NcStar MPR45 45 Degree Offset Picatinny Rail Mount Black

The NcStar MPR45 45 Degree Offset Rail Mount transforms standard Picatinny rails into versatile mounting platforms for backup iron sights, red dots, and tactical accessories. This precision-machined mount positions optics at the optimal 45-degree angle for rapid target transitions without interfering with primary optics.

What Makes This Different

Unlike fixed rail sections that limit mounting options, the MPR45 creates dedicated space for secondary sighting systems at the proven 45-degree cant angle. The offset design allows shooters to maintain primary optic zero while adding backup sights or close-range optics. CNC-machined construction ensures consistent return to zero after repeated installations, outperforming cast alternatives that can shift under recoil.

Key Features

• Precision 45-degree offset angle for optimal sight picture and target acquisition
• CNC-machined 6061-T6 aluminum construction with Type III hard anodized finish
• Compatible with standard Picatinny/Weaver rail systems (MIL-STD-1913)
• Low-profile design measures 2.5 inches long with minimal bulk addition
• Dual cross-bolt clamping system with steel hardware for secure attachment
• Accommodates most backup iron sights, micro red dots, and laser devices
• Ambidextrous design works for both left and right-handed shooters

Field testing demonstrates the MPR45 maintains zero through temperature extremes and heavy recoil cycles. The 45-degree angle provides natural sight alignment for close-quarters engagements while keeping backup systems out of the primary sight line. Competition shooters appreciate the quick transition capability for multi-target scenarios, while tactical users benefit from redundant sighting options during extended operations.
