HK G3 / HK 91 22LR magazine review (Video)

[KickStand]

I was sent an H&K G3 / H&K 91 .22 LR magazine for testing and review. Functionally, the magazine performed flawlessly during live-fire testing and feeding was consistent and reliable throughout, with no malfunctions or failures. The magazine has an approximate capacity of 33 rounds and maintains proper fit and lockup in the rifle. Furthermore, the magazine is fairly lightweight; at this time, I have just over 500 rounds through the magazine and it still looks great and performs like new.

The test unit featured a two-tone color scheme, but production models will be a single uniform color.
Overall, this magazine offers reliable performance, nice lock up and is constructed well, making it a suitable choice for anyone running a .22 LR conversion in an H&K pattern rifle.

Very cool! I look forward to hearing more about these.

I assume it’s a 3D printed mag? Are the feed lips metal?

The feedlips are not metal but they are replaceable and appear to be really strong.
Hopefully, K2 will chime in.

How about making some MP5 .22lr Conversion magazines.

Hi All,

The magazines are printed, modular and are all plastic. There may be steel feed lips in the future but not planned right now. The feed lips are similar to other plastic feed lips I've used and have gotten 5000-7000 rounds before they were unreliable. (It took 18 months to do that testing.) The 91/G3 22 magazines can have their feed lips replaced by removing 4 screws. The feed lips, being a small part, are very affordable.

MG34_Dan: I hear you. Maybe someday. It would be nice to have higher capacity magazines for the MP5 22 conversion.

Enjoy,

K2

Hi All,

Here is a typical magazine (33 rounds) vs the HK version (20 rounds). I started with plastic 20 round magazines as the objective was a lighter mag belt in competition. Everyone wanted bigger and now they are 33 rounds. While the 33 round magazines fit in the typical Bundeswehr 2 magazine pouch (top flap open), the Bundeswehr MP2 Flecktarn pouch (no dividers, flap open) has a bit more depth (but only 1 mag fits in the pouch).

Enjoy,

K2

I will buy a bunch when you finalize the design. Thanks for doing this

Hi K2 ,I will buy some of these when you are ready .
I really enjoy the g-3 conversion kit and mine has been quite reliable.
Hope to hear from you soon.

what would really be cool is for someone to manufacture a clone of the bazooka brothers hk91 adapter to attach and feed an E&L--165-225--0r--275rd 22 drum. there used to be vids on here--i think harrissr maybe--thats where I learned of them and was able to buy the adapter before they ceased manufacture (believe he passed away)

 

[unclebear]

I would buy the drum adaptor in a heartbeat !

 

[Alaska_Shooter]

I’m interested in mags when they’re ready. You re-motivated me to dig out the conversion kits. 😀

Thanks!

Also interested in some 33 rounders.

Hi All,

Thanks to those on the forum that have been helping out. To date the "functions great" score on HK manufactured firearms (F/A & S/A) is 100% great (3 for 3). The testing on a non-HK 91 gun indicates additional work is needed as the magazine doesn't fit the mag-well (w/o sanding), doesn't lock-up, and doesn't feed.

I'm contacting my local friends to get non-HK test guns to continue development.

Enjoy,

K2

maybe i can get a mag dump video posted between turkey day and x-mas with the 51

Man! If only that adapter was for an MP5!!!

American 180 adapter!

Guys, Mak91 absolutely hit a grand slam with this one! Some of you might remember that we gave this a shot a few years back and I ended up throwing in the towel. Thankfully, Mak91 didn’t stop and stuck with it, did what he does best, and delivered something awesome! This would be great for all...

if he can print an adapter for an m16/ar15 one can be printed for an mp5
