Winchoke Question

[jblackburn]

Recently got a model 1300 (never had one before), I want to make sure I understand this correctly:

Winchoke, Invector, and Mossberg 500 (AccuChoke??) are all the same, correct?

Invector+ is different?

Most chokes that will fit the 1300 will be Invector, but some may be Winchoke. Invector+ will not work. In my search for the right 1300 choke, I ended up with an IC .660. Patterns well with Hevi 7's and LB 6's. 270's with the 7's and 220's with the LB 6's. Good luck!

Thanks for the info.  Any idea about the moss berg 500 chokes?  Are they also invector threads?

Yes
