The LaRue Tactical SPR / M4 Scope Mount QD 30mm – Flat Dark Earth (FDE) is a precision-machined cantilever scope mount engineered to secure 30mm riflescopes to MIL-STD-1913 Picatinny rails. CNC-machined from 6061-T6 bar-stock aluminium, this mount features a forward cantilever offset of approximately 1.5 inches to provide proper eye relief on flat-top receivers. It incorporates an integral structural backbone linking the vertical split rings to eliminate ring misalignment, supported by threaded steel inserts that prevent ring-screw stripping under heavy recoil.

Key Features

• Dual QD Locking Speed Levers: Proprietary quick-detach locking levers with user-adjustable tension nuts deliver verified return-to-zero repeatability across removals and reinstallations.
• Integrated Cantilever Offset: Pushes the optic forward by approximately 1.5 inches over the receiver and handguard junction, eliminating the need to bridge optics across receiver gaps.
• Rigid Backbone Architecture: One-piece base and ring alignment design eliminates the need for manual ring lapping while maintaining concentricity.
• Recoil-Rated Construction: Built from 6061-T6 aluminium with steel hardware, rated to handle recoil profiles from .223 Rem / 5.56 NATO up to .300 Win Mag.

• Finish: Flat Dark Earth (FDE)
• Mounting Interface: MIL-STD-1913 Picatinny rail with dual Quick Detach levers
• Weight: Approx. 200–210 g (approx. 7.1–7.4 oz)

Who is the LaRue Tactical SPR / M4 Scope Mount QD 30mm - FDE for?

• AR-pattern and modern sporting rifle shooters — Requires a 1.50-inch optical centerline height and a 1.5-inch forward cantilever to achieve natural head positioning and correct eye relief over straight-comb receiver setups using this 30mm cantilever scope mount.
• Precision rifle competitors needing return-to-zero optics — Relies on the dual adjustable quick-detach levers to swap or service optics without losing zero, while maintaining a lightweight footprint of approximately 200–210 g on the rifle chassis.

Less suitable for: Setups requiring clearance over top-mounted laser/illuminators (which require a taller 1.93-inch height mount), optics needing eye relief extended past the 1.5-inch offset threshold (better served by an extended cantilever mount design), or firearms equipped with Weaver rails and proprietary non-Picatinny dovetails without adapters.
