Hi Jeffrey, yes sir, this comes with 3 Benelli/Mobil style choke tubes, Full, Modified, & Improved Cylinder. You want rifled (foster) slugs and you will get best accuracy with the improved cylinder choke. Do not shoot slugs through a full choke.
Stay safe & have a great day!

Hi Jeffrey and welcome. Yes Sir. Foster type slugs will favor Improved Cylinder or Modified Chokes depending on the individual firearm. Do not fire slugs through Full Chokes. Just take a few minutes and see which choke your shotgun gives the best accuracy with at a modest distance. Full Chokes tend to have too much restriction and deforms the slug when it exits and ruins accuracy. Cheers and stay safe!

yes you can shoot slugs out of this shotgun for best accuacry use more open chokes like IC and Mod also use foster (rifled) type slugs while tey would be safe sabot type slugs are made for riffled barrels/chokesand are not accurate through a smoothbore for the ultimate accuracy ues a sabot through a rifled choke like this one choketube.com/choke-tube-style/beretta-benelli-mobil-12-gauge-rifled-choke-tubes/
