Laugo Arms Alien Optic Mounting Screws (RMR/SRO) M4x12 Pair - LA-PT-M4
Product Description
The Laugo Arms Optic Mounting Screws for Trijicon RMR/SRO (LA-PT-M4) are official factory OEM replacement fasteners engineered specifically for securing micro red dot sights to the Laugo Arms Alien and Alien Creator optic top rails. Precision-machined to M4 x 12mm thread specifications with modified countersunk heads, these screws ensure proper thread engagement, exact torque transfer, and flush optical interface alignment without interfering with internal top rail mechanics.
Designed to maintain absolute zero under high-speed competition fire, these screws feature high-tensile steel construction that resists shear stress, vibration backing-out, and thread stripping. Purpose-built for Trijicon RMR, Trijicon SRO, and compatible RMR-footprint micro red dots, the LA-PT-M4 set is sold as a pair to replace lost, worn, or rounded factory mounting hardware.
Whether staging a new optic setup on your Alien Creator top rail or keeping vital spare hardware in your match range bag, these factory-spec M4 x 12mm mounting screws deliver precise fitment and uncompromising optical security.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Direct factory fit for securing Trijicon RMR / SRO footprint optics onto Laugo Arms Alien, Alien Creator, and Remus Optic-Ready Top Rails. Note: Thread pitch is metric M4 x 12mm. Sold as a pair (2 screws). Always verify screw length relative to optic body thickness to prevent bottoming out into top rail internal linkages.
- Verify the firearm is completely clear, safe, and unloaded before servicing.
- Place the optic onto the top rail's RMR/SRO recoil studs, ensuring clean contact with the mounting plate.
- Apply a drop of non-permanent medium-strength blue threadlocker (e.g., Loctite 242/243) to the M4 threads and hand-torque evenly in alternating steps to 12–15 in-lbs using a precision torque driver.
