Well, they have quit making the .30-30 lever action Mariner, BUT….
I would tell them to hone all the excess ceramic coating out of the action before they ship them.
Those guns had too much coating in the action which caused things to drag a bit. Also, the hammer wasn’t well mated to the sliding surface. Until I honed it, it was grooving the bolt.
Deburr the main spring retainer so you get a more consistent strike action from the spring.
Make the follower metal or use a plastic that won’t swell from heat and solvent.
Put some anti-corrosion oil inside the magazine tube so it does not rust internally during shipping and storage.
Knock the burrs off the lever safety tab, so it doesn’t wear a groove in the lever or your fingers.
Clean up the T-slot in the lever where the bolt lock rides.
Or just do what you did, Mossberg, stick to shotguns and give up level actions, because you can’t/won’t afford to do them right.
Of all my arms, this one took the most work to make it reliable.
