Did a little actual looking after making last post. The procedure I stated is actually for a Mod 11 Rem. Browning instructions say to never fire the gun without the bronze friction piece next to the bbl ring. The M11 has an outside bevel on one end of "Ring" with the internal bevel in other. The A5 ring is flat on the one end. On the M11 for use with the Cutts the ring is turned with outside bevel fitting into bbl ring, & bronze piece placed down against receiver. I appoligize for the mix up, going to have to quit going from memory.
