Snowpeak New SPA M60 Coming for those who love tinkering

I see that Krale now lists SPA M60B in stock in .30 cal and .35 cal, and indicates the following specs for velocity and energy (below)

Mighty intriguing for a rifle in this price category, especially if the accuracy is as good as is reported for the already-available smaller bores.

I wouldn't want the "feed bill" for regular use in the larger bores. But from seeing online disassembly videos of the M60B (looks basic and intuitive with a set of hex keys) it'd be mighty interesting if it might (someday) be possible to acquire an extra set of barrel/probe in the larger calibers (hard to know,yet, if regulator or other parts (regulator, hammer spring, other) would vary substantially), to swap for different seasons/ tasks.

Wes in Canada mentioned on another forum that he will be getting some of the .30 and .35 in a future batch.
