I haven't seen the VEPR mags and how they fit/lock-up. Are they much different than any other AK based mags, or are they like the Saiga mags? I see where Atlantic has 20 round 7.62x54R VEPR mags for sale. Says they're US made. Dutigaf, have you seen these? I know we were talking on another thread about trying to have someone manufacture some hi-cap PSL mags. I wonder if these would fit, or could fit with minor modification??
