Theoretically do-able,......

totally impractical, in choice of platform

What, pray tell keeps the "Adaptor" from getting flung out on the ground, as you cycle the action as a "single Shot" ?..remove the regular extractor?

LEADING issues ?

....slinging undersized .22 lr lead bullets down a .223 bore
( with a GAS PORT ),....and expecting to just remove the "Adaptor" ,....go back to Jacketed ( no effect on zero anticipated?) ?

I can build the thing,....but really advise you not to run it.

sounds like a REAL DOG.
