Designed by former Special Operations vet Paul Howe, the new CSAT aperture’s point of aim has a point of impact from 7 yards (using the notch) to 100 yards (using the small aperture at the base of the notch).

At close range, the sight takes the thinking and calculation out of the equation and allows the shooter to engage targets with ease.

100_yard.gifZeroing Procedure

At 7 yards, fire a round group at the base of a black pasty with the sights aligned similar to that of a shooting a pistol.

Adjust the sights so that the rounds impact where your front sight is holding on the base of the pasty.

Once zeroed at 7 yards, move back to 100 and fire 3 rounds at your target using the 6 o’clock or center hold sight alignment using the PEEP sight. Adjust your sights accordingly to make sure your rounds hit where you want them to.

Once zeroed, move back to 7 yards and confirm your close in zero using the front sight and rear notch. You should have a point of aim, point of impact zero.

To see how far you can use your notch and still make a hit, move back to 10 yards, 15 yards, etc. and notice the offset that begins to take place. Use the peep hole when you feel you are too far away for the notch to make a surgical shot. This will be up to the individual shooter to make this determination.
