M4/AR15 zero setting. The most simple and useful distance to zero your 5.56mm carbine.
25 yards, 50 yards, 100 yards, what is the best zero setting for your AR15/M4 carbine? I recommend the 50/200 zero setting which allows you to make center-mass hits from the muzzle to about 250 yards. No holdover, on fuss. KISS - the simplest way to prepare your carbine for self-defense.
