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}
