PA 3x Mount


Got mine today, along with the 3x Magnifier. Excellent combo. Perfect 1/3 lower co-witness height with the spacer. Solid lock up in both positions. Very similar to the Vortex 3x mount. Smooth plunger, solid lock up, easy to use.

Works great with the PA 3x magnifier and can be mounted to flip either to the left or right for ambi shooting needs. Nice solid lockup with the push button. Great value, will be buying more to pair with additional PA magnifiers.

I can’t say enough about this flip to side magnifier mount. Sturdy, like everything I have seen and used from PA , when you match this mount with a bottom interface magnifier you get the range you need. For up close and personal shooting, just press plunger and flip out of the way. With PAs warranty you can’t go wrong. If you run a red dot or a 1x micro prism don’t let people tell you that you can’t use a magnifier and get great results. And as always I can’t say enough about Primary Arms customer support. If you have a problem, if it can be rectified, they make it happen.

Can we get a 4th view?


Can we get the image of the rail mount knob side? Is it just six sided bolt or does it have a flat? Without it being a quick release do I need a socket to remove or can I use a screwdriver in the end of the mounting bolt

Great mount


I love this mount. Very well built and operates perfectly. However, if you are using this for an Eotech, I would go with the non-lever magnifier mount.

Not a bad product

I ordered the wrong one. I wanted the flip mount without the push button. This mount is not bad though it just depends on uses preference. I used it until the one I wanted arrived in the mail. Had no issues. Just don’t like the button or the bulky mount.
