I am doing some research and studding on building my first long range rifle and was hoping for some advice. It will mostly be for target shooting at the farm/local range and possibly may try some PRS in the future. I have been checking around and reading a lot of articles on the subject. My idea so far would be for a Defiance Tactical action, MPA chassis, Jewel trigger, and ether a Bartlein or Krieger barrel. I have not had a chance to actually hold a MPA chassis in my hands so any thoughts good or bad on them would be appreciated. I have shot a jewel and timmy trigger and liked the jewel better, but thoughts are welcome. Also has anybody had a rifle built by MPA? How was the quality/customer service? Not sure if I am asking the right questions but please educate me in what I should be looking for in a rifle builder as well. So far I have talked to GA, SAC,MPA, and String Bean all of them seem knowledgeable and nice, but MPA seems to be the most reasonable on price.
