RMRcc vs. 507k - Topic (2024)

Thoughts on the two compact sights?

Side loading battery is the obvious plus for the Holosun.

Other pros/cons of each sight?

RMRcc has a proprietary mounting pattern that fits almost nothing that isn't custom milled. It doesn't fit the P365X/XL, the Glock 43X MOS, the Hellcat, or anything that is cut for the Shield RMSc.

It would be good on custom milled 1911 or other narrow slide pistol.

The 507K fits most RMSc pattern slides, except the Glock 43X MOS needs two of the recoil bosses milled down.

I have an RMRcc that I am not using. I wouldn't mind trying to use it on a riser for a PDW, or on an angle mount on an AR with a scope, but I haven't found any mounts.

I use https://www.trex-arms.com/prod...fle-upgrades/mounts/ for all my RMR & Holosun offset mounts. Very sturdy & work quite well.

Slide in question is custom milled for either footprint. Trying to decide between the two optics so I can order the slide, lol.

The Holosun is also $100 cheaper and does offer reticle options, as another data point I missed.

I'm trying to remain loyal to the Trijicon line but, Holosun keeps knocking it out of the park. The easy battery swap being the winning option. I still haven't bought my own though, just trigger time on friends guns.

I'm confused on the comments about its mounting difficulties. I bought the RMRcc, the trijicon mounting plate and easily put them on my 365XL. My only advice there is to get some quality screws and toss the included ones. They are junk and will twist apart with little torque.

The only argument against the 507K is that it's made in China. The 407K/507K use a relatively common footprint (modification of the footprint on some guns may be required due to different recoil boss dimensions), side load battery, multiple reticle system, red and green options, and an integrated crude rear sight notch that is usable if desired and ignorable if not.

The RMRcc uses a proprietary footprint, higher deck height, and bottom load battery. I believe it is also longer, making retaining iron sights on some subcompact pistols an issue. The higher deck height can be a problem with getting proper height sights for some guns.

I’d hold off for the Holosun EPS Carry.

I do not see any RMRcc mounts here, only RMR. RMRcc and RMR have different patterns.

I’ll spend an extra hundred and stick with Trijicon for my uses.

I am still pissed at Eotech. May get over it someday.

While I appreciate the sentiment, any XPS series holosights are supposed to be good to go now and they seem to have gained some traction back in the LE market.

The EFLX is a different technology(traditional red dot instead of holographic), different application, and about ten years newer than the problem holographic sights.

So trying to pick at this product (which is indeed new and unproven) based on the HWS issues of ten years ago is about like not buying a new F150 because the Pinto was a deathtrap.

Rmrcc has $100 rebate on them now which is very enticing for the rmrCc

I use the Holosun HS507C-X2 ACSS Vulcan (sold by primary arms) on my Staccato XL and Staccato P. I use the Holosun 407k (green dot) on my Staccato C2.

I have one Leupold Delta Point Pro remaining on a Glock 34.

I've sold all of my RMR's.
