DPP Titanium Mount/Adapter Plate Compatible with RMR Cut Slide Without Thread Post and Holosun 407K/507K/EPS Carry/EPS/RomeoZero ——RM-H07K

Purchased a Holosun 507K from PSA 3 weeks ago to mount on a PSA Dagger. Nothing on PSA’s web site suggested incompatibility. When I realized the issue I immediately contacted PSA for guidance. ZERO help. Didn’t even mention adapter plates were available. Found this adapter here on my own. Read the helpful information and order one. Fits perfectly. No issues. Just ordered another one to mount another 507K to a second Dagger.

Seen a lot of reviews saying that this doesn't fir the dagger RMR slides. Mine fit perfectly on my dagger slide. Not too thick, durable, and easy to install. My Riton mprd x3 fit perfectly, no movement. Perfect function, overall great value for the money. For those saying that it didn't fit the dagger may have the wrong footprint.

Bought this plate for Gen 5 Glock 19. I had the 19 ported and cut for optics. I preferred the profile of the Holoson 507k to the 507c so I grabbed this plate, fits perfect and only added about 2mm of height to the optic

Super happy with my DPP RMR plate. Uses it to replace the other supposedly higher end plate & remount my Holosun EPS to my G19. The DPP is robust & strong yet thin, and it being thin was a game changer for me. Didn’t have to change my irons plus it’s keeps the whole green dot closer the bore. Wasn’t aure what to expect because haven’t had a DPP before & haven’t heard a ton about them. So wasn’t sure what to expect but figured I’d try it since the “high end” plate just wasn’t right. Was pleasantly surprised how nice it was & flat out blown away by the fit & function. Plus extremely affordable, a wildly outstanding value for the money. DPP has become my “go to” for pistol optic mounting plates. I’m not using anything but DPP going forward.

I received the item overnight and it was the correct plate. When I opened the packaging all of the screws were loose from the packaging in the box. The plate had noticeable damage and I discovered a screw had obviously been cut with a cutting wheel to be extracted damaging the plate in the process. I paid full price to be sent damaged junk. Buyer beware!

First, this plate is perfectly machined... The Holosun EPS Carry almost snaps into place with a perfect fit. Outside footprint of the plate perfectly matches Trijicon RMR.A negative is that the plate is quite thick: .08in does not sound like much, but it is 2mm.... On the other hand, the plate seems very sturdy.I have a Sig P229 Legion with optics ready slide, factory-cut for RMR and DPP/Romeo1Pro. There are no lugs on the top of the slide, and the cutout is much bigger than the EPS Carry I wanted to install, so I wanted a plate to fill up the gap and keep the Carry from being possibly affected by recoil.This plate seemed to be the perfect solution, because I could screw the plate onto the slide with the RMR screw holes, and then screw the EPS Carry into the recoil posts of the plate (while also filling up the gap). Unfortunately Sig made the cutout in the slide slightly longer than necessary, so there is still a small gap... At this point I can either use no plate and bolt the Carry directly to the slide, or use the thin plate Holosun included basically as a gasket, or use this thicker plate to fill up most (but not all) of the gap.So if you have a true RMR sized cutout on your slide with correct RMR screwholes, this plate will probably be perfect. If you have an optics-cut Sig slide.... maybe it will still have a gap (but it is not the fault of the plate manufacturer).-----------Update 10/18/23------------I finally decided to install this plate on my P229, and I realized the screws to mount the plate to the slide are not correct for this pistol. M3 screws are included, but I need 6-40. So if you try to use this on a P229 with factory RMR cut be aware you might need different screws. I emailed DPP Titanium to see if they can send the screws I need.

Fits a PSA dagger rmr cut perfectly!

I originally got this for my Staccato that has a rmr cut slide and it didn't have the posts on it either so I thought this would work but the mounting holes don't line up to the slide. I do however have a Glock and that did line up with the holes perfectly. I liked that you got the assortment of screws with loctite preapplied to the fasteners. The titanium material is a bonus too.
