Tim, no sir, this gun has a 20" Contoured Barrel with fixed Slug Choke. It does not come with a muzzle brake, as suggested below.

Timothy, yes, I watched an unboxing video of this shotgun and it includes three chokes, modified, full and cylinder choke. Hope this helps.

Timothy, no Sir, it comes with at contoured barrel with muzzle brake as pictured here. classicfirearms.com/rocki-tk113-traditional-12-sng-shot-shotgun/

I would contact customer service for that information. The product description for this UPC# is all over the place. Some say it has a slug choke, other said it comes with 5 different types of chokes included, and another site said this come preinstalled with muzzle brake.
