That Tristar built off the beretta A400 sure is nice. The vipermax
Everything I read says it's built in Turkey by Armsan. Are they using Beretta parts?
I know it's a little off topic but, I wouldn't be surprised. Stoeger semis and pump guns are - or at least were some time ago - made by Vursan in Turkey. Beretta made the barrels and shipped them Turkey for final assembly on the Stoegers. Vursan made the Benelli, Beretta and Franchi receivers and shipped those to Italy for final assembly. Beretta bought the company and renamed it. So basically Beretta, Benelli, Franchi and Stoger are all made by Beretta. They all use the same gas inertia system
At one time they were slightly different dimensionally but a lot of the internal parts would interchange. Comparing the Benelli and Franchi 20ga I had in a while back with a buddies Stoger, I couldn't tell any difference other than external lines making stocks and fore arms specific to each brand/model
I have worked on Benelli, Beretta and Franchi shotguns that wouldn't cycle, but I've never had a Stoger come in that had cycling issues.
