3 1-6x24mm Combat Rifle Scope (CRS) The 1-6x24 CRS, with its proprietary GPC M4-62 (Patent Nos and B2) front focal plane reticle, was designed to cover the full spectrum of combat, from CQB distances to the maximum effective range of modern assault/battle rifles in day/low light tactical environments. The CRS features a dualpurpose reticle. The #1 priority of the CRS is speed on target at CQB distances. This is accomplished by using the horseshoe portion of the reticle on 1 power with two eyes open. In this mode, the CRS will perform like a red dot gun sight. For long-range engagements or accuracy at any distance, increasing magnification and using the aiming dots maximizes precision. The CRS also is compatible with night vision systems, such as the PVS-22, to allow for effective use in low light environments. Very Important When mounting the CRS, do not over tighten the scope rings. Zeroing 1. Adjust scope to 6x. 2. Focus use rear ocular focus ring. 3. Rough 25 yards. The dot in the center of the 300-yard ranging circle (second dot at bottom of horseshoe) should be on the point of aim point of impact. 4. Move target to 100 yards. 5. Fine-tune zero at 100 yards. The first aiming dot in the center of the horseshoe should be on the point of aim point of impact at 100 yards. BDC Reticle Once zeroed, this bullet drop compensating (BDC) reticle is designed to allow for rapid ranging and hitting of head-size targets out to at least 300 yards and chest-size targets out to at least 600 yards. The GPC M4-62 reticle is calibrated for the M4 Rifle (14.5 barrel) using M855 (62gr) ammo. Bullet Drop for M855 Ammo Target (yards) Bullet drop (inches) If a combination (rifle-ammo) other than the M4 with M855 (62gr) ammo is used, aiming points may need to be modified. Also, factors like temperature, humidity, and elevation will affect the point of impact. The extra non-caliber-specific aiming dots on the reticle are designed to assist in dealing with variables.

4 How to Use the Reticle The Horseshoe: For CQB to 200-yard speed shooting, set the scope on low power. The horseshoe will be the aiming point. The reticle is located on the front focal plane; so, the horseshoe will get smaller as the magnification is decreased. At low power, the horseshoe will appear as a big dot (see photo below).

5 How to Use the Reticle (cont.) The long-range precision portion of the reticle will get very small and not be usable at low magnification. As the distance to the target increases, the target will appear smaller and the horseshoe will resemble a circle on the target. At CQB to 200 yards, the horseshoe reticle acts as a big dot or circle-type aiming point to increase speed on target. The horseshoe is 4 MOA thick and 18 MOA wide (shoulder-width at 100 yards). See photo below. CQB/Snap Shooting The #1 priority of this scope/reticle is speed and accuracy during CQB engagements. To maximize CQB speed and accuracy, set the scope to 1x and sight with both eyes open. Turn on the illumination and adjust to the required brightness for low light environments. On low magnification, the horseshoe (HS) reticle works like a red dot gun sight. The HS reticle is very fast for snapshots, on moving targets, and out to 200 yards on chest-size targets.

6 Illumination Very Important The most important thing to remember about the scope s illumination system is that it can be seen from the front under low light conditions. Experiment with this and adjust tactics accordingly. The illumination is not bright enough to be seen in bright sunlight. To compensate for this at close range, increase the magnification to make the HS appear larger, thereby making it easier to see/faster to use. The CRS uses CR2032 lithium batteries. The illumination turret has 11 levels of brightness. There is an Off position between each illumination setting. There are two spare battery storage compartments in the windage and elevation turret caps. Ranging The Window: The hollow center of the horseshoe is called the window. The horseshoe s window is 10 MOA (size of head at 100 yards). With proper zero, the bullet will hit on or very near the center of the horseshoe from 75 to 250 yards. At CQB distances, the bullet will impact below the 100-yard aiming dot (at CQB distance, be aware of the required holdover). The Mil Dots: The six mil dots to the left and the right of the horseshoe serve as anti-canting guides and also, may be used for ranging. Mil dots start at 4 mils from the center of the horseshoe. How to Use the 10-inch Ranging Circles: The window is used for fast ranging on a man-size target at 100, 200, and 300 yards. It is 10 MOA. This equals 10 inches at 100 yards (head-size).

7 Ranging at 200 yards 20 inches at 200 yards (approximately shoulder width). Half the window equals 10 inches at 200 yards (head size). See photo below. 30 inches at 300 yards (approximately half of a man s body length). Ranging Circles: As described above, the window of the horseshoe is to be used as a ranging circle on a man s head at 100 yards. Half of the window will range a man s head at 200 yards.

8 Ranging at 300 and 400 yards The first ranging circle in the center of the open end of the horseshoe will range a man s head at 300 yards. See below. The ranging circles below the horseshoe to the left and right of the aiming dot labeled No. 4 range a man s head at 400 yards. (See photo below.)

9 Ranging at 500 yards The fifth dot is the aiming point at 500 yards. (For engaging targets beyond 500 yards, see page 12.) As the magnification of the scope is increased, the aiming dots will come into clear view. The aiming dots extend downward from the center of the window. (See photo on next page). The first dot is 1 MOA; it is the aiming point for precision shooting from 0 to 250 yards. The second through seventh aiming dots are 0.5 MOA. The Aiming Dots The second aiming dot inside the 300-yard ranging circle is 0.5 MOA. It is the aiming point at 300 yards. The third dot is the aiming point at 400 yards. The fourth, sixth, and seventh dots are non-caliber-specific aiming dots. The fifth dot is the aiming point at 500 yards. (For engaging targets beyond 500 yards, see page 11.)

10 Horizontal Lead Lines Starting at 400 yards are horizontal lead lines and gaps to allow adjusting the aiming point for a moving target or windy conditions. The horizontal lead lines and gaps between the horizontal lead lines allow for leading a target in 10-inch increments at the given distance (approximately either half frontal body-width or full bodywidth viewed sideways). The horizontal lines are 10 inches long at the given distance, and the space (gap) between the horizontal lines is 10 inches at the given distance. Once the distance to the target has been determined using the ranging circles, follow the horizontal lead lines to the center aiming dot. This will be the aiming point for that distance (see photo below). This photo shows ranging on a man s shoulders at 500 yards and aiming at his chest.

11 Engaging Targets Beyond 500 Yards The ranging circles for 600, 700, and 800 yards have been moved to the center line of the reticle. These ranging circles maintain the 10 inside diameter at the prescribed distance. Since it is not realistic to expect headshots at these distances, the most practical way to engage targets is to range on the target s head and then use the ranging circles as the aiming point, center mass on the chest (if visible). Alternatively, range on a man s shoulders at these distances by using the distance from the far edge of the ranging circle to the start of the horizontal lead line. This will equal 20 at the prescribed distance. The 0.5 MOA aiming dots between these ranging circles are non-caliber-specific aiming points. See below.

12 In Summary Advantages of the Norden Performance Combat Rifle Scope with the GPC M4-62 Reticle Most experienced shooters will agree the fastest reticles for CQB to mid-range shooting situations are circle or dot type reticles. At low magnification, the 4 MOA thick horseshoe of the M4-62 reticle provides the speed of a big dot for CQB and of a circle at mid-range distances. Increasing the magnification provides a fast, simple ranging system with precision aiming points out to at least 500 yards on a chest-size target. The illuminated reticle provides illumination for various shooting environments. The CRS will enhance the capabilities and lethality of our war fighters. We believe the CRS will prove to be a force multiplier and increase the survivability of our war fighters. Norden Performance Tel: (424) info@nordenperformance.com
