rsvpiper Posted January 15, 2020 Share Posted January 15, 2020 Over the break I had a quick play with my new WE M16. I was quite cold around 8 degrees C put red gas in the mag at first it fires ok but then bb's start coming out the ejection port! Is is fair to assume this is just a cold weather issue? 20200111_121811.mp4 Link to comment Share on other sites More sharing options...
RYoung22 Posted January 15, 2020 Share Posted January 15, 2020 My guess would be a feeding issue like lining up the feed lips on the magazine with the groove / track that pushes the bb into the hop-up unit / cylinder (just a guess). My only experience with cold weather gas issues have really been my magazines using more gas and being less efficient than they do in the summer.

Guest Yukarin Posted January 15, 2020 Share Posted January 15, 2020 Only occurs in full auto? How about indoors when the mags are warmer? Do BBs still come out of the barrel at the same time as they come out of the ejection port? Link to comment Share on other sites More sharing options...
EDcase Posted January 15, 2020 Share Posted January 15, 2020 Hmm, just waiting for mine to arrive 😏 Could be an alignment issue with the nozzle or the magazine feed lips might need wearing in a bit (holding BB's too tight) Yes, check indoors with warmer temps to eliminate that possibility. Check the internals for signs of wear (fresh metal exposed) to make sure fit tolerances are OK Link to comment Share on other sites More sharing options...
EvilMonkee Posted January 15, 2020 Share Posted January 15, 2020 Either a feed issue or a cycle speed issue. Doesnt appear to be gas cool down related. Counter intuitive as it seems try it with normal green gas as well. Try better BBs too. Strange that it seems to feed fine in semi - hence why I mention the cycle speed.

Guest DrAlexanderTobacco Posted January 15, 2020 Share Posted January 15, 2020 Might be the retention catch in the mag being loose, combined with the recoil shaking things around. I have a few old gbbr mags where if you give them a solid whack, the catch comes loose and some BBs are pushed out by the spring Do you have another mag to test? It would help with troubleshooting even if my suggestion isn't the root cause. Link to comment Share on other sites More sharing options...

Agreed, there could be a possibility that the catch on the bottom of the nozzle that feeds the bbs into the chamber is hitting the feed lips and knocking them loose?

Might be possible but haven't heard of that happening before. Waiting for OP's answer to my questions, but generally, even with red or black gas, full auto isn't really usable in the winter for GBBRs and as a result bolt bounce or double feeds may be causing his issue.

Very true it’s a rare thing to happen, to be fair all the suggestions in this post are very possible issues/solutions - Like you say, more info surrounding the issue is probably needed Link to comment Share on other sites More sharing options...
rsvpiper Posted January 15, 2020 Author Share Posted January 15, 2020 Ok folk put two other mags through the gun from inside the house still kicking bb's out on auto but only after 2-3 bursts. Some pictures of the bolt Link to comment Share on other sites More sharing options...
Guest Yukarin Posted January 15, 2020 Share Posted January 15, 2020 Nozzle looks completely fine, to confirm, this only happens on full auto? Were you using red gas indoors? Also BBs are coming out of the barrel at the same time as them being kicked out the ejection port? Link to comment Share on other sites More sharing options...

Yes only happening on full auto, don't see it seems to be double feeding! Did use red gas yes, I'll not get chance to do anything now till tomorrow but from memory it did the same on green in the house shooting onto the garden Link to comment Share on other sites More sharing options...
RYoung22 Posted January 15, 2020 Share Posted January 15, 2020 Might be a strange solution but is it fitted with an NPAS valve? I’ve known the valve to get stuck or close and essentially not fire any gas to the barrel (sends near 100% gas rearward to cycle the bolt) & ends up feeding 2/3 bb’s without firing, jams & throws them out of the extraction port (sounds strange I know but I’ve had a friends gun with this problem) however this wouldn’t explain why it works on semi and not on auto Link to comment Share on other sites More sharing options...
EDcase Posted January 15, 2020 Share Posted January 15, 2020 rsvpiper: Have you disassembled it and cleaned everything? New guns straight from factory are not the cleanest. Hard to see but looking at the first photo at full res it does look like there are a few dings in the top part of the hood where the fake lock lugs are. Don't think it will be the cause and shouldn't affect performance but keep an eye on that area to make sure it doesn't get worse. Link to comment Share on other sites More sharing options...

Over the weekend stripped and cleaned the bolt oiled it up, green gas in mag and it fires faultless! First 3 rnd single shot then 3 full auto bursts without a hitch 👍 Link to comment Share on other sites More sharing options...
EDcase Posted January 20, 2020 Share Posted January 20, 2020 Cool 👍 Can't wait to get mine. Duno if I'll use it in a game tho. Mags are so expensive & only 20rds for the shorties and 30 for the Stanags. I'd need to spend more on the mags than the gun... Link to comment Share on other sites More sharing options...

Ain't that the truth, just have to be a bit more disciplined with the trigger finger, got a great deal on the gun and mags from anareus.eu even free shipping on anything over €150! winner winner chicken dinner Link to comment Share on other sites More sharing options...
EDcase Posted January 23, 2020 Share Posted January 23, 2020 Yeah, I might get three or four 30rd mags and see how it goes. Not heard of Anareus before I got THIS one for £277 including delivery... ...BUT it seems that ParcelFarce have lost it 😡 UPDATE: Tracking now says 'Sorted' 😏 4 days to get from Taiwan to UK 10 days to get through customs 🤣 Link to comment Share on other sites More sharing options...

EDcase Posted January 25, 2020 Share Posted January 25, 2020 Well, turns out customs want £73.99 which makes the total £351 so I'll just let it go back and maybe get one from Anareus instead. Even though the magazines at Anareus are good price, I'm kinda bummed that I'd have to spend quite a bit more to actually skirmish 🙄 From what several people have told me, I would need around 7 mags for a short game (only 230 rounds including the supplied mag) which would cost a total £537 😖 That's the reality of GBBR's I guess Link to comment Share on other sites More sharing options...
