![]() ![]() The head-targets used for this exercise were reduced in scale to simulate aiming at distances beyond 50 yards. > EoTech 551 with the 65 MOA ring/1 MOA dotĪll shooting for this ballistic exercise was conducted from the bench at a distance of 50 yards using my Lothar-Walther barreled AR-15 and match-grade, hand-loaded ammunition. > Aimpoint T1 with an advertised 4 MOA dot I think your use will determine which to get, the real answer is both.įor this ballistic exercise, I did a brief comparison of the level of accuracy that was attainable when aiming with four different “red-dot” sights. I'm not a fan of eotech, wouldn't mind putting more rounds through the vortex uh-1, seemed like a viable option with a short look at it. The MRO lives on a vector or a 22lr ar15 where speed on steel is the goal.Īimpoint t2 may be a good compromise between the two but more monies. Caps would be nice but not totally necessary if it's not going to live an overly rough life, battery life is still plenty good, not a perfect clear picture but nothing like my rmr with it's blurred glass and blueish tint. The MRO is very open when looking through it, its short and belled out to make vision closer to seamless around the body of the unit, adjustment knob on top so the sides can stay slimmer meaning less field of view loss, it's compact and light, plenty of mount options, mine lives in a scalar works mount that I'm fond of. Mine went several feet under water for about a half hour once, I can speak to its water proofness. The PRO is physically large and weighs like 2.5x as much, more of a tube when looking down it but not bad, maybe a tad sharper dot, lens caps are handy, probably has a few more settings, limited on mount options, holding it you can tell she's ready to be run over with a car then picked up with likely very little poi change (not sure it's actually that tough, but it's a tank). The MRO is more of a range, speed, fun type optic. The PRO is hands down the answer for a hard use, duty, apocalypse type optic. I have both, and own/have shot numerous others. You're comparing apples and oranges in my opinion, your intended use will determine what's best for that gun. The solid black dot on the target was the point-of-aim. This simple methodology is illustrated in the two pics shown below. Next, an 8-shot parallax test-group was fired in the following manner:Ģ shots fired with the red-dot positioned in the extreme 12 o’clock position of the sight window.Ģ shots fired with the red-dot positioned in the extreme 3 o’clock position of the sight window.Ģ shots fired with the red-dot positioned in the extreme 6 o’clock position of the sight window.Ģ shots fired with the red-dot positioned in the extreme 9 o’clock position of the sight window.Īdditional 8-shot parallax test-groups were then fired sequentially at 15 yards, 25 yards and 50 yards in the manner described above. Shooting from the bench-rest set-up with the Aimpoint Comp M5 atop the precision AR-15 at the initial distance of 7 yards, an 8-shot control group was fired with the red-dot centered in the sight window. The methodology for this ballistic exercise was as follows. The set-up was very similar to that pictured below. Wind conditions on the range were monitored using a Wind Probe. The ammunition used for this exercise was one of my match-grade hand-loads topped with the Sierra 52 grain MatchKing. This AR-15 has a 20” Lothar Walther barrel with a 223 Wylde chamber and 1:8” twist and it routinely produces 0.75 MOA 10-shot groups at 100 yards (with a high magnification scope). The Aimpoint Comp M5 has a 2 MOA red dot, as does the Trijicon MRO.Īll shooting for this exercise was conducted from my bench-rest set-up using one of my precision AR-15s. In this ballistic exercise we’ll be looking at the amount of parallax error occuring during objective, controlled, live-fire testing at the distances of 7 yards, 15 yards, 25 yards and 50 yards when shooting with an Aimpoint Comp M5 and a Trijicon MRO mounted on a precision AR-15. Inherent parallax error with a red-dot sight is typically greatest at CQB distances (MOA wise) and decreases as the distance to the target increases. Most of us are already aware that this is simply not true at all distances. Some manufacturers of red-dot sights have made claims that their red-dot sights are “parallax free“. ![]()
