RPM Delta 35mm Cantilever Mount (1.50'') No Bubble

The RPM Delta 35mm cantilever mount is a lightweight, precision scope mount built for shooters who refuse to compromise on accuracy or weight savings. Designed and manufactured in the USA, this single-piece cantilever delivers the rigidity needed for long-range and hunting applications while keeping your rifle lean. The 1.50" height positions your optic at a comfortable cheekweld height for most stock configurations, and the integrated recoil lug keeps everything locked in place through repeated firing cycles.

Built from 6061-T6 aluminum with a 303 stainless steel cross bolt and nut, the Delta mount balances durability with minimal mass—the 35mm variant weighs just 5.8 ounces. The design includes an alignment lug that ensures the ring cap and base stay perfectly indexed during installation, eliminating the guesswork and potential for scope ring misalignment that can cause optical shift. This is a no-frills, no-bubble piece of hardware: robust engineering without the extras you don't need.

RPM's reputation for precision manufacturing shows in the details. The Delta series was engineered to improve accuracy while cutting unnecessary weight—exactly what serious hunters and long-range shooters demand. Whether you're mounting a tactical optic on a precision rifle or a hunting scope on a backcountry rig, this cantilever mount delivers the holding power and repeatability you expect from a American-made scope mount.

Frequently Asked Questions

What scope tubes does this mount fit?

The RPM Delta 35mm mount is designed for 35mm diameter scope tubes. If you're running a 30mm or 34mm optic, RPM offers those variants separately in the Delta series.

How much does the 35mm Delta mount weigh?

The RPM Delta 35mm cantilever weighs 5.8 ounces, making it one of the lighter single-piece cantilever mounts available without sacrificing strength or precision.

What is the height of this mount?

The mount places the center of your optic at 1.50" above the rifle's receiver—a height that works well for standard and magnum rifle stocks and positions your scope for a natural, comfortable cheekweld.

What torque specs should I use when installing this mount?

Tighten the cap screws to 18 in/lbs and the cross bolt to 45 in/lbs. The included alignment lug helps ensure the cap and base stay perfectly aligned during tightening, preventing the ring twist and optical shift that can happen with misaligned mounts.
