Retay Choke Notches

The notches on Retay chokes are used to quickly identify choke tube size without having to remove the choke. Retay chokes closely follow the sizing and markings of Benelli Mobil chokes. The chart below lists the common Retay choke notches and the size of choke.

Choke markings come in a wide range of variations, but their meaning across the spectrum is largely the same. Manufacturers can use notching/serration systems, color coding, alpha naming schemes, and color banding to indicate the diameter of the choke tube. This is done for quick verification without having to remove the choke from the gun in most cases.

Marking	Choke Size
I	Full
II	Improved Modified
III	Modified
IIII	Improved Cylinder
V	Cylinder

See this chart for Retay choke diameters.

Notches found on Retay chokes indicate 1 notch is Full, 2 notches is Improved Modified, 3 notches is Modified, 4 notches is Improved Cylinder, and 5 notches is Cylinder.
