NcSTAR MARFQV2 QR Riser Gen2 AR-15/M4 0.75" QD Mount

The NcSTAR MARFQV2 QR Riser Gen2 is a locking quick-detach optic riser purpose-built for the AR-15 and M4 platform. Constructed from lightweight black aluminum, this one-piece riser clamps onto a standard Picatinny rail and lifts the mounted optic platform by 0.75", bringing red dots and low-profile optics up to a more comfortable cheek-weld height.

Measuring 5.30" long, the Gen2 design adds an integrated locking QD throw lever so the riser clamps down solidly on the host rail and stays put under recoil. The top surface provides a clean, full-length Picatinny slot pattern for securing red dots, holographic sights, and similar optics.

Designed for rifles, the MARFQV2 installs and removes by hand in seconds thanks to the quick-detach lever, making it easy to swap optics between firearms or remove the riser for transport. Whether running a low-profile red dot on a flat-top AR or chasing a more natural head position behind magnified optics, this aluminum riser delivers a solid, repeatable mounting solution.
