View Full Version : Reliability of drum mags

06-01-2009, 3:49 PM
I know they are not available for sale here, but I have heard nothing but warnings regarding the reliability of drum mags, esp the AK ones. Can anyone share their personal experience about this?

That hasn't been my experience; I have a pile of steel 75rd drums for my Kalashnikovs and they run like clockwork.

I used the BetaC mags with CAR-15s and M4s on and off over my time in the Army and they were mostly problematic (let alone ridiculously heavy). A Ready Mag setup is much wiser. As for AKs, also heavy but not as unreliable from what I've experienced.

I've never heard anything about reliability issues with AK drums. I do know from personal experience that the Chinese ones work great.

My beta mags for my ar's have never jammed and they hold 100rnds as for the AK drums....I have a 75rnd drum that is romanian that you load 1 rnd at a time (sucks) but it too has never jammed, don't know about the snail type drums for mini 14's. So in my opinion they are reliable!

...not personal experience, but was at Burro Cyn range several years back and as I was leaving these guys show up with AK and drum mag. Asked them if it was okay if I watch...long story short... 15 minutes later they couldn't get the thing to work. Not sure if it didn't fit right or cartridges wouldn't feed.

I have a stack of MWG 90rd drums for my AR type rifles and for the most part they work very well. There were some problems with the earlier version's feed towers that were made of a plastic that allowed the feed lips to flex too much leading to malfunctions. The later ones with updated feed towers were actually pretty reliable, the only issue I had with them is that they were tedious to load (loaded from the top) but a cartridge guide and plunger was included with each drum to facilitate loading.

I've used some old Chinese 75 round drums.
Reminded me of a wind up toy.
Load bullets, wind it up, shoot about 20-30 rounds, wind it up some more.

Which drums were around before the ban???

Everything, basically. The 94 Fed "crime" bill halted the importation and manufacture of additional high cap mags (over 10 rds) but it wasn't until 2000 when Californians were prohibited from buying any additional high cap (standard cap, actually) mags. Between 1994 and 2000, high cap prices were sky high because the numbers were effectively frozen (until the Fed crime bill sunsetted in 2004).

what? i think you are supposed to give it about 9 clicks then all 75 rounds feed fine the design turns a double lip alternating feed magazine into a 1 lipper so it gets alot of use

but with the design of the beta-c it doesnt have bolt hold open but after 100 one dryfire at the end is ok i suppose

all the promag drums are garbage they made one for the

AK 75 rounders and the Chinese 100 rounders work great.

The version the Chinese built for AR's using the basic combloc design works well.

BetaC's work for recreational use only. I've seen them fail.

My preban Chinese 75 and 100's work, period. There are new Chinese copies from Bulgaria that have just been imported. You can use those to repair your preban Chinese 75rnd drums. Chinese mags have been banned from importation since 1998.

i would say it would be opposite from what you heard. drums of quality function great and no problems.

My Chinese 75 round ak drum always runs like a champ. My ar 100 round (converted from an ak drum) is a useless pile of crap.
