A&K M249 box mag 

This really works!!! Had a feeding issue for a good few months now tried everything but this took me less than 3 minutes and now it works better than new!! Thanks mate you're a legend!! Carlos (uk)

Man 8 year and this video still usefull! Thanks a lot my box works great now!

Thank you very much, mine came like this from the factory and your video saved me precious hours !

Dude, you're a legend! this cured my M249 feed issues. Thanks!

I have a feeding problem with my drum mag too. First ideea was that the bb's are not ok (even bb's are made by G&G - and I didn't have untill now problems), but after I wach this video - I will fix it as you did. Thank you!

Thanks for the info man, hopefully this helps me. I'm running the A&K MK46

Thank you so much I would have never thought of this

Omg this really works, you are a GOD!!!

Wow can't believe you got an m249, you guys are really getting into airsoft, everbody must be decked out with gear n guns

if you do it too much you can always use very small washers or even make some

too much filing I'm guessing would stress the gears or crack the shell, but idk. just a heads up. looking forward to buying the gun though.

Bruh the fact that a&k can't do this is amazing.

if you do to much just add some shimming...

Thanks, glad it helped. :)

Would this still work even though this m249 i have isnt exactly factory new i just bought it off my buddy and he said hes never had a feeding issue i will be sure to try this

I have a question, my auto feed works perfectly fine on this box mag, but when I use it on sound mode, it doesn't pickup the sound of the gearbox and refuses to load? Is it a lose wire? Or did something break inside? I opened it up and everything looked fine, but it is a bit of an annoyance to put it on auto feed the whole time

Great video, thanks!!

Will this work for the m249 sack box mag?

Dang this really worked? I mkight actually buy an m249 now

What about pkm any ideas

Where did you get your gun case?

Well just spent around 400$ on a M249, first days everything fine and now this happened to me, tried what you did but no success, money wasted.

¿What is "A&K"? P.D. Read the description.

i could hear him just fine on a laptop at half volume

Any chance u know how much you filed off?

Lol, not the kids...their just starting to build up their guns... Haha, but I got 2 m249 now.. :) r you guys still playing?

My box mag works perfect! But my gun only shoots for 5 or 10 seconds then it won’t shoot at all then it will randomly shoot again once I pull the trigger I kinda feel stupid for buying this dang gun

this did not help my 2014 box mag. just saying for anyone else.

Sk8, i'll make a better video WITH a tripod so you can see the entire process.
