"This Echo1 Fat Mag is *amazing* in combat. Grab 3 of these and you effectively become a support assault gunner. It is made of metal and fits into any gun that takes standard M4 mags. Well, except for mine, I had to stick a few layers of duct tape to the hole where the magazine locks so it wouldnít sag and not feed. Easy fix, no problem. No one else has been complaining about it so Iím just gonna guess my mag was weird. Winding is pretty easy, a little stiffer than JGís M4 mags but wonít imprint your fingers with plastic gear marks. These things hold a whopping 850 rounds, compared to standard 300 rounds, for only about $8 more. Thatís 550 more rounds, almost two more magazines worth! If you run through ammo or simply need a new mag, buy one of these. Theyíre worth it.

Feeds well, easy winding
850 ROUNDS!!
Made of metal
Fits any M4

May need some duct tape to keep mag in place (no one else is complaining, I may have gotten a slightly defective mag)
Does stretch your mag pouches a bit

Overall: Great mag, buying two more. If you need a mag, just grab one of these, itís got ammo almost worth 3 mags, for only about $8 more!

"Got this for my KWA M16 which was $285
It is the only mag I need to carry.

Metal body (solid)
Fits better than the mag that came with the gun
Fits in my M249 which is broken );
Fits in G&G raider m4
Feeds fine with the 11.1 lipo in M16
Barely have to reload
I love going prone and this mag allows me to do so
No holes in bottom of mag for dirt to get in

Cons: spinning the winding wheel all the time gets
annoying, but better than needing to reload
