Your pic shows Large Shank and Standard Shank but you say we need the small shank nut. So the small shank is different than the ones in the pic?Be sure you get the right one, the right size shank and thread pitch and not a Remage barrel nut which is a savage style barrel nut used to fit a Remington 700 receiver.
There’s large and small shank barrel nuts & receivers.
These barrels should accept small shank barrel nuts.
You guys looking for a donor rifle, make sure you know what your looking at.
