The ERMA SR100 is a high dollar tactical rifle that is used by some elite units (Germany’s GSG9 being one of them). This is a very high quality weapon that is designed to be one of the most accurate rifles in existence, and it is indeed extremely accurate, with groups coming in the sub .25 MOA. The rifle has some unique features, like a 60 degree rotating bolt, a unique mounting system for the action, etc. The stock is of laminate wood, which while more weather resistant then standard wood, its not as good as synthetic.
The rifle has a good following, is used by some elite units, and has a good pedigree. The $9000 USD price tag is pricey, but to some its worth it.
Update: Rumor has it that production has stopped on this rifle.
