Any PS-90 owner running an MRO on a Design Machine mount?

[ARCHIVED THREAD] - Any PS-90 owner running an MRO on a Design Machine mount?

Posted: 8/26/2021 9:33:35 PM EDT

I recently picked up an MRO for my PS90.
I ordered and received a Design Machine Mount.

The mount is well made and nicely finished however they didn’t supply the cap screws to attach the MRO to the mount despite what it says on their site.

I do not want to wait to have them ship me 4 cap screws so I’d like to know what size they are so I can source them locally.

I believe that they are a #4 x 5/16” or 3/8”.
Any help would be appreciated.

I'd imagine they'd be happy to tell you over the phone.

Update:
Proper fastener thread for the MRO is #4-48 UNF.
I used 0.375” to mount the optic to the Design Machine mount.

I’m running a design machine mount for the Trijicon MRO. I love it. I would also recommend getting their side rails as well

I regret not getting the side rails.
I’ll probably order them once their cigar cutter front sling mount is back in stock.
