    HK91 / G3 22lr conversion ?

    I recently got a 22lr conversion for an HK91 (G3K clone) that I also recently purchased.
    I tested them both out today and they worked great. However, I’ve been spoiled with the lightning grip loader and I seen that black dog machine sells an adapter for the HK91 / G3 22lr conversion; their adapter uses their Uzi 22 mags. After looking at the photos of the BDM Uzi 22 mags, they appear to be really close to BDM/Lage 22 mags (other than: side mag catch and curvature).
    Link to their adapter:

    Does anyone know if you can use a Lage 22 mags with BDM’s HK91 22 adapter?
    I think it might work but I will need to add a side mag catch. Any information will be greatly appreciated.



    Thanks.

    The Lage .22 mags are not compatible with the BDM’s HK91 adapter. The Lage mag body is too wide.

    People seem to have mixed success with the BDM .22 uzi mag adapters with their HK91 .22 conversions. https://www.hkpro.com/threads/tsc-4-.../#post-3939607

    Does anyone knows how to increase the BDM .22 uzi mag spring tension?

    Thank you for the information and the link.

    I’ve used a straw to increase the spring tension in my Lage 22 mags. I’ve cut them to about 3/8ths of an inch or so and they’ve helped spring tension. I’ve got probably 30k rounds down range with my lage kits. After awhile, I started getting problems and this mod had helped. People have also printed spacers.

    I posted this video awhile ago and it will explain what I did (1:20 Mark).
