BURRIS P.E.R.P. Full Ring & Base Scope Mount - Solid Cantilever

In this review the Burris P.E.R.P. scope mount is examined as a choice for shooters who need a rock-solid cantilever mount with flexible scope positioning. The bottom line: this mount is for rifle owners who want durable, repeatable alignment and up to 2 in of forward scope positioning to achieve proper eye relief. It is reviewed here from the perspective of fit, build quality, versatility, and real-world usability rather than marketing copy, and the single biggest reason to buy is its one-piece solidity combined with both smooth and Picatinny ring tops for broad compatibility.

Key Features

• One-piece cantilever design: Provides exceptional stiffness and repeatable alignment for mounted optics under recoil and in field use.
• 2 in forward positioning: Allows substantial forward scope placement to achieve comfortable eye relief and full field of view with long-eye-relief scopes.
• Smooth and Picatinny ring tops included: Delivers versatility to accept a wide range of scope tube mounting preferences and accessories.
• Multiple ring sizes and cant options: Available in 1 in, 30 mm, and 34 mm sizes with the 34 mm offering 20 MOA built-in cant for long-range zeroing.
• Durable construction: Built to Burris standards for stability and longevity, giving confidence that mounts, rings, and bases will hold zero round after round.

Who It's For

The Burris P.E.R.P. is ideal for hunters, tactical shooters, and AR platform owners who need a robust cantilever mount that offers forward scope positioning and broad compatibility. Those fitting larger objective or long-eye-relief scopes will benefit from the included smooth and Picatinny tops and the ability to move the scope forward up to 2 in.

Shooters who want the lightest possible mount or an ultra-low-profile option should look elsewhere, as the P.E.R.P. prioritizes solidity and versatility over minimal weight. It is also overkill for compact red dot setups that do not require cantilever positioning.

Pros & Cons

Pros

• Exceptional build quality and a one-piece design that customers describe as "built like a tank" for long-term stability.
• Includes both smooth and Picatinny ring tops, making it compatible with many scope types and mounting preferences.
• Allows up to 2 in of forward scope placement for optimal eye relief and ergonomic shooting.
• 34 mm option includes 20 MOA cant for shooters dialing elevation at distance.

Cons

• Heavier and bulkier than minimalist mounts, which may not suit those seeking the lightest setup.
• Quick-detach models are limited to certain sizes, so QD functionality is not universal across all ring diameters.
