INTRO TO SFP A second focal plane (SFP) scope means the reticle is placed behind the magnification lens. The advantage of a SFP optic is the reticle always remains the same size as you shift through magnification. When shooting with this SFP scope, be aware that the listed reticle subtensions used for estimating range and holdover are only accurate at the highest magnification.

GUERRILLA DOT BDC The Guerilla Dot BDC is versatile across multiple platforms, calibers, and situations. Delivering fast and accurate target acquisitions with the near 1x view, while also presenting various holdovers for mid-range engagements.

Designed for the AR platform utilizing 5.56 NATO trajectory.

Based on the following ballistics parameters: •Lake City/Federal 5.56 NATO •55gr FMJ/CM193 •Ballistic Coefficient: .243 •Muzzle Velocity: 3,101 •Barrel Length: 16” The Guerilla Dot BDC also includes holdovers for 7.62X51/.308 Win. Based on the following ballistics parameters: • Hornady .308 Win 155gr • Ballistic Coefficient: .435 • Muzzle Velocity: 2,865 fps

BFO RETICLE Based on Minute of Angle (MOA) subtensions, the BFO (Bright Fiber Optic) is calibrated using angular measurements that are derived from degrees and minutes. These angular measurements are then used to estimate range and correct bullet drop in riflescopes, with 1 MOA corresponding to 1.05" for every 100 yards, or 29.1mm.

MOA RANGING Ranging with MOA is very easy and effective by simply knowing the size of the target in inches. If you cannot determine the size of the target, use a nearby object.

Target Size (inches) x 95.5 = Range (Yards) Measured MOAs Target Size (cm) x 34.38 = Range (Meters) Measured MOAs

11

RANGING EXAMPLES To range with the BFO reticle, simply use the 5 MOA markings on windage or elevation to size the target.
