Relevant to the conversation ...
Today I took four ARs to the range with the following optics:
ACOG TA47 2x Green Cross
Aimpoint T-2
Aimpoint CompM4
Aimpoint CompM4S
Based upon what I paid, that was around $2,700 in optics plus the four LaRue mounts (only mount I'll use).
The crystal clear glass on the ACOG still makes me smile (bought my first ACOG in 1994 .... ) and the crisp dot on the AP's (coupled with insane battery life) always help me shoot nice groups.
Today I was confirming 50 / 200 zeros (zero at 50 on paper, and then ring steel at 200 ... POI is very similar on a 50/200 BZ). With old Wolf steel case 55 grain I was shooting 1" groups with the RDS, and hitting an 8" plate 100% of the time (rapid fire) at 200 yards.
