The Trijicon Quick Release Mount is a one-piece aluminum base designed to work across Trijicon's most popular combat optics—VCOG, 1x42 Reflex (with ACOG base), and 3.5x, 4x, and 5x ACOG models. If you run a Trijicon optic on a rifle with a Picatinny rail, this quick release mount gives you the speed and reliability that define Trijicon's engineering: mount, unmount, and remount without losing zero or fiddling with adjustment screws.

What sets this apart is the single-lever BLAC (Breech Loading Accessory Coupling) system—Trijicon's patented locking mechanism that clamps your optic to the rail with rock-solid engagement on the first squeeze. No manual tweaks, no guessing whether it's tight enough. Just lever down and you're locked in. The mount holds consistent height across your optics: 1.535" for VCOG and 3x/4x/5x ACOGs, and 1.506" for the 1x42 Reflex, measured from the top of the rail to your optical axis.

Built from aluminum and finished in black, the mount is compact and straightforward—exactly what you want on a working rifle. Whether you're switching between magnified and unmagnified optics for different ranges, transitioning from a home defense build to a precision rifle, or simply maintaining your zero across multiple platforms, a Trijicon quick release mount pays for itself in uptime and confidence. This is the same mount trusted by military and law enforcement users who can't afford equipment failures.

Frequently Asked Questions

What Trijicon optics will this mount work with?

The quick release mount is compatible with VCOG, 1x42 Reflex (models equipped with ACOG base), and 3.5x, 4x, and 5x ACOG variants. If you own one of these Trijicon optics, this mount will lock them in securely on any Picatinny rail.

Will my zero shift if I remove and remount the optic?

The Trijicon BLAC lever system is designed for repeatable, rock-solid engagement. Each time you lock the optic down, the mechanism seats consistently on the rail, which is the foundation for maintaining zero across multiple mount and unmount cycles.

What rail system does this mount require?

This mount is designed for standard Picatinny rails (MIL-STD-1913). Make sure your rifle or upper receiver features a Picatinny top rail for full compatibility.

Is there a height difference between mounting different optics?

Optical axis height is 1.535" for VCOG and all ACOG models (3.5x, 4x, and 5x), and 1.506" for the 1x42 Reflex. The difference is minimal and won't noticeably affect sight picture, but Trijicon maintains this precision so you know exactly what to expect on every optic.
