Dynamic Arms Research is a high-end German manufacturer of AR-15 rifles. DAR manufacture their own uppers, lowers, rails and muzzle brakes. They use Lothar Walther barrels and Magpul stocks and magazines.   They are chambered in .223 Rem., .300 Whisper and 6.8mm SPC. The rifles sell for around €3000 (nearly $3,900 at todays exchange rate).  These photos were taken at IWA ’13.
