Will the LaRue Tactical LT659 fit my standard Aimpoint PRO or CompM2 red dot sight?

No, the LT659 is exclusively engineered for the bottom-mounting footprint of the Aimpoint CompM4 and CompM4-S. Standard 30mm ring-style optics like the Aimpoint PRO, CompM2, or CompM3 require a ring-style mount and are completely incompatible with this direct-attach model.

What is the difference between the three height-to-centerline variants (LT659, LT659-NV, and LT659-HK)?

The standard LT659 provides a 1.725-inch height for standard AR-15 flat-tops to align with back-up iron sights and magnifiers. The LT659-NV provides a 1.535-inch medium height for an absolute co-witness, while the LT659-HK offers a 1.395-inch short profile specifically tailored for raised top rails like the HK416.

Does the LaRue Speed Lever quick-detach mechanism maintain zero after being removed and reattached in the field?

Yes, the patented LaRue Speed Lever system is precision-machined from bar-stock aluminum to provide repeatable return-to-zero capability. You can rapidly detach and remount the optic on a standard MIL-STD-1913 Picatinny rail without losing your zero, even under heavy 7.62x51mm NATO recoil during rugged Australian hunting trips.

Are there any electrical compliance certifications or AC power requirements needed for use in Australia?

No, this is a purely mechanical firearm accessory with no internal electronics, meaning 240V compatibility, AU mains plugs, and SAA or RCM regulatory approvals are completely inapplicable.

Aimpoint CompM4 Mount - LaRue Tactical LT659

The LaRue Tactical LT659 is a quick-detach optic mount engineered specifically for the Aimpoint CompM4 and CompM4-S red dot sights. Constructed from CNC-machined bar-stock aluminium with a matte black anodised finish, the mount attaches directly to the factory screw-interface on the underside of the optic housing. Utilising the patented LaRue Speed Lever mechanism, it clamps securely to any standard MIL-STD-1913 Picatinny rail, providing reliable, repeatable return-to-zero capabilities when detaching and reattaching the optic in the field.

Key Features

Return-to-Zero Speed Lever: Patented locking quick-detach lever system allows rapid removal and installation on MIL-STD-1913 Picatinny rails without losing the optic's zero.
Direct Housing Interface: Bolts directly to the dedicated base footprint of Aimpoint CompM4 and CompM4-S red dot reflex sights.
Multiple Height Configurations: Available in tall (1.725 in), medium (1.535 in), and short (1.395 in) optical centerline heights to support various weapon profiles, back-up iron sights (BUIS), pivot-mounted magnifiers, and inline night-vision devices.
Durable Construction: CNC-machined from bar-stock aluminium with a non-reflective, matte black anodised surface finish capable of withstanding heavy centrefire recoil impulses up to 7.62×51mm NATO / .308 Win.

Who is the LaRue Tactical LT659 QD Mount for?

Tactical and duty rifle shooters — Requires a 1.725 in centerline height to properly align an Aimpoint CompM4 optic over flat-top rail platforms with inline night-vision systems and back-up iron sights using a quick-detach red dot mount.
Sporting shooters using AR-pattern platforms — Utilises the 1.535 in centerline height version of this quick-detach red dot mount to achieve an exact absolute co-witness with standard-height rifle sights.
Hunters using day optics and night-vision accessories — Benefits from the 1.395 in centerline height profile on raised top rails to maintain proper cheek weld and swap optics rapidly via the MIL-STD-1913 Picatinny rail interface.

Less suitable for: Shooters using 30mm tubular red dots (such as the CompM2, CompM3, or PRO) or micro reflex footprints (such as the Micro T-1 or T-2), which lack the CompM4 direct-screw base and require dedicated 30mm ring mounts or micro-footprint mounting bases instead.
