Holosun – HE407K-GR-X2 Reflex Sight Compact, Durable, Combat-Ready Green Dot

Holosun – HE407K-GR-X2 Reflex Sight Compact

• The Holosun HE407K-GR X2 is a purpose-built open reflex green dot sight engineered specifically for subcompact pistols like the Sig Sauer P365X/XL.
• Compact yet rugged, this optic delivers enhanced target acquisition speed, superior battery life, and intuitive controls making it ideal for concealed carry, everyday defense, and fast-paced competition.
• Building on the legacy of previous models, the HE407K-GR X2 introduces Lock Mode, first seen in Holosun’s 2018 LEM series, which prevents accidental adjustments by locking the control buttons. Designed with Holosun’s ultra-efficient Green Super LED, this optic offers a crisp 6 MOA dot and up to 50,000 hours of battery life, so it’s ready when you are day or night.
• The housing is machined from 7075-T6 aluminum for extreme durability and is finished in matte black for reduced glare and corrosion resistance.
• The side-loading battery tray makes battery changes fast and hassle-free no need to remove the optic or re-zero your setup.
• Ideal for direct mounting on slides with the Holosun K footprint, the HE407K-GR X2 is optimized for slim pistols and requires an adapter plate for four-boss interface slides.
