Kroll 510C Lower 1/3 Co-Witness Spacer

Description

The 510C lower 1/3 co-witness spacer is an essential mounting component designed to position your Aimpoint 510C red dot sight at the ideal lower third co-witness height. This precision-engineered spacer ensures your optic sits at the correct elevation for consistent aiming reference with backup iron sights, making it an indispensable accessory for tactical rifles, duty weapons, and precision AR-15 builds.

Key Specifications

This 510C spacer is engineered for direct compatibility with Aimpoint 510C red dot sights and standard Picatinny rail systems. The lower 1/3 co-witness design positions your optic mounting surface at precisely the height needed to align with standard iron sight picture, whether using fixed A2 rear sights or folding backup sights. The spacer maintains zero integrity and offers tool-free installation on any standard AR-platform upper receiver rail.

Performance & Ballistics

While the 510C lower 1/3 spacer itself is a non-powered mounting component, it directly impacts your shooting performance by ensuring proper sight alignment. The lower 1/3 co-witness mounting height has become the industry standard for tactical AR platforms, offering the best compromise between red dot sight picture and backup iron sight visibility. This mounting solution eliminates the need for expensive custom upper receivers or replacement rail systems, making it the most cost-effective way to achieve perfect optic height.

Intended Use

The 510C spacer is ideal for shooters building or upgrading AR-15 platforms, M4 carbines, and other tactical rifles. Whether you’re outfitting a home defense rifle, competition platform, or duty weapon, this lower 1/3 co-witness spacer provides the mounting solution professional operators and serious enthusiasts demand. It works flawlessly with modern combat optics setups and complements any red dot and backup iron sight configuration.
