CYMA 100rd Extended Magazine for CM030 / 18C AEP Pistol

"This is a good magazine for the money and feeds very well, but beware of the feeding lips, they wear out quickly, and I had to cut the internal mag spring in half in order to get the mag to hold bbs. I would suggest a TM hicap which also holds more bbs than this.

"It's a real hit and miss with these mags. While they're cheap and effective, some of them will have the feed lips wear out and you'll only be able to carry around half of the intended capacity. The spring is strong to feed down to the last BB. But I've had games where I hear a racheting sound only to see my tracer BBs squirt out if I rub the magazine the wrong way. I bought 4 of these together and I found that I had to toss 2 of them because mid-match I realized I lost a lot of ammo along the way. This was after several hundred rounds being fed into them.

Later I thought I should try this again, so I got another 4, but I decided to be a little more cautious rather than just going out of the box and playing with them immediately. I tested all of them to full capacity and decided to stress test them by jiggling them around, running around the house with my full airsoft loadout as a simulated CQB game, and gently tapping the base if i can upset the strong spring. Sure enough none of them passed the test as I had to get the vacuum cleaner to pick up after my mess I caused. I didn't return them since I didn't want someone else to get these lemons, so I tossed them into the DC recycle bin. ...also losing half of my .20g EF bbs.

I ended up buying the Marui brand extended magazine from elsewhere. I took the hit in shipping but I'm not leaving a BB trail of where I was during CQB matches at Tactical Airsoft Manassas.

"I bought TWO of these for my TM Glock 18C AEP.

They both DO NOT WORK for the TM.

However, they will work 110% in the CYMA knock-off 18c's.
Just to be sure , we retested them: Again, NO-GO in TM's but works great in the CYMA.

Additional notes: they are lightweight and pretty much all plastic.
You get what you paid for.---I had to trade both of mine to get one TM brand Hicap.

I think its not the product, but the advertizing for the product that needs to be changed. Should read : Not for use in TM 18C AEP.

Because of that, i gave it a 2 out of 5.

"Pulled it out of the package and loaded around 40 rounds and as soon as I pulled the loader away they all shot out. Will not hold bb’s.
