Browning chokes are regulated to a nominal bore of .742, Blaser chokes are regulated to a nominal bore of .732-.735,with all due respect Your chokes may fit in a Browning but are not properly regulated for the Browning invector plus bore and could cause catastrophic damage to the gun and or injury to the user !!
Good to know, I had been improperly informed from a dealer that they were safely interchangeable. Thanks for the heads up.
