Hatsan Escort is a clone of... Complete the sentence

[Tokarev]

Still trying to figure it out, so today I measured its choke thread and found that it is approximately 1/2" in diameter and 27 TPI ACME pattern turned down to approximately .480".
They look very much like Rem 410 chokes, the only difference being Rem has UNF 60 degree thread.
Does any other US brand shotgun come with 1/2-27 ACME threaded chokes?

[Cap'n Morgan]

I would be surprised if the threads on a Turkish made shotgun were imperial. More likely, it's a proprietary thread or an ISO trapezoidal thread - e.g. TR13x1 or similar nomenclature.

When they clone, they also clone the threads. They do not match any metric thread step.

Beretta Mobil chokes will fit the Hatsan Escort

Pietro:

If you have access to Beretta chokes in 410, could you check their thread pattern?
