Very nicely done.
Quite similar to some of the Westley Richards threaded takedowns although concealing the release in the forend is nice as long as it won't shoot loose! I take it that is not possible as you must push the release screw in prior to rotating it, correct?
Would be nice to have a trap grip cap with the release driver housed inside. Just a suggestion.
