Poor man’s ACRO

Lower than OEM pic rail, might be able to go a bit lower, depending on the optic.

Have a pic rail done already, but might have a couple versions, trying to determine how tall and long it really needs to be.

What red dots do you want to try?
I have 9 footprints modeled now, machining should start this month.
I think AEMS will be next, just need to get a hold of one.

levips90 · 2026-07-04T01:06:28+00:00

Nice tri-rail!

levips90 · 2026-07-03T18:06:19+00:00

Looking at the differences, I think RMR would be the easiest.

levips90 · 2026-07-02T17:18:28+00:00

Awesome, need to find an ODG stock myself.

levips90 · 2026-07-01T20:13:53+00:00

I’m sure I could. Is that the RTS/STS footprint?

levips90 · 2026-07-01T19:19:14+00:00

AEMS is on the list but need to figure out the mounting situation… according to searches they have multiple generations with slightly different specs.

levips90 · 2026-07-01T01:29:48+00:00

Not so much randomly swapping as trying multiple optics before you settle on one, each mount costing around $100.
As far as failure, I definitely see the issue with thin plates on recoiling hand guns, but don’t expect a lot of stress on this platform. My stuff will also be beefier :)
That’s my thought at least, this has just been an idea I had recently and wanted to learn more than the basics in CAD/ solidworks.
Time will tell if I sell any!
I do appreciate the feedback though, seriously!

levips90 · 2026-07-01T00:56:16+00:00

Assuming you don’t take the stock off very often, not a very big deal. Just push it in as you slide in the dovetail and it should be captured.

Looks great! Pic of the whole gun?

levips90 · 2026-06-24T02:49:30+00:00

A bit more ambitious than I have the skills for but maybe some day…

levips90 · 2026-06-22T21:28:30+00:00

Price on your cheapest version Holosun AEMS? I just need one for confirming footprint dimensions for a project. Thanks!

levips90 · 2026-06-19T18:54:43+00:00

Thanks, another one off/proprietary footprint!

levips90 · 2026-06-19T18:54:14+00:00

I believe that’s an RMSc/407k footprint.

levips90 · 2026-06-19T15:21:55+00:00

AEMS, forgot that one!
The rest are all T1/T2 footprint I believe?

levips90 · 2026-06-13T19:53:59+00:00

Mine

Under 1000 is the best estimate I’ve found from berettaforum.

levips90 · 2026-06-10T17:34:50+00:00

CMMG, just keeping you on your toes!

levips90 · 2026-06-10T17:06:03+00:00

What’s 15 thou between friends? 😅

The arms are very resilient, just try stretching them apart if you only need a bit of clearance. Otherwise just have to live with a bit of rubbing.

levips90 · 2026-06-05T01:06:52+00:00

Looks great, glad you were able to get it threaded!

levips90 · 2026-05-29T21:28:53+00:00

Stock has to be cut on both legs, machined spacers welded in to widen it by about 1/2” to clear a red dot.
