SabinoCarl,
My rifle was from the original product run in 2014. Seems a lot of the rifles that have issues have components from that era. CA gave me a new barrel, new trigger assembly and new stock. I noticed a minor hairline fracture in the forearm before I sent it back and I included that in my report. Seems they thought it was worth replacing. Didn't get much of an explanation as to what they found that was out of spec but happy that they just took care of it. They also shot it and provided a detailed report. I didn't have to plead with them to do any of this, they just stepped up and did the right thing and did it quickly. Call them and detail your issues, they'll take care of you.
I did not go through break in on the new setup. There are lots of opinions out there as to whether or not that makes a difference on a rifle. I did find that my groups really started to tighten up around the 500 shot mark. I shoot hand loads now and have an effective range to 850 yards. The rifle is capable of more, no doubt.
Hope that helps.
