It should be noted that the zeroing scheme espoused by Mr. Howe in the above article is not a 100 yard zero, as stated above. It is a “3 inch offset” at 100 yards zero. This means that the bullet impacts 3” higher than the point of aim at the distance of 100 yards. Depending upon specific barrel length and ammunition used, this effectively makes the “3 inch offset” zero a 280 yard zero; which has a point of impact that is more than 4” higher than the point of aim at its maximum ordinate.

While the “3 inch offset” zero obviously works extremely well for the highly skilled and combat experienced Mr. Howe, it may not be the most practical zeroing scheme for the average AR-15 shooter.
