Ruger PC9 Co-Witness Mount

Img Referenced Midwest Industries

The Ruger 9mm PC comes with Picatinny rail on top of the receiver. Any mount would work whether to be QD or thumb screw mounts.

The tip of the front sight post is about 7/8" above the bore, and the top rail is closer to the bore than for a standard flat-top AR15.

We recommend the Midwest Industries Side red dot mount (For Aimpoint Micro footprint ONLY) exclusive with the MI-CRPC9X MLOK rail for the best 1/3 co-witness on the Ruger PC9.

Reticle Size

3 moa vs 6 moa dot sizes comparison

9mm PCC is great for close quarter, therefore a 2 to 6 MOA size reticle are perfect for engaging targets up to 100 yards with a tight group.

Since 9mm isn't a precision round, so having a large MOA dot over the target gives the shooter the coverage area for effective hits.
