Seems like lack of track record is here in the US since it has only been here since the begining of the year. It been produced since 2007 and the testing it went through by the Germans is impressive. I saw that a trigger kit is now available which takes it down to about 3.5 pound pull. I was impressed by the guy on you tube that did a long term test. Over 10,000 rounds and never cleaned. He highly reccomended it.
