Just found this out, but wondering what their reasoning was.

Marlin was out of the picture, winchesters and henry's were pricey, lever's were in all time high demand.

There were a lot of complaints when introduced, but after some working-in I didn't hear anything really bad about them.
People who couldn't afford old Win or Marlin's, I recommended them with a grain of salt, but everyone seemed to like them once they worked the action a few times.

Only things I didn't like was the tang safety (but that was any safety on a lever and they pretty much all have them now) and the fact you had to hold in the lever for each shot with the action closed, but new shooters didn't seem to have an issue with that one.

Seemed like a good time to capitalize on the $500~ lever gun range. I doubt the Ruglins will be coming in less than $800

I don't think I ever saw one. So I haven't noticed they went missing

I saw a couple. Held a couple. Negative press might have doomed them. Levers kind of went by the way side when the 464 was introduced which was right after Winchester stopped producing the 94. Budget bolt actions took over the entry level market.

I saw old pre 64 94's at my local shop on the shelf for $350, used but with a lot of life left.
Then corona virus hit, elections, and everything has gone through the roof and stayed there. Levers are probably in the highest demand that they have been in over 20 years because the are still 'safe' when looking at other likely ban targets.

I suspect that the plan to D/C the 464 was in place before all this went down, and the manufacturing capacity went to other higher margin items like shotguns and budget bolt actions.

Unless they surprise us and bring out a marlin-esque lever, which would be cheaper to produce, but given that marlin should be making a come back I think that is less likely.

It is just a shame they couldn't capitalize on the times and get over the stigma the 464 had to sell more of them. I don't think they were bad guns.

I handled a 464 tactical when they first came out, wasnt really impressed with it. Never saw another one after that, havent seen the Mossberg single shot rifle in a long time either

We have a couple of 930s here and there are a couple of 20 gauge 'women & kids' 500s in the family. I just unloaded a Patriot I purchased new last summer. All purchased brand new in the past 10 years. All but two of them required significant tune-ups and/or factory replacement parts to make them usable. I used to like Mossberg, but their execution and QC suck.

I looked at the 464 when it was introduced, but the manual safety and too many end user complaints put me off of it.
