Hatsan 20ga Shotguns (Could be 1 of 4 different choke systems, Please Call if not exactly sure)

Interchanges with Carlson’s Huglu style threads if threads are at the top of the choke (Flush choke is 2″ long w/ threads at the top of the choke) . Marked V1 – likely Huglu

If threads are at bottoms of the choke possibly interchanges with Carlson’s  Remington Choke (Rem Choke) (Flush choke is 2″ long w/threads at bottom) marked as V3. Some V3 are proprietary  and will not work.

Call with your factory choke in hand to help identify further.
