Choke tubes for Derya Turkish O/U Shotgun

[elch jager]

My daughter got a Derya 20 ga as a gift from a friend. It came with 5 tubes... her careless father borrowed it for an upland hunt and he somehow lost the 3 unused tubes...

We are managing now with the modified in the upper and full in the lower, but would like to dial it in a bit more for our local duck shooting.

Does anyone know what brand chokes might be interchangeable? I do have calipers and can measure the ones we have, although I don't have a gauge for the threads...

Believe they use Mobil chokes...Beretta/Benelli MC. Take one into the store with you....try not to lose that one.

I think they are Benelli.
