ICS 2500rd Adaptive Drum Magazine for Airsoft AEG Rifles w/ M4 Mag Adapter (Color: Black)

"So, I've had this C-mag for a few years, and I gotta say, it's amazing. If your gun can handle it, and your field prohibits full auto on non-support weapons, this will give you the semi-auto firepower you need to be aggressive without the weight of a whole LMG. You can keep a stream of plastic going down-range with 2500 rounds of attitude.

HIGHLY recommended for those who don't mind a couple extra pounds of weight hanging off their gun.

Pros:
- VERY high capacity
- Feeding issues are very minor (skips a BB every so often, but with how many you can put out, it's hardly a problem)
- Looks sick as hell B)

Cons:
- Heavy
- A pain in the butt to stow
- Changing its battery in the middle of a firefight is stressful lol

"This drum mag works wonders! It's a little loose fitting (but most mags will be) but fed well into my G&G M4. The pressure switch works well and has a sticky side that can be attached to the grip of the gun for easy access. Also kept up with the ROF really well. The battery compartment is a tad small, but other than that I've no complaints. Be warned that it will add some weight to your gun. Combined with the grenade launcher it makes my M4 more than a little hefty. Which trust me, makes a difference when in the field for extended periods of time.
Pros:
can switch out the adapter to fit other guns.
Feeds well into my rifle.
Doesn't get in the way of my arm much.
You'll look like B.A.!

Cons:
Battery compartment is a little small.
Magazine wobbles a little.

"Good feeding drum mag. I use a modify hop up in a g&p lower reciever body. Feeds good for guns that shoot around 20-25 rps. My gun shoots 33 rps and it unwinds itself but I could turn down my rof too. Over great magazine for suppressing.

"I have had this for about 2 months now, and I have no complaints at all.
I use mine in a VFC SCAR, and it doesn't move at all.
Overall: perfect fit, perfect feed, and perfect construction. Best Drum mag I have ever had.

"I got this C-mag so I could be able to properly play support using my VFC Avalon Calibur, and this magazine has definitely allowed me to do such. It feeds nicely, if a little bit slow for how I tend to use it. It holds a lot of ammo, and I've so far only needed to replace the battery once or twice after taking it to a total of about five games.

Only reason this is getting 4/5 stars is that it's a bit wobbly in my magwell, which makes me feel a bit uneasy that it's going to fall out. Thankfully, it has yet to fall out. So until then, it will stay at its current rating.

I would highly recommend this C-mag to anyone like me that wants to turn their gun into a support weapon.

"These things suck. Honestly, horrible.

I bought two for my Krytac LMG and I got through the first day of my op without issue, the next day, I had the first box mag fail within 20 minutes of starting the evo. So, I bought a 2nd, just in case something like this happened. I put it in, and total feeding failure on that one too withing 5 minutes.

Loaded a regular m4 mag into my krytac, feeds just fine, borrowed my friends box mag, feeds just fine.

Bottom line, I had two of these crazy expensive mags fail with minutes of each other. Absolutely terrible product. Do not buy.
