Brown Precision is a brand I have used with good results. My first synthetic, back in the early 80's was made by Garrett Acculite Company. They are out of business now, but were similar in quaity to Brown.
I've had 1 Bansner, High Tech Specialties. I think they have potential, but I didn't keep the rifle it was on long enough to get a fair assessment.
If you don't mind a heavy synthetic the B&C Medalist are good enough. Just as good as H-S Precision, but a lot cheaper. I've had 1 B&C Ti. Couldn't give me another. They are overpriced, aren't particularly light and are poorly constructed. They are simply an injected molded stock with chopped fiberglass filler which actually weakens the stock. There is nothing in them to give them any strength. They do a good job of external finish which makes them look good, but most of the tupperware stocks are stronger.
This gun was not dropped, or run over by a truck. Just shot off a bench. 30-06 recoil was enough to snap the stock. Laminated layers of fiberglass cloth or an aluminum bedding block would have prevented this.
