DrJekyll Posted March 1, 2017 Report Share Posted March 1, 2017 A nice clean semi auto Hk21 built on a ptr91 receiver, mostly german parts. It has a Michael machines trunion installed, the cocking notch has been reinforced and moved forward for the 21E buttstock and buffer. It also has a 21E rear bipod weldment and carry handle. Everything cycles nice and smooth, very little wear, only about 1000 rounds through it. It sports a manganese park with HK black duracoat over it. Bore is bright and shiny, included are 4 100 round DM belts with starter tabs. Ready for a registered pack All NFA rules apply $7200.00 Shipped to you FFL Link to comment Share on other sites More sharing options...
