Guys, this is something we have been working on with Mark Housel at L&M Precision Gun Works. Its currently in the prototype phase, but should be ready for prime-time in the not to distant future.



Its a standardized interface system to allow users to get their slide milled once and switch optics as they please. Its also future optic compatible (to an extent), so you won't have to get another slide or get it re-milled for the next generation of micro dots. Simply buy the adapter plate to fit.



We are starting with Glocks & M&Ps using the Aimpoint T-1, Trijicon RMR, and Leupold Deltapoint. Other optics and platforms will eventually be available.



Please let me know if you have any questions.

That looks to be a great design will be interested in seeing how it works out for you. Good luck!

Good catch. All you sight installers take notes.

Personal Opinion: You'll sell a HELL of a lot more units if you eliminate the cost of milling the slide!



Design an optic mounting plate system with an integrated tall rear sight BUIS that mounts in the current rear sight dovetail. Package that with a matched-height front sight. So you have 2 pieces that the average guy with a bench vise can install. No milling required!



But then I'm just practical like that...

I suspect the rear sight sized cross-sectional area of the unit you propose might have some issues holding up to the shear forces generated by the slide cycling against the inertia of the sight and mount.

Build it out of titanium... STILL cheaper than milling the slide in 2 places and tapping the required screw hole...



I like his design, but when you add up the cost of the mount, the milling, AND the micro-optics, you could buy a new AR-15 for the cost of the mod!



There's a LOT of bearing area in the rear sight dovetail of an M&P. You'd increase the bore-axis/sight-axis differential by a bit (which results in hold-over), but I doubt you'd have mechanical stress issues. Dove-tail mounting the system would raise your whole sight-plane another 1/2"??? It's not optimal, but it's not horrible. Put a can on the gun, and you're that high anyway...



I'm still waiting for a good accessory rail optic mount that wraps around the slide allowing a forward mounted optic, that does not cycle with the slide! Yes, you eliminate an easy holster option, but you also eliminate the thrashing your optic gets with slide cycle. You's also be able to pop it on and off like a laser/light.

Although I really like the design, what's the application? Not many guys are going to be switching between different red dot sights on the same weapon



We have an M&P40 slide milled for the J-point/Doctor MRDS, our 1/4 oz. J-point has an integrated rear sight that works well with a factory front sight, and I for one am not interested in swapping it out with a 4 oz. Aimpoint monolith.

My fantasy would be for handgun companies to supply all pistols with milled slides and a plate with a dovetail for a rear sight. As dot sights grow in popularity and are manufactured smaller, tougher and (hopefully) a bit cheaper, I think they'll become much more common. You could then get the dot sight of your choice with the required adapter plate. Or you could choose to leave the factory rear sight on the factory adapter plate. OR you could install a low profile adjustable sight on an extra adapter plate and switch out depending on what game you're shooting.



The potential modularity of a milled slide with an adapter plate makes me salivate.

Guys, thanks for the responses and interest. The whole project started with a request for a T-1 mounting solution. Surprisingly a LOT of end users want this. The other issue is height of the optic. If you have shot a milled

Slide vs dovetail adapter slide, 1/2" does make a difference. We looked at an integrated sight solution but nixed it for a few reasons.



I think the main draw is a standard. So knowing you can try a different optic, or just buy a new adapter plate for optics that may come out in the future.



The prototypes should be cut in the next few weeks and we are working on getting the adapter plates mass produced.



Thanks again for the interest and comments.

I was thinking in a bag filled with other guns...
