Holosun HS510C 1/3 Co-Witness Lower Spacer

Holosun HS510C Lower Spacer for 1/3 Co-Witness

This spacer module is designed specifically for the Holosun HS510C red dot sight, allowing you to mount your optic at the lower 1/3 co-witness height.

What This Means

Co-witness mounting positions your red dot sight so that your backup iron sights align in the lower third of your sight picture. This gives you:

• A backup aiming system if your optic fails
• The ability to use iron sights without removing your red dot
• Faster target acquisition with both sighting systems available

Key Features

• Precise Height Adjustment: Positions the HS510C at the correct 1/3 co-witness plane
• Durable Construction: Built to withstand field use and recoil
• Easy Installation: Drops into place on your Holosun HS510C mounting system
• Compatibility: Works with standard Picatinny rail systems

The Practical Advantage

Whether you're running a carbine, rifle, or tactical shotgun, the 1/3 co-witness height is the gold standard for modern sporting rifles. This spacer ensures your Holosun HS510C sits at that proven height, giving you the redundancy and flexibility serious shooters demand.
