The Weaver 99673 Flat Top Riser Rail provides a solid mounting platform for optics and accessories on AR-15 and M4 carbines. This zero MOA cant rail maintains proper sight alignment while elevating mounted equipment to the optimal height for consistent cheek weld and target acquisition.
What Makes This Different
Unlike basic riser blocks that can introduce alignment issues, the Weaver 99673 maintains precise 0 MOA cant specification throughout its length. The mil-spec Picatinny rail spacing ensures compatibility with standard rings and mounts. Hard anodized aluminum construction resists wear from repeated mounting and dismounting while maintaining zero under recoil stress.
Key Features
- 0 MOA cant specification maintains perfect sight alignment
- Mil-spec 1913 Picatinny rail with standard slot spacing
- Hard anodized aluminum construction for corrosion resistance
- Precision machined mounting surfaces eliminate play and movement
- Compatible with AR-15, M4, and other flat-top receivers
- Matte black finish reduces glare and reflection
- Standard cross-bolt mounting system for secure attachment
Field testing demonstrates the rail maintains zero through extended firing sessions and environmental exposure. The elevated position works particularly well for shooters using stocks with higher comb lines or when wearing protective equipment that affects head position. Law enforcement and competitive shooters benefit from the consistent sight picture this rail height provides.
