I have one and can only relate my experience. Bought it last month and fired about 400 rounds through it. Two problems w/ it. Muzzle break would actually be pushed off from the recoil, landing appx 15 ft in front of f/l. They promptly sent me a new one w/ a stronger spring.Then the bolt fractured and broke, sounding like a misfire. I sent it in last monday and it should have arrived in AZ on friday last week, still havn't gotten response yet. The accuracy is there, the carbon components are going to be fine, the bolt design needs to be re-engineered and w/ possibly different material, titanium poss, to keep it light. Otherwise they should go to moly/steel mix.
