I just acquired a three barrel Browning Special Sporting Clays. I only got three choke tubes with each barrel. I'd like to fill in the gaps. The chokes I am looking for are Invector - below is a pic of what I'm looking for. Extended chokes are preferred. 20 ga - Sk, IC, LtMod, Mod, ImpMod, and Full 28 ga - Same as above . 410 bore - Same as above.
