The best 1.7-inch 30mm scope mount depends on whether you prioritize a lightweight low-profile design, a forward offset, or a top-mounted red dot. The Reptilia AUS suits buyers seeking a 7075-T6 aluminum mount, while the Monstrum Deadlock adds a two-inch forward offset. HATSEN’s fixed-height model emphasizes a one-piece LPVO design, and its modular mount offers multiple height options and an RMR-footprint plate. Compare tube diameter, rail fit, height, and optic placement before choosing.

Best for: LPVO buyers looking for a fixed 1.70-inch cantilever mount with a one-piece body and a stated objective-clearance specification.

Buying Guide: How To Choose A 1.7-Inch 30mm Scope Mount
Does 1.70-inch height match your setup?
Check how each manufacturer defines height. The products here describe their measurement as bore height, center height, or centerline height. These terms refer to the position of the scope tube relative to the mount base, but confirm the measurement reference in the product listing when comparing mounts.
Is your scope tube 30mm?
A 30mm mount is intended for scopes with a 30mm main tube. Do not choose by objective-lens diameter: the objective is the front lens, while the tube diameter is the dimension the rings clamp around. Verify the scope’s specifications before buying.
Do you need a cantilever or forward offset?
A cantilever or offset design positions the scope forward of the rail attachment point. The Monstrum listing specifies a two-inch offset. A forward position can help with scope placement, but the right fit depends on the optic, eye relief, and available rail space.
Would a top-mounted red dot be useful?
The modular HATSEN mount includes a plate for Mini RMR-footprint reflex sights. Choose it if that secondary optic arrangement is useful and the sight’s footprint matches. The other listed mount features do not specify a top red-dot plate.
Which materials and finish should you compare?
Reptilia and the fixed-height HATSEN mount specify 7075-T6 aluminum; the HATSEN listing also identifies hardcoat anodizing. Monstrum’s supplied features emphasize weight and offset rather than material. Compare only the specifications stated for the exact model you plan to buy.
Frequently Asked Questions
What does 1.70-inch scope-mount height mean?
It describes the stated height from the mount’s base or reference point to the center of the scope tube. Check the manufacturer’s measurement definition because listings may use different terms.
Can a 30mm mount fit a 1-inch scope?
No. The ring diameter should match the scope’s main-tube diameter. A 30mm mount is intended for a 30mm tube, not a 1-inch tube.
What is the benefit of a cantilever mount?
A cantilever mount places the scope forward of its rail attachment area. This provides more flexibility for positioning the optic, but the appropriate placement depends on the scope and setup.
Which option includes a red-dot plate?
The modular HATSEN cantilever mount lists a 12 o’clock plate for Mini RMR-footprint reflex sights. Verify the sight’s footprint before purchasing.
Are the two Reptilia listings different mounts?
The provided features list the same 1.70-inch height, billet 7075-T6 aluminum, and hardcoat anodized finish for both. The available information does not establish a design difference.
