WE Glock Mag Jam

[CerialKiller]

Hello World,

I like to tech my AEGs and after buying a lower quality G32C and constantly screwing with it to get it to work I eventually decided I hate teching GBBPs. So I said "F" it and went out and bought a higher quality WE G33 Advance. The G33 advance came with a mag and I bought another WE G17 mag (G33 Advance uses G17 mags) from Toronto Airsoft. The mag that came with the gun will jam maybe once in the first 20ish rounds and then I don't even bother trying to shoot the last 4 rounds as it jams after each shot. The spare mag I got from Toronto Airsoft won't fire more than 1-2 rounds before jamming, even when fully stacked. I'm shooting 0.3 Bioval Biodegrade-able BBs (tried .25 Bio, still jams). I know its not the gun because even when I flick the rounds out with my thumb (no gun) both mags still jam. I tried loading the BB wells with silicon oil (and I mean soak) but they still jam. I'm not a moron, I do know how to stack a double stack mag. My P.O.S. G32C didn't have this problem. My best guess is the gap where the pin is on the side of the mag that locks back the slide when empty is a little too big so the BB's are getting trapped in it. Is this a known issue with WE mags? Am I just an unlucky P.O.S. that nobody loves (least of all WE)? Is there any way to fix it? I can see people shooting WE Glocks no problem on YouTube and I hate every last one of them for it. Also somehow I just got a lawsuit from Glock for using their name and I haven't even hit post yet. Those guys are good.

Any help would be greatly appreciated. Suggesting suicide is not help.

Your post is super confusing so i'll try to make some general suggestions.

1. Field strip, clean any gunk (grease, debris, etc) from the slide and lower frame.
2. If the MAGAZINES are not feeding (the bb's are loaded but do not penetrate the feed lips such that they can escape the hole) remove the base plate and feed lips to expose the spring. Clean the inside (sides, bottom, spring itself) of any grease, debris, etc.
It's highly likely that the bb, bb guide, and debris, is getting caught on the side preventing feeding.

3. Make sure that the magazines have sufficient gas because this is necessary for the function of blowback to re chamber the bb.

Sorry for the confusion. I was trying to provide as much detail and narrow down the possibilities as much as possible. I may have also been venting a little. The issue is exactly how you describe in comment 2; BB's jam right at the bottom of the plastic fitting that has the feed lips on it. I'll try cleaning the feet out but these mags are both brand new (like haven't left my living room yet kinda new) so I'm doubting they will be dirty?

Thanks for your help. I'll post tomorrow to let you know how it goes.

I had the same problem with my TM mags.. same bb's.. I took the feed lip off and filed the opening a bit to smooth it out.. didn't really help much.. then I cleaned it and this that and the other thing and it didn't help.. honestly it looked like the bb's would not stagger in the mag but almost sit side by side.. soo I eventually got mad enough and put two pieces of wood either side the mag, put it in a vise and squeezed the sides of the mag together... bbs stopped going side by side and staggered properly.. however on randomly decided days the bbs will still stick occasionally. weirdest thing

[CerialKiller]

I just came back to post results and I actually did the exact same thing as apilar with the exact same results. I got a better look at what was going on as well. So for those of you keeping track, I pulled the top off, cleaned out this inside with some soapy water and a q-tip, dried it, re-oiled it with silicone oil. I noticed the arm that pushes the BBs up the well was broken off on the mag that came with the gun so I glued it back on using cyanoacrylate (strong) glue. I also filed down the transition between the mag and the top plastic "finger" piece. Maybe a little better but still jams. I think I figured out why though. Poor design. The top part has a inverted "V" shape to funnel the BBs. When the BBs are funneled the uppermost one must rotate on top of the second BB. If the well is too wide the angle between the BB is too steep and it causes the upward force to become an outward force against the mag causing the jam. Similar to why a CAM works in climbing. Thus, if WE simply took out a few BBs and narrowed the BB well, I bet this would not be an issue. I'm not sure why I don't see more G17 mag horror stories from WE. I believe apilar has the right approach with crushing the mag with a vice. I bet the BBs stick more on a hot day because BIO BBs will have a higher coefficient of friction between each-other as they heat up. Guess I'm going to crush my original mag and return the Toronto Airsoft one (I suspect something else is wrong with the Toronto Airsoft one as well). Maybe they will have one there that will work for me.

Disclaimer: If anyone from Toronto Airsoft is reading this I only F***ed with the original mag.

apilar do you have any advice/lessons learned the hard way W.R.T crushing your glock mag?

Thank You apilar and RainyEyes for you help,
-Tom... I mean...CerialKiller.. yeah....

Update:

Re-reading apilar's post I noticed he mentioned he used the same BBs. I grabbed a pack of old VA 0.25g BBs (non-bio) I had and loaded them up. No jams. Shot perfectly. Now non-bio's would have less friction than Bio BBs. Does anyone have a Glock that they use bio BBs in (caveat: it must feed properly)? Which brand do you use?

In all fairness when I called Toronto Airsoft the guy I talked to suggested Bio BBs could be causing an issue but since I need Bios as I play almost exclusively outdoors I largely ignored him.... because I'm an idiot. So well played Toronto Airsoft, well played indeed *swirling rum in crystal*.

Thanks,

How old are your bios? Have you tried other brands? I've had elite force bios feed up to 37 RPS in one of my aegs without issues. Aeg midcaps will use a similar double stacking method to your glock mags.

[apilar]

No hard lessons learned. I took it slow and squeezed a bit at a time sooo worked out not too bad for me at all.

The bios are pretty fresh maybe a week old tops, kept in sealed bag at around 20-21 degrees (room temp) Havnt tested it much lately. Been keepin with the old faithful 1911's

Have you tried different brands of bios? I hate using bios since they rarely work in high performance guns. When I find a brand that works I stick to it, since experimentation with ones that don't work lead to catastrophic piston failure in my AEGs.

Just got Bios from Airsoft GI maybe a month ago. Kept in cool, dark, life-sucking environment (my office). Found some really old (2 year+) Madbull .25 bios. They ran better but still jammed. I did some research and everyone seems to like the Elite Force Bios so I'll go pick some up and try them next week. No one is open in the area who sells Elite force over the long weekend. My friends all shoot Bioval. I feel your pain, at this point catastrophic piston failure is becoming part of my daily routine on game days.

Thanks again for the help guys, really appreciate it,

This actually shouldn't happen because the bb's are spheres so that would mean that if they were pushing outward, they would rotate to accommodate the exit. This would mean that it's a problem with the material the bio bb's are made with that causes too much friction against other bb's or the walls of the mag.

What kind of catastrophic piston failure are you talking about? Bio BBs jamming can cause piston failure.

This sounds more like a recoil spring issue than anything else.
If your recoil spring cant pull your entire slide assembley, logically what occurs should be a BB jam. Especially if your shooting at the last legs of your gas magazine. You need good blowback to reach an equal opposite force of return. Sort of.

Try a strengthened spring. Maybe?

Are these piston failures gas or AEG? I had assumed they were AEG piston failures.

I actually re-read OPs original post.
I got it all WRONG!!!

lol.

It's a magazine issue where the bb cant stack properly either because the stacking chamber is too wide or and bb's are too..small(?)

actually, I used to have this issue with 50 rounders. Switch the bb's to BB Bastards andnever looked back. Instant fix. I used to buy those crappy Velocity Arms bb that TA sold. they were shit.

anyways,
disregard everything i said.
carry on. nothing to see here. lol.
