BURRIS Xtreme Signature Tactical Scope Mounting Rings - Pos-Align

In this review the BURRIS Xtreme Signature rings are examined for tactical shooters and precision hunters who need strong, repeatable scope mounting. The bottom line: these rings excel at securing a scope to a Picatinny rail while offering a unique Pos-Align insert system that lets users correct cant and center the optic without marring the scope finish. For anyone who values a lightweight aluminum mount with serious clamping strength and a built-in method to add up to 40 MOA, these rings are worth considering.

Key Features

• Dual steel clamps: Self-centering dual steel clamps with a full cross-through connection ensure proper centering on any Picatinny rail width while adding extra strength to the mount.
• Pos-Align Inserts technology: Inserts provide perfect centering and maximum scope-to-ring contact so the scope is gripped firmly without risking damage to the finish.
• Virtually sight-in capability: The rings let shooters virtually sight in without moving scope adjustments, streamlining zeroing and saving time and ammunition.
• Misalignment correction: The design corrects for off-center receiver holes or slightly off-center bases and rings, eliminating the need for shims or expensive tapered bases.
• Lightweight aluminum construction: Rugged aluminum construction keeps weight down while remaining robust enough for tactical and high-recoil applications.
• Adjustable cant: Pos-Align Inserts allow adjustment of cant from 0 to 40 MOA to add elevation when required for long-range shots.

Who It's For

These rings are aimed at tactical shooters, long-range hunters, and competition shooters who need a secure, adjustable mounting solution that corrects alignment and adds elevation without complex shimming. The design suits rifles with Picatinny rails and many Weaver-style rails where a lightweight but strong mount is preferred.

Shooters who prefer simple one-piece mounts or who need an exact factory-spec aero interface for optics without any adjustment features may want to look elsewhere; also those requiring integrated bubble levels or specialized quick-detach systems will find these rings focused on secure centering and adjustment rather than rapid detach.
