Overview

This compact bubble level is designed to help shooters maintain level alignment on a Picatinny rail setup, making it a practical accessory for precision-oriented rifle use. CNC machined from 6061 aluminum and anodized in matte black, it keeps a low profile while adding only 0.3 oz with mounting hardware. It is compatible with the American Rifle Company M-Brace Mount and is included with that mount, so it is only needed as an additional level. Installation calls for a 3.4 Nm (30 in-lbs) torque spec on the bubble level screw.

Considerations & Trade-offs

  • Included with the M-BRACE mount, so this is mainly a replacement or spare if you need an additional level.
  • Designed for Picatinny (MIL-STD-1913) rail use and compatibility with the American Rifle Company M-Brace Mount, so it is not a universal bubble level.
  • The listed torque spec is specific to the bubble level screw: 3.4 Nm (30 in-lbs), so installation should follow that value closely.
  • At 0.3 oz with mounting hardware, it is very light, but it is still an added component on the rifle setup.
