Remington R1


Adjustment procedure

Adjustment of the sight is simple. For windage, the set screw on the left side of the base is loosened with the included .050” hex key, and as previously mentioned, repositioned with a punch (punch should have blunt flat face and contact only the dovetail area). For elevation, use the same .050” hex key (or anything small and pointed – toothpicks work well) to depress the detent plunger on the right side of the base and twist the sight blade counterclockwise to raise the point of impact, clockwise to lower. Release detent to lock blade at the proper position.


Please do not use a sight pusher, and always wear eye protection.

The slide dovetail cut is approximately .115” deep x 70⁰ x .326” wide (see sight dovetail pix to verify correct application). The factory fixed rear sight is to be driven from the dovetail (usually left to right) with the proper punch. Don’t forget to use eye protection. The MMC sight is then fit to the slide by flat filing the ribs on the bottom of the dovetail until a tight interference fit is achieved. The left side set screw provides additional security.

Sight notch is .125” wide x .090” deep

Remington R1

The MMC sight for the R1 will fit what Remington called their “proprietary” dovetail. It is not compatible with the GI 1911 Mil-Spec dovetail (see 1911 page). The MMC is compatible with the factory front sight. Fitting of the sight is normally quite simple, and requires only mild flat filing of the MMC dovetail bottom. No modification to the slide is required. If you have any trepidation about installation, please consult your local gunsmith.

Please see the pictures on the 1911 page as they are representative of the R1 sight.

  • Sight notch is .125” wide x .090” deep.
  • Blade height at median elevation position is .295”.
