Hatsan semi auto mag extension thread

S&J should probably sticky the info, it's pretty far back in their forums...

Unscrew the end cap of your mag tube, and look at the threads, particularly whether they extend all the way to the forestock.

If it looks like this:

Then it's the older style, "Tyoe 1" extension you need.

If it looks like this:
hatsan%20long%20thread_zpshxianit0.jpg

Then it's the new style, "Type 2" extension you need.

If you're unsure, unscrew the mag cap, take a picture, and post it in their dealer sub-forum. They're very good about responding and quite helpful.

p.s. I've bought a number of parts off them (including the extension for my Hatsan MPA), and have nothing but positive things to say about them.
