From TR Imports "Super-strong door-buster style muzzle brake unscrews, allowing barrel to accept optional extended choke tubes (ideal for Turkey hunting)." they do not say what type chokes it takes I suggest you ask them about the availability of chokes phone 817 750-2291 or email info@trimports.com

OK, I apologize Travis. and Randy Just goes to show one can't always just accept the information they find on the internet .. especially YouTube. I accept randy i's response and explanation. He does his research, unlike some others here who accept everything YouTube has to offer as truth. .

James those sets all say "Extended choke tubes for all Silver Eagle semi auto and pump 12 gauges ******except SE122, SE122TAC, and RZ17TAC." (***** added) Not a single choke on the TRI page says it for the SE122

Rick I don't think the SE122 used the Huglu chokes I think these choke screw ON not In I think they are like the old Lyman choke system Travis Please check this before you buy

Travis, you can pick up extended Choke Tubes directly from TR Imports : trimports.com/product-category/parts/choke-tubes/

These shotguns use Huglu thread pattern choke tubes. Specialty after market chokes available from: Trulock, Carlson’s, Patternmaster, and Briley.
