When it comes blending an extension and when it comes back from Mark Larson it looked wonderful, and still does.
However if it is a heavily used gun the epoxy coat will take its nicks and the line where the extension meets the buttstock it will become visable over time in the right light if you know it is there.
I see the use of an extension a good interim step on an otherwise unshootable gun. On a field grade gun whether blended or not it is an excellent long term option.
On a high grade gun it is an option that allows you to shoot the gun until you decide if you like it enough to restock it. Moreover given the waiting time for some craftsmen the extension is the only option until they can do the job. Further Mark Larson's blending wile not a permanent solution for a high grade gun is one I took and I am very happy with the result.
