I contacted Apline Gunworks about their light weight, super adjustable stocks a few months ago. He had to redesign it to accomidate my Surgeon 591 action, and Fed-Ex delivered my prize two days ago. Instulation was easy with only a couple allen wrenches need for full adjustments. The fit and construction of the stock is very precise and the adjustments are very fast and easy. Overall I am very happy with this upgrade and I plan on having future builds with this stock. I will be writing a full review, with more pics, and submitting it very soon.
