Neilbarker Posted October 7, 2015 Posted October 7, 2015 I have a problem with my we m4 gas mag. It's a double stack mag and as I'm firing it, the top two bbs seem to jam and the gun just cycles gas. I'm just wondering if anyone knows what's causing it and how to fix it? Thank you
straffham Posted October 7, 2015 Posted October 7, 2015 Does the mag wobble in the mag well? And does the gun fire but just not pick up a BB? If the answer to both is yes it sounds like the mag is not seating correctly and may need shimming slightly so its more snug in the magwell. If the mag is firm it sounds like an issue with the air nozzle not pushing the BB into the chamber.
Neilbarker Posted October 7, 2015 Author Posted October 7, 2015 Nope it's seated properly and yeah the gun cycles just doesn't Fire bbs. The bbs are jammed under the feed lips. I can see there's two bbs jammed further down and then there's one that rattles around on top and even if I pull the follower down they still stay jammed in there but the bbs below it come down with the follower
Root Admin proffrink Posted October 7, 2015 Root Admin Posted October 7, 2015 Get that one BB at the top out of the mag. Get something long and pointy and push down the second of those two jammed BBs - I've had this before with the GHK mags (very, very rarely). Dunno what causes it - I guess it's just tolerances.
Neilbarker Posted October 7, 2015 Author Posted October 7, 2015 Okay pushed it down, it reset, fired two bbs and done it Again though there's not one rattling about an more it's just stuck. I wanna open it and take the bbs out and try different ones but in not sure if that'd stop me being able to send it back as it just got here yesterday
Root Admin proffrink Posted October 7, 2015 Root Admin Posted October 7, 2015 Are you pushing down the one behind it? If you just push down the one ontop then it's not going to do anything. It's the way they're offset that's jamming them - you need to disrupt that in some way.
Neilbarker Posted October 7, 2015 Author Posted October 7, 2015 Yeah pushing it right down and it came back up and the bbs fed right for two more shots then it jammed again
straffham Posted October 7, 2015 Posted October 7, 2015 strange that the gun cycles and fires gas yet the BBs are jammed in the feed lips. Sounds like for whatever reason the mag feed lip is slightly low relative to the feed nozzle, otherwise the air nozzle should either feed a BB or stop against a jammed BB in the mag (or the mag follower)?
Neilbarker Posted October 7, 2015 Author Posted October 7, 2015 They're not in the feed lips I can see inside the feed lips and there's bbs stuck beside each other under them but no bbs actually in them
Root Admin proffrink Posted October 7, 2015 Root Admin Posted October 7, 2015 Hm, sounds like the mag itself has warped then and is maybe been crushed a millimetre at that one spot - as soon as two BBs travel through they get jammed. Is the BB/feed channel metal or plastic? If metal you should be able to just push it out a bit with a screwdriver and the right amount of leverage (if it's not too far below the feed lips); if plastic then it shouldn't be warping in the first place. It may not even be entirely obvious from the exterior as it only needs to be a very small difference. Maybe shine a light down and see if you can see if it's visibly narrower at that one spot?
K@rl Posted October 8, 2015 Posted October 8, 2015 Can I just ask. Is the gun we? Did the mags come with the weapon? I know that some mags don't get on with some brands of gun. More common in electric but could be the problem.
