I had reservations about the alternative construction methods of the rimfires for several years.
Worked with several.
All functioned perfectly.
All quite accurate.
I see few reports of breakdowns.
They seem to be holding up (recognizing that ANY company will put out the occasional lemon).
Checked with my gunsmith of 30 years, he doesn't get them in for repairs (and he's one of the best in the state, with a good-sized clientele).
I finally quit waiting for them to prove themselves.
If the alloy-based receiver & cover does the same job at less weight & slightly less cost than carving a frame out of a chunk of steel, then it becomes more of an emotional issue than a performance issue.
The cheaper Henry levers are not as "nice" as a Marlin, but they don't cost as much as a Marlin, either, and they provide an entry level gun for people either on a budget or just getting into the game.
The Golden Boys are a step up & can be quite nice guns.
Henry offers a good range of pricing, with rimfire models that cover entry to fancy, and the guns are the slickest levers on the planet.
They include different sight & barrel options that you don't & won't see with Marlin .22 levers.
Or Winchester.
Buy or not, I'm just saying they seem to be working & that's the thing that counts.
