For comrades with AK and Saiga in .223.
There is new and ground-breaking player, Definitive Arms, LLC.
Since I rarely ever use AK mags in .223 (most of them are junk, as compared to well-defined 7.62 and 5.45 versions), might as well make it permanent.
And they designed true BHO, AR-style, watch video.
I feel it's like .223 AK vasectomy: you do it once and then have fun for as long as your barrel can take it.
And no worries about poorly behaving offsprings (low quality .223 AK mags).
Stick a good stuff in and rock'n'roll!
