Deltapoint Pro on M&P CORE

[JetNoiz]

Has anyone successfully mounted, and zeroed, the new Leupold Deltapoint Pro on their M&P CORE? I am considering switching from my RM07 to this optic but have heard it does not fit the CORE.

 

[Rastoff]

I don't know if it will fit. However, you already have the best RMR on the market. What is it about the Deltapoint Pro that is making you want to switch?

EDIT: Check this site:https://www.leupold.com/hunting-shooting/scopes/deltapoint-reflex-sights/deltapoint-pro/ They say they have an adapter plate for the M&P in the works.

I wanted to see if the aspherical window on the Deltapoint Pro made it easier to acquire the red dot. I have COREs in 9mm and 40 so I will still use my RM07, unless the Deltapoint is vastly better.

Leupold is supposedly working on an adapter plate to mount the DP Pro on a Core. I say supposedly because a number of things they have announced over the past couple of years never materialized.

 

[Rastoff]

Ah, well, if you have more than one gun to put this on, I say go for it. Please allow us to humbly learn from your experience.

How hard can it be to make an adapter plate? I'm sure I could do it. Alas, I don't have either a C.O.R.E. or a Deltapoint Pro.

Odd they wouldn't make the new pro fit the same bases as the standard/last years Delta point. Is the footprint that different?

 

[Rastoff]

It's a good question WH, but it doesn't need to be dramatically different to be different enough. This one has different controls and battery access. If any aspect of it needed to be moved even .05", that's enough to require a different base.

From what I've seen, the DP Pro is longer than the DP as well as the registration bumps are in different places. The two screw holes are in the same place. The one instance where I saw a post on how to modify an existing plate was that the back portion of the plate and the registry bumps had to be milled off. I think the removal of the registry bumps would be a problem in regards to holding a zero. I think the best bet would be to wait (and hope) that Leupold makes the conversion plate that they are working on. I also believe you have to remove the rear sight because the DP Pro comes with a flip up backup rear sight. Info is pretty scant since the Pro has just recently become available. Just seems odd that they wouldn't have made it compatible with the Core from the start given the number of Core's that have already been sold.

I have both the Deltapoint Pro and the M&P CORE. It's true and not rumor that due to the placement of the mounting holes in the pro (where it screws into the CORE) the front is about a hair off so it does not fit flush unless you want to mill the CORE. The plate Leupold is working on will allow it to sit flush on top of the CORE.The pro is also taller than other red dots thus you need longer mounting screws and the sights do not cowitness. You will have to buy Leupolds rear sight attachment and most likely swap out the front sight. I can post pictures later if anyone wants to see what I'm talking about

Thanks for the clarification, I was going off discussions on various forums. Pictures would be appreciated (even though I have no plans to buy the Pro, as long as my original DP keeps working).

Sir,

I would be indebted if you could post some pictures of the (mis)fit. I have access to a mill and a machinist that could "tune" the CORE for a perfect fit. There seems to be two schools of thought about co-witnessing the irons with the red dot. I am in experimentation mode to see if the CORE/DPPro combo is better than the VORE/RM07 combo - at least for me. But, I will be happy to post my experiences once I get a DP Pro mounted...

 

[MattMudd]

Sorry it took a couple of days to get these pictures out to ya'll. Depending on the size I might have to put these on a couple of posts. The first few picture shows how the baseplate and optic are supposed to fit on the CORE and how the sites co-witness. I had to file down the S&W #2 plate which was originally made for the Deltapoint 1, to fit the Deltapoint Pro. Once I did this the plate fit and aligned perfectly for the Deltapoint Pro however once I tried to put them in the milled area the Pro was a hair to long in the front. You will have to mill/ lathe the M&P a hair to make it work (might want to wait since Leupold is working on a plate). Another pic shows the Deltapoint Pro sitting flush (no plate) to show it does not co-witness with the OEM sites.

 

[MattMudd]

Part 2 you will also need to file the baseplate to make the Deltapoint pro fit, I used a dremmel with a metal wheel since there is metal and plastic that needs to be filed down. Without the #2 baseplate the screws barely fit but with the plate they do not. These are for both the Leupold Deltapoint Pro screws and the Smith and Wesson screws

 

[MattMudd]

Part 3 this shows the how I made the Pro fit in the S&W OEM baseplate.. looks worse in the pictures.

 

[MattMudd]

Part 4 so here you can see the problems after the fact. My department will not allow me to alter the weapon at all so I can not mill /lathe the upper. Even without a baseplate the Deltapoint Pro is too high and covers the rear sites so no OEM cowitness.

 

[Smithpride]

I'm not going to all that work. Core plus trijicon and be done.
Hope it works for you.

 

[MattMudd]

I agree. I bought the Pro "assuming" it would already work with the C.O.R.E. big mistake. Honestly I was surprised Leupold did not test it on the C.O.R.E. and have a plate / sites already. I purchased the C.O.R.E. so I would not have to buy accessories once I added a Red Dot. I imagine Leupold will charge $40-100 for the plate, and additional for sights and you're tacking on $200 plus to make a system "compatible". The good thing is the Deltapoint Pro makes for a great red dot on a rifle or shotgun. Though now I have to buy the accessories for those. All in all I don't recommend the Pro for the C.O.R.E. unless the solution they have is too awesome to pass up.

 

[Rastoff]

The Trijicon fits perfectly and co-witnesses. It's the highest quality optic. Tell me again what the Delatpoint Pro has that the Trijicon doesn't?

Bought it anyway

I also assumed that the dp-pro would mount on the CORE. Found out the hard way as well. However before I bought the dp-pro I compared it to a vortex venom and Trijicon rmr. The venom and trijicon both have round dots and the dp-pro has a triangle. To me the dp-pro is much brighter and the target acquisition is much quicker. The field of view is much larger, and the aspheric lens has noticeably less distortion than the vortex and the trijicon under the same conditions. I have a gun smith currently working on a custom plate to mount the dp-pro on my M&P Pro CORE 9MML. The one thing we noticed that makes the work around more difficult is, even if you make a custom plate the holes on the dp-pro do not line up with the CORE and fit within the gap the CORE has to mount the flex sight. So my gun smith's solution is to make a plate that allows the dp-pro to sit on top of the slide about 1/16 maybe less forward beyond the gap the core has for mounting flex sights so the dp-pro holes will line up with the CORE holes. Hope this helps a little if only for more information.

Hmmm, my Trijicon has a triangle:

Maybe you just didn't see that model?
