I really want to finish up my savage 10 + boyds featherweight thumbhole stock. I started out with the barreled receiver and bought a stock, not knowing that it was the detachable magazine version which requires the surround.

Is there a good source for the metal surround? I know I could go with an AICS type, however I really would like the savage-style, that way I could get a few higher-capacity SSS 9rd magazines that are compatible with it and use it in both this setup & one of my other magazine fed, metal surround rifles.
