Nightforce Standard Duty 20 MOA Base

Nightforce Standard Duty bases are designed for firm, durable mounting on 1913 Picatinny rails. The base is machined from aluminum and hard anodized for scratch resistance, aligning with Mil-Std 1913 rail specifications. This 20 MOA base provides additional elevation travel to support longer-range shooting while maintaining a streamlined one-piece design for easy installation and reliable tracking.
WOSUWENGE 0 MOA Picatinny Rail Mount

Designed for pre-2003 Savage 110 and related long-action receivers, this 0 MOA base provides a flat baseline for zeroing. The 7-inch length with 16 Picatinny slots offers flexible ring placement. Built from 6061-T6 aluminum, it balances lightweight performance with rugged durability for hunting and mid-range target shooting. Not compatible with short-action calibers or newer receivers.
KPY CZ 457 30 MOA Picatinny Rail Mount

Built for CZ 457 actions, this 30 MOA cant increases elevation range to support longer shots. Crafted from aerospace-grade aluminum and CNC machined for precision fit, it delivers a secure base that maintains alignment and quick, repeatable returns to zero after disassembly.
Monstrum Extended Series 30 MOA Cantilever

Designed for long-range scopes, this 30 MOA cantilever one-piece mount fits 1 inch and 30 mm tubes. It’s engineered to mount on flat-top Picatinny rails with locking bolts that minimize wiggle and hold zero under heavy recoil. The 3-inch spacing between rings accommodates taller objective lenses and larger adjustment housings.
Monstrum Extended Series 30 MOA 30 mm Cantilever

This 30 MOA 30 mm cantilever mount is optimized for long-range optics. It uses a one-piece design, with lightweight construction and rigid mounting to maintain sight alignment across different recoil profiles. Compatible with flat-top Picatinny rails and backed by Monstrum’s mounting system for repeatable zeroing.
Monstrum Hypergrip Cantilever with Quick Release

Hypergrip QD mounts allow tool-free optic swaps while maintaining zero with adjustable tension QD levers. The forward offset supports flexible optic placement, and mounting to flat-top Picatinny rails is secured via the Hypergrip locking mechanism. Designed for quick adaptation in changing field conditions and ranges.
Leupold BackCountry Cross-Slot Base 20-MOA

Leupold’s 20-MOA BackCountry cross-slot base is machined from 7075-T6 aluminum, enabling compatibility with Picatinny and Weaver-style rings. The cross-slot design enhances alignment consistency and is suited for Remington 700 SA layouts, providing reliable elevation travel for longer-range engagements.
Techhunters 30mm Precision Mounts

Techhunters offers 6061-T6 aluminum Picatinny cantilever mounts with a 30 mm diameter and 1.43 inch center height. The design emphasizes precision fit and durable construction, including hardened lugs and full ring lappings to minimize optical distortion and reduce vibration-induced accuracy loss. Includes quick-release options for rapid optic removal.
Buying Guide
- MOA value and elevation needs: 30 MOA bases add elevation travel for long-range shooting; consider 0 MOA when primary elevation is achieved by the optic itself.
- Action compatibility: ensure base fits your receiver (e.g., Remington, Savage long action, CZ 457). Some bases are model-specific for a secure fit.
- Material and finish: aluminum bases with hard anodizing resist scratches and corrosion; lighter alloys improve weight but may trade durability.
- One-piece vs. two-piece: one-piece mounts offer rigidity and quicker setup; two-piece mounts can provide flexibility for ring spacing and eye relief adjustments.
- Locking mechanism and wiggle: look for locking bolts or quick-release systems that minimize movement after mounting and during recoil.
- Rifle platform nuances: flat-top Picatinny rails are common; ensure cross-slot compatibility if using legacy rings.
- Weight considerations: longer, heavier bases may affect overall rifle balance; select based on your primary use (hunting vs. target).
- Accessibility and installation: some bases require specific tools or torque specs; confirm manufacturer recommendations to avoid overtightening or damage.
