hk91 sub caliber kit

  1. HK PARTS AND ACCESSORIES FOR SALE
    WTS HkG3 (will work in Hk91) .22 / .308 conversion kit. Has barrel insert, fitted box, bolt group, and two twenty round mags. It’s original from the 70s but what makes this one unique is it was reworked by HK in 1990 and has a little dated metal tag secured inside the box. As far as I know it...
