Warne 513M Maxima 30mm Matte Black Steel Rifle Scope Ring Set for Weaver/Picatinny Rails

The Warne 513M Maxima 30mm scope rings are a solid choice for hunters and shooters who want proven, no-nonsense optics mounting. These horizontal fixed rings fit standard 30mm scope tubes and work with both Weaver and Picatinny rail systems, making them adaptable to most modern rifle platforms. Built from sintered steel and finished in matte black, they're engineered to hold zero shot after shot without the fuss of adjustable systems.

Warne designed and manufactures the Maxima line in-house at their Oregon facility, and it shows in the build quality. Each ring uses four Torx T-15 cap screws—two per clamp—to lock your scope down with confidence. The permanent recoil keys are squared off for positive engagement between the ring and base, a detail that matters when you're counting on consistency. The STANAG 4694 interface standard enhances rigidity and supports Warne's return to zero guarantee, so if you ever need to remount or service your optic, it should settle back into the same point of aim.

Installation is straightforward: the four-screw cap design and integrated clamp system make setup faster than some competing rings. If you're building a hunting rifle, running a precision bolt gun, or setting up a tactical platform, the Maxima 513M delivers the holding strength and repeatability that serious shooters expect. Warne's reputation for domestic manufacturing and attention to detail is reflected in every detail of these rings.

Frequently Asked Questions

Will the Warne 513M Maxima rings work on my Picatinny rail?

Yes. The 513M rings are designed to fit both Weaver and Picatinny style bases, so they'll secure to either system without adapters.

What size scope tube do these rings fit?

The 513M Maxima rings are built for 30mm scope tubes.

How tight should I make the cap screws?

The rings use Torx T-15 cap screws. While no specific torque spec is provided in the available data, follow any torque recommendations included with your rings or consult Warne's documentation to avoid over-tightening and damaging the scope tube.

Do these rings come with any kind of warranty?

Warne backs the Maxima 513M with a return to zero guarantee, meaning your scope should return to the same point of aim if the rings are remounted on the same base.
