Brian, according to IverJohnson web site, the IJ500 Includes 3 internally threaded choke tubes (Full, Improved Modified, and Modified). Have a great day!

I'd honestly contact Iver Johnson cause some websites are saying this has 4 chokes, some are saying 5, so I'd contact them at 321-636-3377 or email them at service@iverjohnsonarms.com sorry couldn't give a definite answer but hope this helps.

Brian, there are (4) included Beretta Mobil Chokes and Choke Wrench - Includes: MobilChoke Style Chokes: Improved Cylinder, Modified, Improved Modified, Full. Cheers and stay safe!

comes with 4 chokes "Includes:
MobilChoke Style Chokes: Improved Cylinder, Modified, Improved Modified, Full" but other chokes are easy to find in the Beretta Mobilchokes system

Yes, this includes 5 mobile chokes. Includes full, improved modified, modified, cylinder and improved cylinder. Hope this helps.
