This rifle performed well at the range with no jams after 200 rounds. also it was snowing heavily at the range that day and some moisture inevitably got in the chamber and around the bolt but it still performed great. There are some things I did not like. For Example, the magazine release catches on something sometimes causing it to scrape on  its way back, also the gun shipped with a different quad rail than advertised. The one on the website is twice as long,also the magazines that it came with appeared heavily used. On a lighter note, the stock is excellent(very sturdy design) and the trigger has a very smooth operation. Also, I love the Yankee Hill sights. Lastly the ergo gip is great as well, it feels great in your hand and has a gripy rubberized texture.    
I give it a four only because it shipped with a shorter quad rail than advertised.
