The P.E.P.R. (Proper Eye Position Rail) mount is Burris's Picatinny scope mount designed to secure the RT-6 scope to a standard Picatinny rail while providing a co-mounted offset position for the FastFire E red dot. The FastFire E mounts to the P.E.P.R.'s integrated offset section using the FastFire E's Aimpoint ACRO footprint, positioning it alongside the main scope body. This offset configuration is common in 3-Gun and tactical competition setups where a shooter can quickly index their head position to the red dot for close-range stages rather than using the magnified scope. The P.E.P.R. mount is a self-contained solution — no additional mounting hardware is required beyond what is included in the kit.

The Ballistic AR reticle is Burris's competition-oriented design for AR-platform rifles, featuring a primary aiming point and bullet drop compensation (BDC) holdover marks below center calibrated for common AR cartridge trajectories — typically .223 Remington/5.56 NATO loads at standard velocities. The holdover marks allow shooters to engage targets at increasing distances by shifting to the appropriate hold without manually dialing elevation corrections between stages. Because the RT-6 is a second focal plane (SFP) scope, the holdover spacing is calibrated at maximum magnification (6x). For the most accurate hold distances, confirm your specific load's trajectory against the reticle's marked distances and zero at the distance recommended by Burris for your cartridge and load.

The FastFire E's always-on design means the red dot emitter remains continuously active rather than relying on a motion sensor, manual activation, or auto-off timer. This eliminates any delay between drawing or shouldering the rifle and having an active reticle — the dot is always lit and ready. Burris rates the CR2032 battery for up to 60,000 hours of operation, which at a median brightness setting translates to years of always-on use before a battery change is needed. For context, 60,000 hours is approximately 6.8 years of continuous operation. In practice, most shooters will change the battery on a scheduled basis (annually or seasonally) rather than running it to depletion. The CR2032 is widely available and inexpensive.

The Aimpoint ACRO footprint is a mounting standard originally developed for the Aimpoint ACRO enclosed red dot sight and has since been widely adopted across the industry as a compact, secure mounting interface for enclosed emitter optics on pistols, shotguns, and carbines. Because the FastFire E uses this footprint, it is compatible with any slide, chassis, or mount that accepts ACRO-pattern optics — beyond the P.E.P.R. mount included in this kit. If you want to move the FastFire E to a pistol slide with an ACRO cut, a shotgun with an ACRO adapter, or an aftermarket offset mount, the footprint will accommodate standard ACRO-compatible hardware.

Yes — the RT-6 Tactical Kit was specifically designed with new and developing 3-Gun competitors in mind. The value proposition is straightforward: instead of separately sourcing a competition-grade LPVO, a backup red dot, and a compatible mount (and verifying that all three work together), this kit delivers a proven, pre-matched package at a bundled price. The RT-6's forgiving eye-box, true 1x, and Ballistic AR reticle address the core requirements of 3-Gun rifle stages. The FastFire E provides a fast-acquisition close-range option. The P.E.P.R. mount positions both optics for immediate use out of the box. For shooters building their first competitive rifle setup, this kit removes a significant amount of the research and compatibility work that comes with building an optics system from individual components.
