SixtyNiner Posted February 17, 2013 Report Share Posted February 17, 2013 Thanks to those who commented on the reliability of the PTS PMags. I shall be ordering some very soon! Quote Link to post Share on other sites
crash0744 Posted February 20, 2013 Report Share Posted February 20, 2013 That is great info! Does the window guy told you how to do the welding? I broke my lower as well and perhaps I can weld it instead of getting a new lower I've used these rods before on motorbike frames http://www.durafix.co.uk/ It's an alloy braising rod and works very very well with aluminium.

hardboiledcop Posted March 12, 2013 Report Share Posted March 12, 2013 (edited) Hi guys, tried upgrading my sopmod yesterday and after installing a set of prommy high torque gears, piston head, and tightbore, I put it all back together and everything SEEMED fine. However when it came to shooting, I found that I now need to push the magazine up in order to get the bb's to fire, since I don't fancy holding my magazine up all the time I was wondering if any of you might know the cause? -- If it helps, much like whenever I put some ikea furniture together, I wound up with a single part left behind (I think at least), It is a small silver cyclinder, about half a centimetre in size. Any help would be much appreciated! ie, HELP ME Edited March 12, 2013 by hardboiledcop Quote Link to post Share on other sites

VIPER-GR Posted March 12, 2013 Report Share Posted March 12, 2013 I had similar problem but i have a socom and it was caused by the front wiring, so in your case give us a pic of what you see , and also a pic of the silver cylinder would be helpful. Quote Link to post Share on other sites

How utterly unhelpful, my sopmod has been opened a couple of times due to failures of stock internals. -- VIPER-GR: Mine too has been front wired, could it be as simple as a part of the wire 'propping up' the barrel and therefore creating a slight gap between it and the magazine? I would have opened her up again straight away however it was such a hassle fiddling with the wiring and the delta ring that I thought I'd call it a night. About the cylinder, problem is I don't even know if it came out of the gun, does the anti-reversal latch have a 'sleeve' around it? it is about that size.. I'll try and take a picture when I can..

VIPER-GR Posted March 12, 2013 Report Share Posted March 12, 2013 dont open it just move out the wires to the side and you will be ok. i had the exact problem myself, or if you open it do a better routing to the cables.... Quote Link to post Share on other sites
hardboiledcop Posted March 12, 2013 Report Share Posted March 12, 2013 Just removed the barrel and shifted the wiring to the side (or at least they should be to the side, its a bugger to actually see where they are going) Noticed the barrel had some wobble too, now its very firmly in place, however now it won't fire bb's even with the mag pushed up. -- Really tempted to just hand it in to fire-support and have them sort it, only downside to that option is that their current turnaround on repairs is nearly a month! sigh..

Megalomaniac Posted March 12, 2013 Report Share Posted March 12, 2013 Wiring miss routed can do that, magazine catch being installed too loosely can do that, also look at your air nozzle if it isn't seated right it will sit forward just a hair and block feeding.

SixtyNiner Posted March 12, 2013 Report Share Posted March 12, 2013 Like Viper, my first guess would be fouling between the mag, hop unit and the wiring. If the gun started out as a SOCOM there are little clips for routing the wires and keeping them tucked safely to the side. I'm not sure if the SOPMOD includes these. Looking in to the mag well is usually enough to see if a wire might be causing a problem. Does the magazine lock in place as it should? Have you checked it with other magazines, or just that one? I can't think of any small silver cylinders that you might have missed, but it's a while since I looked inside my gearbox. Is it big enough for a BB to pass through?

hardboiledcop Posted March 12, 2013 Report Share Posted March 12, 2013 Nope not big enough, about 3 or 4 mil wide. Looking into the magwell it looks the same as it did prior to takedown, there are little clips keeping the wiring out of the way of the magazine, it is more difficult to tell from the hop unit onwards whether the wiring is causing an issue. The magazine catch is fitted correctly, and the mag positively snaps into place as per usual. I am using the magpul sopmod pmags, however prior to takedown these functioned flawlessly. thanks.

hardboiledcop Posted March 12, 2013 Report Share Posted March 12, 2013 incidentally, reguarding the air nozzle, can i tell if it is out of whack without stripping the gun down again? what position should it be in when i look into the magwell? Quote Link to post Share on other sites
druid799 Posted March 12, 2013 Report Share Posted March 12, 2013 On the problem of non feeding my Sopmod won't feed the last ten or less bbs out of any of my mags , feeds fine until you reach about twenty or so bbs in the mag and it starts miss feeding then when it reaches the last ten bang won't feed any of them at all . have tried three different receivers on it and it happens with all of them so looks like the problems with the lower .

VIPER-GR Posted March 12, 2013 Report Share Posted March 12, 2013 DRUID if u have the magazine adapter then you like me you will have 4-5 bb's left in your magazine. On the original mags however i always shoot to the last one, maybe you have to clean them? Quote Link to post Share on other sites
Megalomaniac Posted March 13, 2013 Report Share Posted March 13, 2013 Give your mags a deep cleaning, mine miss fed and failed to lock after being loaded up with Biovals for too long. Quote Link to post Share on other sites
SixtyNiner Posted March 13, 2013 Report Share Posted March 13, 2013 hardboiledcop: I've been giving some thought to your feeding issues. I can't recall a metal cylinder or sleeve on any part of the gearbox, but it does sound like it might be part of gear axle or something. If so, having that part missing would likely cause problems with the gearbox not cycling properly rather than just feeding issues. My hunch is that you have the tappet plate or air nozzle fitted incorrectly. When reassembling mine I did notice the air nozzle had a little 'bump' that fitted into a notch on the tappet plate. It was possible to instal the air nozzle without the bump and notch aligned, and this caused the air nozzle to be slightly out of true with the hop. Maybe enough that it won't correctly pick up the next BB without some pressure being applied to the mag. Otherwise, like other people, I'm thinking the hop unit isn't seated properly. If feed tube isn't slotting in to the magazine correctly it might not be releasing the little catch that holds the BBs in place inside the mag. When you take the magazine out of the gun do any BBs drop free? That would give a clue to that area. And when you installed the TB barrel did the hop rubber or nub get kinked or twisted out of shape? I don't think that would be it but worth checking if you have the gun apart. Finally… if you decide to send the gun to a tech for them to fix it would be worth contacting Eagle 6. They specialise in TM recoil guns and the last I heard (admittedly a few months back) they had a turn around of about a week. Quote Link to post Share on other sites
Megalomaniac Posted March 13, 2013 Report Share Posted March 13, 2013 100% it sounds like a nozzle or tappet issue issue, if the nozzle is in properly you won't be able to twist it, if it isn't it'll twist and seat back a hair. That little bit extra that it sticks out is enough to cause a constant failure to feed on semi and an intermittent failure to feed on f/a. Quote Link to post Share on other sites
druid799 Posted March 13, 2013 Report Share Posted March 13, 2013 (edited) Can't be a dirty mag issue as they all feed empty in my scar , socom and second Sopmod . Edited March 13, 2013 by druid799 Quote Link to post Share on other sites
Jas Posted March 16, 2013 Report Share Posted March 16, 2013 Just removed the barrel and shifted the wiring to the side (or at least they should be to the side, its a bugger to actually see where they are going) Noticed the barrel had some wobble too, now its very firmly in place, however now it won't fire bb's even with the mag pushed up. -- Really tempted to just hand it in to fire-support and have them sort it, only downside to that option is that their current turnaround on repairs is nearly a month! sigh.. Take a look at the feeding port on the hop up. I had a problem with my mags not feeding properly and it turned out that the lip of the hop up feed port was slightly damaged. I took a knife and cleaned the edges and its feeding perfect. Quote Link to post Share on other sites
hardboiledcop Posted March 16, 2013 Report Share Posted March 16, 2013 If you are correct about the nozzle having a little bump to align it, but still able to go fit without, then I'm certain that must be the issue, the wiring isn't in the way, and despite hating fiddly operations, the hop unit is certainly assembled corrected and in the right place. Must be the nozzle. -- I'll get onto fixing that this evening, in the mean time, one other brainstorm if you would... Is there anyway to remove the rattle/spring vibration after firing? What I mean by that is that there's a veery audible rattle, and basically the weapon does not sound as crisp when firing as it once did (this change occured after Zeroone fixed a shredded piston for me and Ground Zero. It's no bother really, and hasnt affected operation, it just doesnt sound very nice, kind of the reason I moved over to the ak as my primary gun. ta. Quote Link to post Share on other sites
Megalomaniac Posted March 16, 2013 Report Share Posted March 16, 2013 Sounds like they cocked something up when they worked on it, but without it on my bench I can't blame shoddy tech work. Quote Link to post Share on other sites
lacanuck24 Posted March 18, 2013 Report Share Posted March 18, 2013 Does anyone have any experience removing power brakes from the loading nozzle? Picked up a new CQB-R in Korea, but the government requires power brakes giving me a wonderful fps of 120fps! Woohoo!!! Anyway, my mechanic is about an hour away and I don't have anytime to get up there for a while. I know this is a rare thing but if anyone has suggestions/experience it would be greatly appreciated Quote Link to post Share on other sites
