The MMC adjustable sight will fit the factory dovetail on standard height fixed sight models. Suppressor height front sights will not be compatible with the MMC. The sight installs easily with minor flat filing on the bottom of the MMC dovetail. Check with your local gunsmith if you need help with the installation.
- Compatible with standard height factory front sights.
- MMC will not be compatible with suppressor height fronts.
- Blade height at median elevation position is .260”.
- Sight notch is .125” wide x .090” deep.
Adjustment of the sight is quite 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, simply 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.
This sight will fit the factory dovetail cut. 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
