SBE II has the new crio system, cryogenicly cured barrel and choke tubes, so will the aftermarket choke tubes for the orginal SBE work?

Good question, I was wondering the very same thing.

I bet the larger after market manufacturers will step up and put out something that works. I have an older SBE that works well as a turkey gun. I like the lightness and fast shooting that it provides. I did have to have some work done on it to make shooting 3 1/2" mags manageable. I understand the new model has a much tamer kick due to new technology. Perhaps I need to trade.

I have one now, comp and choke. I had to call them.

i use a gobblin thunder in my nova 12ga it worked 40-45 ydss on my bird
im gonna pattern alil mor ethis yr
only shot a few last yr

The SBEII choke is the same as the Beretta Optima Plus so there should be plenty out there to choose from. Nitro and Pure Gold make them for sure.
