Burris AR-F4 Mount

• FastFire 4 compatibility: The AR-F4 is built specifically for FastFire 4 sights, giving a secure fit for shooters who want a dedicated mounting solution rather than adapting a general-purpose base.
• Docter/Noblex footprint: With the familiar Docter mounting standard, the mount matches the optic interface used by the FastFire line and helps maintain proper alignment during installation.
• 1.28" sight height: The raised centerline suits AR flattop rifles well, placing the red dot at a practical viewing height for fast target acquisition and a more natural head position.
• Protective wing design: The mount uses sturdy metal wings around the sight area to help shield the optic body and lens from knocks during transport, handling, or field use.
• Picatinny rail fit: Designed for Picatinny-style rails, the AR-F4 gives a straightforward way to add a compact reflex sight to a wide range of rifle platforms that use this common mounting interface.

About the Burris FastFire Mounts Series

Burris FastFire Mounts are purpose-built adapters designed to attach FastFire Series red-dot sights to specific firearms and mounting platforms. Within the Burris mounting lineup, they serve shooters who want the speed of a miniature reflex sight without resorting to improvised mounting solutions. The series sits in Burris's Mounting Systems range and covers a broad spread of applications, including handguns, rifles, and shotguns.

A defining characteristic of the range is its model-specific approach. Burris offers versions for platforms such as the 1911, Glock, Beretta, Sig Sauer P226, Springfield XD, and Ruger, alongside rail-based options for long guns. That makes the series relevant to competition use, defensive carbines, hunting rifles, and general sporting setups where a compact red dot improves speed at short to medium distances. Burris also notes that these mounts are not compatible with FastFire C sights, and that the line is intended for non-OSP firearms rather than optics-cut slides. In practice, the series is about giving the FastFire sight a stable, platform-appropriate interface that preserves the compact handling advantages of a miniature reflex optic.

About the Burris AR-F4 Mount

The Burris AR-F4 Mount is a dedicated red dot mount for shooters running a FastFire 4 on an AR-pattern rifle or any firearm with a compatible Picatinny rail. Rather than using a low-profile pistol-style base, this mount raises the optic to a more practical carbine height, with the center of sight at 1.28". That height helps the shooter maintain a more upright head position and pick up the dot faster during close-range drills, practical shooting, or general-purpose carbine use.

The mount uses the Docter/Noblex footprint, matching the interface used by the FastFire sight family, and it is specifically configured for the FastFire 4 rather than earlier FastFire models. This matters because a dedicated fit reduces compromise in mounting geometry and helps keep the installation simple. Burris also builds the AR-F4 with protective metal wings around the optic area. In practical use, those side structures add a measure of protection against bumps and rough handling, which is especially useful on rifles that are carried in vehicles, moved through barricades, or used in training environments.

Because it is a mount-only solution, the AR-F4 focuses on one job: giving a compact reflex sight a stable, correctly positioned base on a rail-equipped rifle. For shooters who want the speed of a miniature red dot on an AR flattop without excessive bulk, it provides a straightforward and purpose-built setup.

About Burris

Burris was founded in 1971 by Don Burris and is headquartered in Greeley, Colorado, United States. The company is known for building a broad range of sporting optics and mounting products, including hunting and tactical riflescopes, red-dot and reflex sights, binoculars, spotting scopes, rangefinders, thermal optics, rings, and mounts. That breadth is important in a product such as the AR-F4, because Burris develops both the sight and the mounting hardware needed to use it effectively.

Over the years, Burris has introduced several notable products and technologies, including the Ballistic Plex reticle in 2000, the FastFire mini red-dot reflex sight in 2007, and the Eliminator riflescope with integrated laser rangefinding and automatic bullet-drop compensation in 2010. Burris became part of Beretta Holdings in 2002. In the optics market, the brand has a strong reputation for practical field-oriented designs that balance dependable mechanics with straightforward operation.
