I've had one for 10 or so years a search with daewoo dr200 will get what you need with google. It's a korean made rifle. Ak piston rod, ar trigger group, ar magazine, fn fal gas adjust systen for sorry ammo and h& k style sight. Very dependable, acurassy 2 moa or better, mine shoots .72" 5 shot with reloads and no modifications, 1.3" with malaysian fmj. Reliability has been reported as excellent in combat situations. Very scarce, you may see one at a gun show every now and then. Last I saw they were running $900-$1500. Check gunsamerica.com they may have some for a reference price. There is also a dr400 in 7.62x39mm.
