McMillan Announces New Tactical Scope Rings


Phoenix, AZ (January 19, 2010) – McMillan is manufacturing 30mm and 34mm tactical scope rings in 1” and 1.2” height. McMillan’s professional tactical scope rings are precision-machined allowing for true repeatability and combat strength. The McMillan tactical scope rings have a ¼ minute of angle (MOA) repeatability when using a 1913 Picatinny rail system, so users can remove and reattach their scope with confidence.


Rings are machined from solid aluminum, steel or titanium and are made as serialized matched set with caps marked to individual bases for orientation. Each set of tactical scope rings is serialized from initial operation to assure both rings are machined from the same barstock, enhancing uniformity. The weight of each ring is 2.9 ounces to 7 ounces depending on the type of metal used. All McMillan tactical scope rings are finished with advanced coatings such as QPQ Black Nitride (melonite), Mil-Std 8625 type III hard coat or PVD coatings.


According to Ryan McMillan, vice president of McMillan, “McMillan’s focus is building a superior product so our customers can focus on their mission.  We hold our rings to the strictest machining tolerances for greater uniformity and shot-to-shot repeatability.”
