H&R choke tube question

[birddog2]

Picked up an H&R auto excell 12 ga for a little nothing. Only came with a full choke, anyone know of any other tubes that will work? H&R site says any common american 1"x 32" thread. Anyone have any feedback on this model? Once I got all the rust off seemed like a decent gun for a $100.00
Thanks

You can look at Briley, Trulock, and Carlson's for possible chokes

I don't know about their autos, but my H&R pardner pump uses the same chokes as a Remington 870.

Seems like they are invector chokes, like mossberg 500s. browning or H&R singles. Also Baikal. Winchoke too.
