Tripod Mount for Sig Kilo3K

[rtr]

I recently purchased this rangefinder, https://www.sigsauer.com/kilo3k-6x22mm.html and the folks at MK Machine say none of the ones they make will fit it. Sig says all of their LRFs are different dimensions but that their $100 mount will work. Wondering if there is a cheaper solution out there? See pics with measurements for reference.
