I know it's used, so I expect some wear.
You said it had 1 magazine which is ok. That's what it comes with.
How about the 2 interchangeable gas pistons, allowing you to shoot 2-3/4” and 3” and 3 choke tubes with wrench. All that comes with it when new?
I looked through the online manual.
It warns against shooting the gun without a choke tube in place, resulting in screwed up barrel threads.
Reason I'm asking is, I'm interested in this firearm.
