Weaver Tactical Picatinny Riser Rail 20 MOA - Precision Optics Mounting Solution

The Weaver Tactical Picatinny Riser Rail with 20 MOA is a precision optics mounting solution built for AR-15 and M16 flat-top receivers. If you're running a scope on a modern tactical rifle platform, this riser elevates your optic to the optimal height while adding a 20 MOA upward cant—a real advantage for long-range shooting where that extra angle reduces the need to dial your scope turrets excessively. It's the kind of no-fuss upgrade that transforms your rifle into a more capable optics platform without fuss or secondary tools.

Weaver engineered this riser to work seamlessly with standard ring and optic combinations, so whether you're pairing it with a budget-conscious red dot or a high-end scope, the geometry stays consistent. The construction is aircraft-grade 6061-T6 aluminum with Type III hard coat anodizing—the same material aerospace and precision industries trust for durability and repeatable accuracy. That anodize finish handles field abuse, corrosion, and the recoil impulse of centerfire rifles without shifting zero or showing wear.

Installation is straightforward: secure it to your AR's Picatinny rail, mount your rings and optic on top, and you're ready to shoot. The 20 MOA angle is particularly useful for shooters who spend time at distance where that pre-cant saves turret rotation and keeps you in the scope's sweet zone. It's a small detail that seasoned long-range hunters and tactical shooters have relied on for years.

Frequently Asked Questions

Will this riser work on my AR-15 flat-top receiver?

Yes. The Weaver Tactical Picatinny Riser Rail is designed for AR-15 and M16 flat-top Picatinny rails. It mounts directly to your receiver's top rail.

What is the 20 MOA cant, and why would I want it?

The 20 MOA upward angle tilts your optic forward, which is beneficial for long-range shooting. This tilt angle allows you to use more of your scope's elevation adjustment range for distance, reducing the number of turret clicks needed and keeping you in the optic's optimal magnification and reticle zone at extended range.

What optics and rings will work with this riser?

The riser is engineered to provide optimum mounting height for standard optic and ring combinations. As long as your rings are Picatinny-compatible and designed for typical tactical scope heights, they will work on this riser.

How durable is the aluminum construction?

Aircraft-grade 6061-T6 aluminum with Type III hard coat anodizing is built to withstand field use, recoil, and corrosion. The anodize finish protects the aluminum and resists wear in rugged conditions.
