to accept the new made uppers for different calibers?
Made a new upper with a .450 Bushmaster, for Zone 3 in Michigan.
would like to swap the 5.56 barrel onto a new upper from the HBAR [large hole] to the .25 hole.
Thanks.

Know anyone into model railroading? Those guys make tiny little stuff.
This outfit has the bushings to fit large pin uppers to standard small pin lowers. And what you want.

Now I understand why that Match Target upper was cheap.
Just spoke to them. In tomorrow's mail.
