That is I project worthy of the effort. I always thought the M1 & M2 conversions made the nicest .22 Hornet sporters ever.
I seem to remember reading that the Winchester M54/M70 .22 Hornet magazine box assembly was used for some of the conversions but I'm not positive that G&H did that. I suppose a Winchester .22 Hornet magazine box assembly could be found with some effort.
Personally, I would prefer that system to a detachable clip unless it was something Like a Sako L46 that didn't protrude below the trigger guard.
