Personally, I would not worry about it too much. The newer lever action are just "barely" in-the-"Spirit" and some have really gone past that. …..Just don't post a picture of it here--the lever gun inquisition board will have you crucified.
They are cheapies--but I haven't had one fail yet (including on 45-70, AR's and magnum handguns). The TRS25's I've bought--all but one eventually fell apart under repeated use.Everything is relative, compared to an Aimpoint Micro, those PA red dots are cheapies.
I expect a tube type sight is where I'll end up, but I want something with a low mount, so I'll throw a TRS25 on for testing... then maybe get out my Christmas list and add something better.
