K-31 and St. Marie Swiss Products

[Navy joe]

Anyone have the St. Marie diopter sights for the K-31? I see these advertised in Graf's and want them badly, but $330 sights on a $130 gun give me pause. How do you like them? Are they worth it? i'm not interested in anything like the Mojo sights or that replace the rear sight scope mount. I want ridiculous accuracy. I have 2 K-31s, I need one more. The plans call for one stock, one with diopters hopefully and one with my ZF-4 Zeiss scope as soon as I make a good reciever mount for it.

St Maire makes both a bolt-on and a smithing required receiver scope mount for the K-31. I'm pretty sure Brownell's carries at least the bolt-on.
