The Ronin P-12 is lightweight and powerful red dot sight featuring both Absolute and lower 1/3 Co-Witness removable mounts. The P-12 comes equipped with low profile windage & elevation adjusting turrets. The P-12 utilizes new state-of-the-art LED technology allowing up to 50,000 hours of operation on a single battery (at lowest settings and minimal feature use for the battery life). The motion-sensing red dot automatically turns on with minimally applied pressure and will enable the auto-shutoff feature when left static for long periods.

Absolute Co-Witness Mount: Absolute Co-Witness allows center alignment of your red dot and iron sights when viewed through the objective.

Lower 1/3 Co-Witness Mount: Lower 1/3 Co-Witness allows alignment of your red dot and iron sights in the lower 1/3 portion of the objective.

All Northtac base mounts utilize a T-1 pattern mounting system that includes four mounting screws for the optic, hex key for installation and will securely attach to any Picatinny style surface.  The lightweight mount is constructed of anodized aluminum and engineered to be extremely durable, rugged and easy to install. The Picatinny MIL-STD 1913 mount can be installed on various firearms such as rifles, shotguns, pistols, air rifles, and crossbows.

    Affordable optic combo that you can rely on and a customer service that is on point to get issues resolved. Had a minor issue out of the box, 2 days later replacement at the door step. This red dot and magnifier combo has very good fit and finish for the price point. Red dot is very bright and adjusts well. Can not beat it especially with the customer service.

    Very Good Quality, Chose this over another brand because of the Shake Awake feature and push button brightness feature which returns to last setting when it comes back on vs. Dial which you would have to crank 5 or so times to get to the brightness you wanted. Also the magnifier was smaller than others for a more compact package.

    On first glance, the P-12 RDX Combo appears to be a quality product at a good price. I’ve only shot it once with no problems, so I can’t speak to long term use thus the 4 vs. 5 stars. The package was shipped without the Lower 1/3 witness mount, but Northtac forwarded the mount quickly.

    Optic and magnifier are both high quality. Mounted these on one of my AR builds and I am very pleased with the performance of both. For the price I payed for this set I could not be happier. They did forget to include the lower 1/3 mount initially, but I called and they shipped it right out. Great customer service on top of a great product. Will buy from these guys again.
