Holosun 510C Spacer FDE
Spacer for a Holosun 510c. Holosun HS510C / HE510c-GR Spacer to raise your red dot.
The Holosun 510C Spacer FDE is a precision-machined accessory designed to raise the height of the Holosun 510C reflex sight to achieve a lower 1/3 co-witness with backup iron sights. Constructed from durable 6061-T6 aluminum, the spacer adds strength without significant weight, ensuring it can withstand recoil and consistent field use. Its Flat Dark Earth (FDE) finish is designed to match FDE optics and firearm builds, creating a cohesive, tactical appearance.
When installed between the optic and mount, the spacer increases the optic height to approximately 1.63 inches above the rail, allowing shooters to maintain a more comfortable and efficient sight picture while keeping iron sights visible in the lower portion of the window. Easy to install and purpose-built for compatibility with the Holosun 510C Spacer series, the spacer is a practical upgrade for shooters looking to fine-tune their optic setup for improved alignment and versatility
