📝 Tactical Block Holosun LE420GR with Laser Aiming Module
The tactical block Holosun LE420GR with Laser Aiming Module is a multifunctional device that integrates a green visible laser, an infrared laser pointer, an infrared illuminator, and a 600-lumen white LED flashlight in a single compact housing. It is designed for installation on assault rifles and carbines with a Picatinny/Weaver rail, providing precise target designation, illumination, and operation in both visible and infrared spectrums during day and night missions.
The tactical block Holosun LE420GR with Laser Aiming Module features a titanium housing with a matte finish, ensuring high impact resistance, chemical durability, and full waterproof protection rated at IPX8. The visible and IR lasers are factory-aligned and coaxial, while the IR illuminator supports adjustable focus from 95 to 210 mrad. The unit can be powered either by CR123A batteries or a rechargeable 18650 cell. An additional top mounting platform allows installation of Holosun Micro-series red dot sights, forming a unified aiming and illumination system.
🫡 We — a team of veterans
We are a team of veterans who test tactical blocks in real operational and training environments. The LE420GR is evaluated for night vision compatibility, laser alignment stability under recoil, IR illumination efficiency at various ranges, and ergonomics when used with gloves and under stress. Field use confirms that combining visible laser, IR channels, and a powerful white light significantly improves target acquisition speed and operational flexibility in dynamic combat scenarios.

💬 Comment / comments
Holosun LE420GR is a full-featured “4-in-1” tactical module combining visible and infrared targeting with illumination capabilities. The titanium housing provides superior structural rigidity and maintains zero under heavy recoil. Coaxial alignment of the green and IR lasers allows consistent point of aim when switching between daytime and night vision operation, which is critical for professional and combat applications.
🎯 Suitable for
Military units including assault infantry, special operations, and reconnaissance teams that require a versatile targeting and illumination module for day and night engagements. Night vision operators who rely on IR laser and IR illuminator for covert target designation. Law enforcement and special response units operating in confined spaces and low-light environments where a combination of white light and laser aiming is essential. It is also suitable for professional shooters and instructors building integrated weapon systems with a top-mounted red dot sight on the tactical block platform.
