"More than a year in the making! I love this thing.

I use this with my Thompson M1A1 by Tokyo Marui. I'm fully aware that the M1A1 Thompson was incapable of accepting drum mags in real life, but this is airsoft.

This drum took a backseat in the back of my closet. I used it probably once in the first year I had it. I treated it like a novelty and, as such, it spent very little time with me on the field.

There are two reasons I've only used this on the field once: it's unwieldy to sling a weapon with a drum mag this size sticking out from it's side and it's heavy.

This is full metal and weighs like it is. There is a full quarter pound of BBs inside of this (when using .25g rounds), the weight of the metal drum and then the weight of the metal gun. It's a lot of weight.

The most amazing thing about this, though, it feeds absolutely flawlessly in my Marui M1A1. Firing at either 825RPM or 930RPM, it feeds very well with no dry fires until the winding it spent. Each winding of the magazine probably feeds about 100 rounds out of the magazine, making it extremely efficient compared to standard hicap stick mags (usually around 30 rounds per winding, IME).

If you've got a Thompson of any type and you want that absolutely monster look to it, get this thing! I love mine. If you primary your and want extra firepower and wow, this is what you want.

"This drum is great for my king arms holds a huge capacity and great durability justs dont step on it like I did with my 170pound [email protected]$$. A small plastic piece came off but it works fine and the piece is pointless.of you are considering buying this, do long as you love pinning enemies down with constant storms of BBs
