I've owned my Yankee for over 2 years and I love it. I've never shot a quality AR-15 like the Yankee and i still haven't. I bought it from a friend in the Coast Guard for $700. It only had 200 rounds shot out of it before I bought it. It took about 1000 rounds to get the "machine burrs" out of the trigger assembly, but it works great now. I've shot about 2500 rounds total through it, and i was wondering if anyone had a problem with their Yankee and about how many rounds shot through it before it went wrong. I just found out they only come with a 1 year warranty, I probably should be stoked it lasted this long with no problems (except for the "burrs").
