If it can be done with an uzi, why not a Mac? Beta c-mag

[Mr. Blue]

100rd beta mag in an Uzi SMG:

NOW WHERE CAN I GETS ME ONE FOR AN M11/9!
And how much? Somebodys got to have one...

 

[yzfchet]

1) Get a MAX-11 upper with the Dual Feed modification for your M11/9.

2) Determine whether the Colt 9mm or MP5 9mm Betaco C-Mag has the closest feed tower dimensions to the Lage-modified Suomi 9mm magazine.

3) Buy the appropriate C-Mag and cut a Lage-modified Suomi mag so that it becomes the feed tower for the selected C-Mag. Install the new feed tower onto the C-Mag.

4) Load it up and blast away.

Better hurry - someone else is bound to be working on this as we speak.

i think the the angled design of the mag is making it difficult to do they are not box type like the uzi and colt mags that the beta was designed to work with. I have been working on a suomi drum conversion it is not going easy it will take some time to get to work perfect i am starting to think it is not worth the time to do it

M-11 drums

I saw this thread and wanted to chime in. I have worked on a lot of these suomi drums (working on three now) and receive about 5-10 calls a week on them as well. I have yet to see one work well. One problem i believe is that the suomi M31 gun runs at a lower rate of fire than that of an M-11 and even if you slow it down with an upper, you will still find that it doesn't work well. Some of the best fabricators and gun smiths have given them a shot at working and have encountered similar results. I know Richard Lage has spent some time working on them and has had not so great results as well. Though I bet he may someday make his own drum and make it work. The Suomi drums seem to work if you shoot them ghetto style on its side and hit it every few rounds to prevent misfeeds. A beta version may work better but it will take some money and some testing to get it right.

When Lage said that he would be producing his DF for the Max-11 slowfire , I thought a Beta mag was on the way.

So....when are you guys going to start working on it?

I just finished my own suomi drum mag, and it runs fine. Although I had to hand fit the blank rounds, and modify the feed tower from double to single stack. There is no angle to the tower from the drum on my mag. I believe the angle creates more downward pressure on the mag along with seating issues. Weight is also a factor when trying getting the mag to feed correctly. The drum mag had to be "tweeked" several times to run flawlessly. Alot of time and ammo at the range, but worth it.

there's been threads discussing this in the past-- there's a guy that will build one for ya.

Heh, I was thinking "I know there was some one on here that makes them, goes by CAG or something like that..." Thanks for the link

That wasn't even 100 rounds. I counted like 78. olice

When Richard Lage built the DF upper I loaned him my Beta mag so he could make a tower. Quite a while later he gave my mag back to me and told me he never got the Suomi tower to function.

Excuse my noobyness, but what is a DF?

EDIT: Nevermind. I figured out that it stand for double feed. So, what is the advantage of a DF setup and what mags do you use?

I've got one for my Walther MPL made by C&S. It has the angled feed tower as I donated the M-10 magazine and gave them the Suomi drum as well. Mine works perfectly and was done right. The angled magazine has nothing to do with the performance. Knowing HOW to do it is everything. I've had the drum now for over 12 years. Still works as good as the day they made it.

The Suomis run at 900 rpm, not that big a difference and well within a slowed down Mac's reach. I've had plenty of drums that have worked reliably. I have just recently converted an M1A1 West Hurley Thompson to 9 mm and use the Suomi drum and it works great.

I'd also like to know how in the world you are holding it "ghetto" style and still managing to hit it every few rounds to prevent misfeeds. You'd have to hit it like every 1/10th of a second to get it every few rounds. I'd like to watch that... got a video? I bet not.

I have a CS drum (M11/9) too, and just like yours, mine runs perfect. I also have an Autowerks 380 (M11A1) drum that runs equally well. A couple of you guys are acting like you just reinvented the wheel or sumthing. You're about 15 years behind the curve.

Grunbroker, subguns, sturm all have the CS drums come up for a few hundred bucks. That makes the most sense to me.

My SCA drums are doing well as paperweights & ashtrays, so buyer beware

edit: my post was not directed at shattered, it was directed at everyone who thinks they have just built the first functioning drum mag.
Sorry shattered, it looked like I was talking to you. I wasn't.

 

[coyle311]

I have C&S drums for my uzi, mk760, and M11 and all function perfectly. I know they're more expensive, but they run, and that makes them worth the extra for me.

hah... I didn't take it that way at all. You did good buying a C&S drum... when you did. Now everyone wants to know the secrets of C&S.
