Indian Creek Stevens help

[Southernson13]

So unless I'm missing something the 301t has win choke threads which are the same as invector threads? Indian Creek has the 041 model(Stevens 301) and the 046 model (brown inv, moss500, winchok...Etc). Can I not out the 046 model in my 301?? I've been after a 390 choke for over a year and they do not exist on the internet. If I can use the 046 model I can find one today. Annoyed as hell with IC customer service. They do not respond to email and never answer the phone.

In the 301 you need the .0041 model choke
