Thank you. I knew that of course but did not think of it when I did that quick reply to the OP's question. In some cases the threaded shank might still have to be shortened but tou would not have to be concerned about it protuding into the barrel like on rib-less guns.
hrobalabama1 the thread size you could likely look up on the web for the Browning but the others might not be so easy. Many US makers used 3-56 thread size but there are many that use other sizes.
