It was new when I bought it and I have put maybe 200 rounds through it. Of those very few rounds I didn't have a single problem. So while it is far from extensive testing, I don't foresee you having any problems with this gun. I sighted it in at 25 yards, and it kept consistent groups in the bullseye. I am sure it shoots better than I do, and would need a good scope to start pushing the limits of it's accuracy. Ask away with any questions and I will do my best to answer them in a timely manner. I am located half-way between Seattle and Portland and would prefer FTF, but would consider shipping. I am not interested in any trades at this time, as this is going to fund my next project piece that I already have.
