US Optics FXD Bubble Level Rail Mount – Matte Finish

The US Optics FXD Bubble Level Rail Mount is a fixed-position leveling device designed to mount directly to Picatinny or Weaver-style rails. It provides a constant visual reference to ensure your rifle is held perpendicular to the ground, critical for precision shooting at distance where even minor cant can cause significant point-of-impact shifts. The bubble vial is clearly visible in your peripheral vision without breaking your sight picture.

Constructed from durable aluminum with a matte finish to eliminate glare, this rail-mounted level attaches securely without interfering with optic placement or other accessories. It's compatible with any firearm equipped with a MIL-STD-1913 Picatinny rail. Installation requires standard hex tools (not included). Ideal for long-range shooting, competition, and hunting applications where holdover or wind correction demands absolute consistency.
