Barrels are marked Optima for optima choke, Optima HP for Optima HP, Never seen a optima + . So that one I don't know But it should be.Do Beretta barrels indicate which series of Optima chokes?
I know the treads are the same. This is a bad thing IMO. Gave up telling a guy at my club. He is running optima chokes in an Optima HP barrel. So far no apparent damage.I do know one thing, some of them, with a little effort, will interchange with disastrous consequences.
Could you not just ask the person that you purchased the gun from? They kept the chokes for a reason. They must expect to use them. Or is something else going on?I recently purchased a second-hand AL391 Urika, supposedly built in 2005. Unfortunately, it did not come with any chokes so I need to buy them.
