"50 rnd drum mag for HK 91,G3 rifles"

Cliff Sparks on 1/11/2013 9:56:01 PMVerified

Overall Product Rating:


I would have to give it a 3 rating because of the major amount of retro fitting I had to do and the fact that I have not tested it at the range yet. I did get the mag to fit my Cetme Sporter very well and the bolt takes rounds to the chamber and ejects the live rounds like it should. We will see how thing's go at the range.I'm thinking it will work just fine, Thank's


"Very nice addition and a great fit for my HK91"

Jost got the drum today. Well made and fit my HK91 tightly. Having 50 rounds of .308 has made a huge difference in my range outings. HK parts.net shipped fast and communication was superb. I would highly recommend this product for all HK91 owners.


"Just what I was looking for. HK G8 drum is awesome"

Wes Cragen on 2/12/2010 8:02:49 PM

Overall Product Rating:


I have dealt with HKParts many times before but was a little hesitant about this item but figured lifetime warranty...Adam's reputaion...what the hell I will give it a try. I cannot put the thing down and the gun I once shot very little is now my favorite toy as I can do LONG dumps with ease and a total croud pleaser to boot. Way to go HKPARTS for offering a truly innovative alternative to the 20 round G3 magazine. By the way...I got my drum in 2 days HKParts shipping is amazing as always.

This drum is awesome! It makes me want to get a sear. It comes with great directions and fits perfectly in my ptr-91. Now I want another!


"HK91 50 rd drum on a Century Cetme"

Tom Sprehe on 12/7/2012 6:37:30 PMVerified

Overall Product Rating:


Because the Drum would not fit my Century Cetme I rounded the front corners of the drum to fit the magazine well of Cetme. Now it locked up. I fired half the drum yesterday and it worked great. I also put graphite on the first few rounds. Nice made product.


"50/50 chance you'll need to be 'handy' with tools"

THOMAS MOSS on 6/4/2011 1:26:23 PMVerified

You know, 4.5 lbs isn't much when you're talking about a sack of dog food, but hanging halfway up your 91 it will make a believer out of you. Front and rear halves are easily tightened (mine had a little slop in it) and when it's buttoned up, it's a very solid unit. Some are loose, some are tight, some are juuuust right, and mine was tight. Wouldn't-go-in tight. Deft Dremel-tool work removing metal at the base, then sanding off the black coating made it drop-free. Work in little bits, don't over... More details
