steel tiger Posted September 6, 2011 Report Share Posted September 6, 2011 Hey guys, Over the last month I have had some major issues with both my M240 box mags. They seem to be jamming every couple a hundred rounds. They apear to be jamming down in the feeding mechanism. Only seems to happen when the box mag has over 1000 rounds in it. If I just put a couple hand fulls of ammo in it feed fine. When it james the little lever on top the wheel needs to pulled back or pushed forward to clear the jam. Most times it is jamed hard and I have to dump all the ammo out, then pull the lever back in the opposite way the feed system spins. This is because the feed wheel seems very stiff and jammed. Has any one had any problems like this or have any ideas how to fix it? Echo 1 has been less then helpful so far. Link to post Share on other sites
ertgunner Posted September 6, 2011 Report Share Posted September 6, 2011 don't have a 240 but it is common with support guns. its most likely just dirty, take it apart and clean it. Link to post Share on other sites

steel tiger Posted September 6, 2011 Author Report Share Posted September 6, 2011 I have tried 4 different types of name brand ammo. It had been shooting fine it just started this problem with the latest box mag last week. The other box mag started doing it two months ago so I ordered the replacement. Now they are both screwed up.

Jimmypie Posted September 6, 2011 Report Share Posted September 6, 2011 im not all that familiar with this gun but what type of battery powers the box mag, off the gun or seperate? if off of the gun is the rof running much quicker than the box mag can feed? or vice versa? I had similar problems with an old CA 249,balancing the rof with feed. Link to post Share on other sites

ertgunner Posted September 7, 2011 Report Share Posted September 7, 2011 If it is like my 60 box it can be the connector coming off of the spring, to fix that you would just hold the spring and turn the base of the connector. Link to post Share on other sites
