Y TAC RETICLE

The Y-TAC reticle is designed for optimum low-light performance and speed. In appearance it resembles the “ GI ” wings and post front-sight assembly on U.S. Military rifles since before WWII. The aiming post is 0.9 MOA, or 0.9” wide at 100 yards, and covers 0.45” wide at 50 yards. Reticle system is set for the Mil system at 10X setting on the variable scopes. The basis for the reticle is the WWII Post & Crosshair pattern, but differs by featuring a short 1/4 mil x 1 mil tall post, (easily seen in poor light), surrounded by protective “wings” on both sides, just as the rifle. This provides a rapid-acquisition [ Iron-sight ] floating in the center,
with 10 mils of holdover below, to 1000 yards.

The main feature of the wings is that they provide a range-finding gauge by the distance between the outside points and corners, being designed precisely to fit the outside shoulder-width of the B-27 Target : a distance of 21.6” wide, which is 6 mils wide at 100 yards. The wings gauge from 150 yards (outside upper wing points) all the way to 500 yards (between the inside vertical uprights)…[ see diagram ]

For hunting, the reticle also fits the Coyote, broadside (front leg to rearend)

For lowlight situations when seeing the crosshairs is difficult, a bold, or thicker aiming device is needed. During WWII, the Germans used the famous bars with the pointed post reticle: two heavy bars on the sides and a gap in the middle. The post is vertically centered within this gap, in a distance figured for the shoulderwidth between the bar and the post point at 100 meters range.

Further ranging estimation was done by simply fitting two-men shoulderwidth for 200 meters, three shoulders for 300 meters, and so on. With the range determined, the marksman turned a ballistic cam elevation drum to the range indicated…1 – 8 for 100 to 800 meters. The Russians used this same type system also.

Combat experience proved this to be a big improvement in poor-light shooting, but even this needed improvement as the sharp point on the aiming post could be lost or very hard to see on a dark or shadowed target in low light. To correct this problem, the Germans cut off the sharp point, or blunted it deliberately to create a small flat cutting edge ( square flat ) on the tip of the post which stood out much better in bad light. This squared-off point subtended a man’s shoulderwidth at 500 meters range and created an excellent combat sight picture with head-shot accuracy
to 300 meters, and effective hit range of about 800 meters. In contrast, the German square tip covered shoulderwidth at 500 meters on scopes of 3 to 4X , where the flat square aiming post on the Y-Tac reticle covers head-width at about 750 yards at 10X on the fixed and variable scopes. This gives almost three times the precision at approximately 50% more distance.

The Y-Tac reticle, being photo-engraved on the finest German glass, has no wires to break. The wings around the post act as a rapid ranging gauge from 150 to 500 yards, and provide a bold, low light combat sight-picture which aids in centering targets quickly under stress. The upper wing flats help prevent canting the rifle as they ‘ level ‘ with the shoulders of the target.

Like the WWII reticle, the Y-Tac uses a post aiming point and horizontal crosswire,but at 10x magnification instead of 2.5x used in WWII, with a correspondingly huge increase in precision capability due to the four-fold increase in magnification while retaining a small, but highly visible post aiming point for poor light shooting. Windage mil-marks are on each side of the wings and post, with the lower outside vertical edge of the wings providing a 1 mil lead from post center - aiming ahead of the target, with the edge center of mass. {See diagram} The Y-Tac uses the horizontal crosswire as the bold Y-wings center the target rapidly, making heavy bars on the sides of the Y-Tac unnecessary. Overly heavy bars could otherwise obstruct the field of view or in worse case, hide an enemy close by on the flank of your intended target with possible negative consequences.

* Note : I O R’s MP-8 reticle bars are just 1/2 mil thick ( Perfect size )

For Law Enforcement use, the ranging ability / speed of the reticle and low-light capability may be a useful asset to consider. The excellent Y-Tac Reticle-to-Target contrast is uncommon, with I O R’s superior lens coatings and German glass. For close range work, the post covers 0.45” wide at 50 yards (little finger) , and covers 0.9” wide at 100 yards (thumb), as well as bridge of the nose – T box .
For use on a perimeter rifle for Law Enforcement, or a Designated Marksman’s rifle, the task at hand is often in poor light conditions, where this reticle is designed to perform well, when crosshairs fade into the darkness.
With a 100 yard zero, using an M16 A2 with 62 grain bullet, the round will strike the top of the post at 100 yards, and impact 1.1 mil lower at 300 yards or ( 0.1 mil below the post ). Therefore the Y-Tac can immediately neutralize threats within a 300 yard radius of your position, just by using the top or bottom edge of the post. The wings gauge the distance by shoulderwidth while pre-positioning the target (on the wing corners) for upper body hits to 400 yds without further movement of the weapon, measuring 300, 400 and 500 on the lower corners of the wing gauge, and 150 and 200 on the upper wing-gauge outside and inside corners . {See diagram}
