The chokes that came with my new SA-08 have no writing on the that I can see. The only thing they have are notches cut in the end. There were three tubes with 2, 3, and 4 notches respectively. Does anyone know how to identify these? The manual says nothing. After shooting a few rounds of skeet today, I suspect the 4 notch is a full choke based on how the pigeons reacted to hits, but I'm unsure.

There's always the old wise tale that says a dime should not be able to fit down a full choke, but will the others, but that's not necessarily true. Each gun manufacturer will make their chokes with a slightly different inside diameter. To be sure which marking is which choke, try getting some calipers for measuring inside diameter and see which one is the tightest.

Did you find out which is which? I just bought an SA-08 upland. Mine came with the 4 notch choke installed. I assumed it was the modified, but now think that it's the IC choke and the other two are full and modified.

the four notch is I.C. the two notch is FULL that leaves the three notch to be MOD
