Questions & Answers
Can someone explain this reticle in detail? What’s the Chevron for specifically.

Most rifles are sighted in for 200 or 250 yards. The AR barrel is about 4 inches below the optic’s centerline, so the bullet crosses the line of site at about 25 yards and again at 250 yards, so the Chevron is for aiming dead on at about 25 yards and beyond. Inside of 20 yards, CQB distance, the bullet will strike low if you use the Chevron. So the upper portion of the reticle allows you to aim dead on at inside of 20 yards and compensate for the bullets path before it crosses the line of sight. In other words the upper reticle makes you aim 4 inches high so the bullet will strike where you want at close range.

Awesome optic by Mike, Verified Owner, November 6, 2023
I took a Trijicon ACOG off my Tavor X95, and replaced it with the Meprolight M21, and I believe this works a little better on several levels. First, it gives the rifle a more correct/ original profile (go IDF !!!). Next, with the 1x power M21, I c...
