12GA XL Bore Choke

Description

This is the tube for 12 gauge Rizzinis bored to the XL profile — the largest of the three 12 gauge bore diameters. XL Bore barrels are threaded and bored differently from Plus and standard Rizzini barrels, so the profile has to match: a Plus tube will not seat or pattern correctly in an XL Bore barrel. The profile is stamped on any tube that came with the gun and is listed on your spec card.

Choose flush if you want the tube to finish level with the muzzle — clean lines, nothing to catch in cover, nothing to change the look of the barrel. Choose extended for a knurled tube that stands proud of the muzzle, so you can change it by hand between stands without reaching for a wrench.

Seven constrictions are available, from Cylinder for slugs and close birds through to Full for late-season pass shooting. Each tube is turned from bar stock, finished in black oxide, bench-checked against the barrel profile it is cut for, and rated for steel shot.

Sold individually. Not sure which constriction you’re holding? Count the notches on the rim — one notch is Full, five is Cylinder — or read the code stamped beside them.
