Thread: Patternmaster, cure for cancer?

I bought my Mossberg 590 second-hand. I'd just handed over the cash when the guy remembered he still had the factory manual and sling. He scurried off to get them, and when he returned he also had two choke tubes in his sweaty little hand. So I'm looking at these tubes, then I'm looking at this barrel which clearly isn't threaded for anything. So I ask him "What are those for?" He proudly proclaims "These are chokes, you put them into the gun to change the size of the pellets!" I assume he is talking about the shot pattern rather than the pellets themselves, but that doesn't answer the main question. "So where do they go?" He looks at me like I'm a little slow before pointing at the magazine tube cap and saying "You unscrew that and they go in there, that's how they change the pellets". I wait for a buhdumtish or similar but nothing comes. I take the manual, sling and magical choke tubes and hurry to the ute, hoping to never cross paths with this man again.

So yes greghud, choke tubes are in possession of dark powers we do not fully understand, and those salespeople do truly believe what they are telling you.
