Let us talk about the foreign companies. For Germany there are five companies that make ARs. Heckler and Koch and Sig also make ARs. The three dedicated AR companies are...
Oberland arms. They have a black label AR which are made of different brand parts to keep it cheap. They start around 1200 euros. They have higher quality which start around 1900 euros.
Schmeisser. Most of my friends own a Schmeisser. Better quality then the Oberland Arms.
Hera Arms. My choice in AR. Their ARs are called 15th Dynamic. Named after the 15th Roman legion that guarded Germany. Rifles start around 2000 dollars. Also better then Oberland Arms. Mine was also tuned by Pro Tuning, and I chose the color.
