The LaRue Tactical LT123 is a two-piece quick-detach (QD) mounting system engineered to secure 30 mm rifle scopes to standard MIL-STD-1913 Picatinny rails. Constructed from precision-machined aluminium with a hard-anodised black finish, this mounting set features independent front and rear rings that allow custom ring spacing for various optic tube lengths and bolt-action receiver bridge dimensions. With an optical centerline height of 1.28 inches (~32.5 mm) above the rail, the LT123 provides clearance for optics featuring large objective lenses up to 50 mm or 56 mm over heavy-profile barrels while maintaining reliable return-to-zero capabilities via proprietary cam-locking QD levers.

Key Features

• Independent Two-Piece Design: Allows flexible ring spacing across MIL-STD-1913 Picatinny rails to accommodate varying eye relief requirements and bolt-action receiver bridge separations.
• Quick-Detach Cam Levers: Proprietary QD lever system enables tool-free removal and installation in the field while guaranteeing return to zero when remounted to the same rail slots.
• High Optical Clearance: Provides a 1.28-inch (~32.5 mm) centerline height to clear 50 mm and 56 mm objective lenses over heavy-contour barrels.
• Heavy Recoil Rating: Precision-machined aluminium build designed to withstand the recoil impulse of high-calibre centerfire bolt-action and semi-automatic rifles.

Who is the Larue Tactical LT123 30mm 2-Piece QD Mount for?

• Australian Target Shooters Using Bolt-Action Rifles — Requires independent ring spacing across split MIL-STD-1913 Picatinny receiver bases alongside a 1.28-inch centerline height to clear large 50 mm to 56 mm target optic bells over heavy barrels without losing return-to-zero repeatability when using this 30 mm scope mount.
• Feral Pest Controllers — Needs a rugged 30 mm quick-detach scope ring system that withstands continuous centerfire recoil and allows fast, tool-free optic removal for transport while maintaining exact zero when reattached to standard MIL-STD-1913 rails.

Less suitable for: Optics with 1-inch, 34 mm, 35 mm, or 36 mm main tubes, which require correctly dimensioned dedicated rings. It is also unsuitable for setups utilizing standard inline co-aligned thermal or night vision clip-on devices, as the 1.28-inch optical centerline will not align with standard 1.535-inch centerline clip-on systems; these configurations require a dedicated 1.535-inch inline mount.
