The NcStar MARFQV2 QR Riser Gen2 elevates optics to proper co-witness height while maintaining zero through repeated mounting cycles. This aluminum quick-detach riser transforms standard height optics into absolute co-witness configurations for AR15 and M4 platforms. The locking mechanism ensures consistent return-to-zero performance across hundreds of attachment cycles.
What Makes This Different
The Gen2 design incorporates an improved locking cam lever that provides 40% more clamping force than standard QD mounts. Where basic risers rely on friction alone, this system uses a positive lock engagement that prevents scope creep under heavy recoil. The 6061-T6 aluminum construction weighs just 3.2 ounces while supporting optics up to 2 pounds without flexing.Key Features
