The Primary Arms Mini Reflex 12 O'Clock mount is designed to be used with 3x and 5x Primary Arms MicroPrism sights allowing you to get even more versatility out of your magnified optic. This top mount is compatible with GLOCK MOS plates meaning you can easily find the perfect combination of 5x Prism and red dot sight. The 12 O'Clock reflex mount features a design that securely attaches to the optic base and allows you to quickly switch from your prism for medium ranges to a red dot for CQB. If you prefer an offset mount, check out the MDOM that is compatible with standard microdot footprints. Both of these mounts are made from 6061 aluminum and feature a black hardcoat anodized finish for long lasting durability. If you prefer a more heads up shooting position when transitioning from magnified optic to red dot sight, then the Primary Arms 12 O'Clock Mount is the one for you.

Won't hold zero

The material in this product is just to flimsy. Outstanding idea but it's going to have to be made with a higher level material.

Note: It was good to speak to you on this and get your perspective on this mount. Please let us know if there is anything else we may help you.

Great mount!

Lightweight, very sturdy, and works as expected. Easy to install and very low-profile. The price is also very attractive.

Doesn’t fit as advertised

I like Primary arms and have bought many great products from them. But this product was advertised to fit with the Slx 3x micro magnifier and it does not. Very disappointed.
