It has been a long time since, but I built my first rifle from one of their "Tennessee Mountain" pattern stocks. I was very pleased with the service and the value. Dick Greensides was great to deal with. The inletting was nicely done and I was happy with it.
As with any pre-inlet kits, some of their patterns may come inlet for hardware or locks that you might not prefer. Make sure you have an idea of what parts you really want on it, and if there are any parts you want to subsitute, Pecatonica will work with you to substitute in some cases when they can (locks and barrels) or if not (i.e. hardware), have them leave that part un-inlet so you can use the part of your chosing.
For mine, I had them leave all the hardware (including the sideplate) un-inlet so I could use a set of hardware from Myron Carlson. They also offered an option for a more appropriate style lock (L&R Manton) for a 1830 Tennessee rifle than the large Siler that the kit came with standard so I went with that too. If swamped barrels were an option offered at the time, I would have gone with that too, moreso for better wrist architecture than anything - but the 40 caliber GM barrel it came with worked out great so no complaints. They are now offering swamped barrels as an option for some of their patterns. Ask about locks - they may work with you.
