If you get another that's not up to par, but you like the gun, tear it down and fix it up. It's not very hard to do, and you will probably like your rifle more when you know what's going on inside, and know it is right. And it's fun learning how to do it yourself, and helping others get their stuff working top notch. At least it is for me.
Even if you get a good one, it probably could still be better with a little tinkering.
I've bought a lot of things that "should have worked out of the box" that I liked enough that I fixed the issues instead of returning it. And I haven't regretted it yet. Guns, cars, electronics, tools, you name it.
Just trying to look at the other side of the coin. Thumbs up for the review.
