Not Intuative

Well made strong industrail grade fixture however, its up to the user to figure out how to use it The supplied piece of paper passed off as a user guide/ instruction set is useless. For better all round general usability get the series one and forget this one unless you intend to us it for hanmer hooks (its best use). A 90 degree precison marked grid extending beyond the hammer work would be a nice enc if only a few degres of + /- reference wer ever used. It appears you have to establish the original factory plane of reference to start from. Very hard on small surfaces and very trial and error.

Good Jig

I gave it 3 stars, because it halfway rocks, and is halfway horrible. Directions are terrible. You need specific stones to use it. However, once you have it right, it's the bomb. I asked Power Custom for assistance, and they were all over it. They were even willing to set it up for me! Honestly, this thing is beast. Just know you're going to have to be EXTREMELY patient in setting it up, and again, you have to get the stones, other than that I love it. See? Half love, half disdain. 3 stars.

Not for most people

The Pro's: 1. A well made machine 2. Precise 3. Plenty of adjustments The Con's 1. The instructions are terrible 2. There is no list of what guns the universl jig works on. The only tell you a 10/22 and Ruger single action. 3. After going crosseyed trying to figure out how to use the fixture and jig, I emailed Power Custom for help. It's been a week and still no response. I did eventually figure the jig out, but the instructions were almost no help and I couldn't find a picture of an assembled fixture/jig on the internet anywhere. A color picture would have helped more than anything else. The jig does work, but has a really steep learning curve. I'm really pleased with my second 10/22 trigger and am ready to try my AR-15 next. I wish Power Custom would answer my email about what all guns this universal fixture works with... The bottom line is: If you're not really mechanically inclined, don't buy this. Also, don't expect the manufacturer to support you after the sale. Also, know that you have to use the special stones that are only for the Series II fixture. No other stones will work, though another vendor sells a steel/sandpaper kit that might work OK. Other than those negatives, it's a well made, well designed product that does exactly what it's supposed to do.
