Just picked up a used Affinity Sporting and I'm looking for a case to carry it.  I'm trying to find something like a 'discrete bag' to carry the shotgun broken down (and strapped in place via Velcro is the goal) with probably a pocket for chokes, wrench, snake, etc. Does anyone have any suggestions for me?  It's a 30 inch barrel so I'm figuring a 32in case would be perfect.

Also, does anyone have a shotgun using the Benelli Mobil choke tube system?  I'm looking at aftermarket extended tubes and really don't know what I should be looking for in brands and such.  Are there any from which I need to steer clear?

Look HERE for a good assortment of choke tubes

Carlson's are decent chokes, and competitively priced.  

I also like Ballistic Specialties and Briley.

I came across the Carlson tubes, they seemed like a very good value but was interested in first hand experience.  Thanks! I will have to check all of these out... any pros or cons between makers that jump out to you?

How dialed in do you want to be?  Get your bore measured. Then order the exact chokes you need based on your actual bore diameter from Ballistic Specialties.

I am not knocking you or your gun but Carlson will probably be just fine.  If I want an extra tube for field use I will grab a Carlson, otherwise I prefer BS and Briley.  Beretta, Benelli, Franchi, all the same thing really and their OEM tubes are better then most.  Jus get yourself set up with the chokes you don't have yet and go from there.

Ask yourself this, are you OK with spending 300-$400 just on tubes?

I have this case and it is a great deal.

That's pretty cool!
