Product Description

The Primary Arms Mini Reflex 12 O'Clock mount is designed to work with 3x and 5x Primary Arms MicroPrism sights, giving you even more versatility with your magnified optic. This top mount is compatible with GLOCK MOS plates, so you can easily find the perfect combination of 5x Prism and red dot sight. The 12 O'Clock reflex mount securely attaches to the optic base and lets you quickly switch from your prism for medium ranges to a red dot for CQB. If you prefer an offset mount, check out the MDOM, which is compatible with standard microdot footprints. Both 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, the Primary Arms 12 O'Clock Mount is the one for you.
