I have the Archangel Precision with the adjustable cheek riser and buttplate. The only negative is that it required fitting to get the action in. I went slow with the patience of a Saint to make sure I didn't over do it. It was a real PITA. The action fits tightly like a glove, which is what you want for accuracy. Once the action was fitted to the stock the magazines were a really tight fit in the mag well. Instead of hogging the well out I used 120 grit sandpaper on a flat surface and thinned the magazines out. Equal strokes both sides, and measuring with calipers. It was a real PITA. Now the mags fall free with gravity, and the rifle is really accurate. Fitting was a real PITA (did I mention that before?) but well worth it to me.
The adjustment wheels for the cheek and butt come with two springs and detent balls, and were quite hard for me to adjust. I took both adjustments apart and removed one spring and ball from each. The adjustments are still strong and positive, but easier for an average human being to operate.
I like this stock a lot because it works well, after doing the fitting and mods, and when my daughter wants to shoot with me it is easy enough to adjust for her. I also like that I can adjust it for shooting off a bench/prone/etc. I have a full custom build in it and the accuracy is as good as with any other custom stock I have for it. It's not a light stock, but it's not really heavy, either.
I mentioned the work that I had to do to the stock to get the action to fit, which was a real PITA (did I mention that already?), just in case it may be a deal breaker for you. I have no experience with the Luth Chassis, so can't comment on it. Hope this helps.
