Holosun 507k

For the 48/43x mos you do as posted above:

Or buy the chpws plate

Yes and no. It’s a similar footprint to the Shield RMSC, however slides milled for the RMSC must have the rear posts removed and the front posts shorted by .015 for the 507K to mount correctly.

Bumping this thread up because I just bought a G48 MOS and the SIG Romeo Zero. I was more interested in the 507k but the dealer didn't have one in but still I wanted MRDS to try out.

Hearing that the 507k fits the same area as the RZ is great. I had been reading conflicting reports on if it would fit the G48 MOS(I guess no one is playing with one yet *shrug*).

I feel the RZ is a mixed bag and I have a feeling a 507k is in my near future.

Thank you for that. I kept seeing back and forth talk it was confusing me. I couldn't find any videos that discussed the actual mounting method either (until today, I finally found one on the 507k and the mounting plate you suggested on a 53X MOS).
