I could not have been happier with the quality of this kit. The inletting was very precise. For me, if something fit a little tight it was easier to file off just a few thousandths of metal than work on the wood. Time wise which always seems to be a question - I timed the build very closely. If all I wanted to,do is slap it together and go out and shoot it I could have done that in about five hours. I took my time ,enjoying the process, and have forty hours total in. I took all metal and wood finishing to 300 grit. The flat filing on the barrel was, actually, very satisfying and the first two or three sides took about thirty minutes each, then I got faster and the remaining sides took just twenty each. It came out great.
