I already have then my apologies. Link to post Share on other sites
doc_newstead Posted July 26, 2005 Report Share Posted July 26, 2005 My M11 was a slippery as fish when I was done with it. It worked fine and cycled smooth, but unless you strapped it to your hand with ratchet clamps, it would slip from your palm at will. I recommend a fish-tank full of silicone oil and a pair of marigolds (No sniggering at the back...) Link to post Share on other sites

doc_newstead Posted July 26, 2005 Report Share Posted July 26, 2005 Arf! I have the feeling Samm will be patronised to death with our lube advice, but worth a shot eh? And whilst I'm here... If anyone can get me a KWA/KSC M11 HOP rubber and mag seal, I will do your washing up for a month. Seriously, PM me if you can at all help. Even if you order the parts yourself from a shop and then sell them on to me at a mark-up, I will consider it. /off-topic Link to post Share on other sites
Marlowe Posted July 26, 2005 Report Share Posted July 26, 2005 I've got a spare mag seal. Not sure if I want to part with it yet though, as I'm sure one of mine will leak as soon I get rid of it... Link to post Share on other sites
doc_newstead Posted July 26, 2005 Report Share Posted July 26, 2005 My M11 has remained inactive since October 2004. You owe it to airsoft to do my dirty work for me 01 quoted me £10 for the parts, and yet still I put it off like so much Maths coursework... Link to post Share on other sites
Samm Posted July 26, 2005 Author Report Share Posted July 26, 2005 Ahh yes, the lubricating story I think it's properly lubricated, but the problem that seems to come to mind is that I'm not lubing a specific part properly? More worry in that you don't have the metal bolt do you Marlowe? What about you Doc? I think that also may be where the problem lies Link to post Share on other sites
Marlowe Posted July 26, 2005 Report Share Posted July 26, 2005 Um...Yes, I do. First thing I did to the mac I bought off havoc. The new one doesn't have one, but that's because I bought it boxed with a mag for just £30 and have so far simply just thrown a plastic mag in that one. I had the issue upon initially firing the mag bolt m11, but as I said, the lube down the top and side of the bolt fixed it. It was nothing to do with the feed lip of the magazine in my case, but Plasticmag's suggestion does appear to be a logical one. Sorry I can't help more. Link to post Share on other sites
