    WE Gas Blow Back M4A1 Carbine

    Sounds like the white plastic collar on the guide rod housing has slipped forward. Push it back/glue it in place.

    Thanks for the reply - I've just unscrewed the feed lip on a couple of mags and there is no rubber seal below on either, just the square rubber block which seals to the brass cylinder. I have hopefully just resolved the brass cylinder/mag issue by unscrewing the delta ring and removing/replacing the barrel assembly. It seems for some reason part #114 (inner barrel nut) was not sat flush in the upper receiver?! Strange. The mags now lock into place much easier, but I still have the same problem with feeding/burst fire A quick pull and release of the trigger on semi auto 'fires' 2 or 3 times, only the first BB comes out at speed, any others will queue up somewhere inside and either roll out or fire out all at once. I've followed 3vi1-D4n's advice and removed excess material from part #117 by turning it inside out and sanded using a dremel griding bit at low speed. When out of the chamber it allows a BB to pass through with relative ease, but enough to prevent it rolling out of the barrel. When #117 is put back into the chamber, it is a little tighter and takes a push to pass a BB through. Unfortunately it has not cured the problem though so the cause must be elsewhere.

    Thanks 3vil1-D4n for the parts list, I'll definately look into modifying part 117 and getting hold of a CWI trigger set. In the mean time, I've done a little more investigation now that I've had a few hours to sit down and look at it. Strangely, I've noticed that it has become very difficult to get magazines to lock into place in the magwell - it requires too much force. By removing the bolt carrier and watching through the ejection port as I insert a mag, I noticed that the rubber gas seal is touching the brass cylinder about 1mm before the mag catch 'locks' the magazine (this happens with all 6 of my magazines) which means a lot of force is put on the brass cylinder to fully insert a mag, which isn't good - I can see the brass cylinder being forced upwards. I've checked and the brass cylinder appears to be perfectly straight. With the cylinder removed the mags lock into place easily. Has anybody experienced this problem before? A search on various forums only reveals the M4/Scar mag incompatibility issue due to the raised gas seal on the scar mags, but mine are definately M4 mags (the gas seal barely protrudes from the plastic guide on top of the mag). Again, any help much appreciated!

    Really starting to lose my patience with this money-pit of a gun! Can anyone help with the problems below please? Today at a skirmish the gun misfed/misfired right from the word go. It fired one round, then started 'collecting' BBs and would spit 6 or so out at a time (even with the hop completely 'off'). I tried various quality brands of BBs and the same happened with all of them, and it happened with all 6 of my magazines. Just as the problem seemed to cure itself, the bolt carrier then jammed back half into the buffer tube (about half an inch of the bolt carrier was visible from the ejection port) and I could not get it to move forward or backward even with some help, hence I couldn't open the receiver. I had to unscrew the buffer tube and 'wiggle' the bolt carrier around for ages until finally pulling it out. I re-lubed everything and replaced the bolt carrier and buffer tube and now I have two-round burst fire on semi auto!! If anyone can help or point me in the right direction I'd really appreciate it! In terms of internal upgrades this M4 just has the NPAS kit, stinger hop kit and the 6.02 chrome barrel. I am running on Co2 if that makes any difference.

    I used the rubber, paper shim then I got some 200gsm card/paper and cut a tiny square approx 1.5mm x 1.5mm and placed that on top of the paper shim. It turned my stinger hop from completely useless to fairly good (although it is still no match for a standard TM AEG hop setup).
