· SHOP / CHOKES ·
Every Rizzini choke is turned and finished to the same tolerances as the barrels it screws into. Start with your gauge — then pick the bore profile your gun is cut for. Flush or extended and the constriction are chosen on the product page.
Not sure what you own? Read the notches below.

· IDENTIFY WHAT YOU HAVE ·
Pull the tube out of the barrel and look at the rim. The filed notches tell you the constriction in about ten seconds.
Notches are filed into the rim of the tube. Fewer notches means more constriction: one notch is the tightest.
Skeet tubes are often marked SK; Light Modified and Extra Full carry an LM or XF stamp rather than a notch count.
Still unsure? Send us the serial number and a photo of the tube rim and we will tell you exactly what it takes. Contact support →
· 12 GAUGE BODY TYPES ·
The notches tell you the constriction; the body tells you the family. Lay your tube next to this and match the length, the threads, and where the knurling sits.
XL Bore and Plus tubes are cut for the larger bore profiles — a Standard flush tube will not interchange. If you are unsure which barrels you have, send us the serial number. Contact support →
