  2. New Vortex Micro, Smaller Magnifier

    FN PS90 Accessories & Mods
    Vortex recently released a new magnifier much smaller in size than their original version, which we use for our 3x Optic Flipper. Vortex has ironically named this new magnifier the "Micro". The new micro has an overall length of just 2.9" vs the 4.3" of the original magnifier. The field of view...
  3. MRO Low Mounted with ARD - Design Machine

    FN PS90 Accessories & Mods
    A customer recently sent us their ARD to try to make compatible with one of our MRO mounts. At first we could not find a way to do it. However once we realized we could separate the ARD from the flip cap cover, we found a way. Unfortunately you can't use the flip cover on the ARD, but you can...

  7. Design Machine FX3 for people with Astigmatism

    FN PS90 Accessories & Mods
    So recently a friend of ours we had review our FX3 3X optic flipper mentioned he had astigmatism which was making it slightly difficult for him to operate his red dot, magnified or un-magnified. He suggested we make a mount for the Primary Arms ACSS Cyclops which is what we've done! Not only can...

  10. Trijicon SRO Specialized Reflex Optic on PS90?

    FN PS90 Accessories & Mods
    Does anyone have one, or any experience? I'm curious of how it stands up to the RMR. They have the same mounting system so they're both compatible with my mount. Interested since I assume Trijicon came out with the SRO to compete with Aimpoints new Acro. Seem's convenient due to the fact you...

  12. Design Machine Custom Leupold Prismatic Low Mount

    FN PS90 Accessories & Mods
    A favor was asked of us by a client to make a custom mount for their Leupold Prismatic. Curious what you boy's think, and if anyone has interest? Some prefer cross-hairs versus red dots and we were happy to make it happen. We at Design Machine are wondering if this is a product we should add to...

  14. Installed an MRO

    FN PS90
    Well, a 15 minute project turned into a hour and a half project. I purchased a Desing Machine low mount for the MRO and installed it pretty easily. However, removing the top rail that came on my rifle was a bear. The front screw came out fairly easily. However the rear one stripped as soon as I...
  15. Trijicon MRO on a PS90 with a Design Machine Mount.

    FN PS90 Accessories & Mods
    I mounted the Trijicon MRO on a Design Machine mount two weeks ago and after a couple of range trips, I couldn't be happier with the combination. It gives a cheek weld very similar to an AR with a lower 1/3 co-witness mount. It's precision is more than adequate, the field of view is great, and...
