Red Dot or Optic?

Quite often the question as to whether the red dot sight or magnified scope is better for use on an AR/M4 style firearm is best comes up. The answer is really quite simple, in that you should choose the sighting system that best serves your mission requirements. Typically the M4 style of firearm in 5.56Nato is pretty much a 400 meter max range blaster. It can be used effectively at greater distance, but for the most part engaging targets successfully beyond 400 meters is not common when you are involved in any situation where all conditions are not ideal, like when the bullets are coming your way. For most folks, the AR in police and private sector markets is a 150 yard or less weapon. Even military engagements that result in successful placed hits is generally limited to 250 meters or less.

If you can clearly articulate your AR/M4 needs to 150 yards or less, the red dot sight is probably your best choice. Note that most urban use will much less than 150 yards. If your mission is likely to be in terrain or environments of 150 to 400 meters, the optic scope can provide a much wider benefit.

If your evaluation of needs reflects your needs will be in the 150 yards or less, a good quality red dot has much going for it. I recommend a Aimpoint Micro as the way to go. There are many red dot sights on the market, you can pretty much match price with quality. For general range use where the red dot is mostly for pleasure sport shooting, the less expensive versions may have merit. I have a few that fall into this need, and they provide for my needs. For anything that you may be staking your life on, don’t buy cheap; all my serious carbines have Aimpoint Micro T1, H1, or T2 red dots installed.

The fact that you can turn them on and leave then that way for 4 or 5 years is proof of their value, plus they are pretty much bomb proof. Pick a mounting interface that is rugged and reliable. My current favorite is the Scarlarworks Aimpoint Micro mount. I generally mount my Micro over the ejection port far enough forward that my breath will not fog the lens during cold weather.

For a magnified optic, I highly recommend a good 1X4 or 1X5 scope. You must have a low power setting for use at close range, CQB, or low light operations. Some folks demand a true 1 power setting, others do fine with the lowest settings at 1.25 or even 1.5. It depends on your eyes and how well you can focus quickly with both eyes open. Most of the time, your scope will be set on 1 power, or if working in more open terrain, you may click up to 2 or 3 power. One major advantage the magnified optic has over the red dot is in the area of target ID. There are often times that a target beyond 100 yards is not really clear or exposed well enough for clear identity, simply twisting the power ring up to 4 or 5 power will easily allow you to see what you need to know.

The problem with good 1×4 or 1×5 optics is how much to pay. You can spend the equivalent of a good used car, or just a few hundred bucks. I own a 1×4 S&B that has great optics, as well as some rather inexpensive varieties like Primary Arms, Weaver, and Leupold 1.5×4 1″ tube versions. The Trijicon 1×4 T24 is a great optic, and I have a few of these on various carbines. I am not so sure that the most expensive variables are worth the money for my needs. In some cases they can be grossly overpriced. Oftentimes end users choose first focal plane optics, which great for much higher magnification sniper scope use, but terrible for close range carbine applications. At 1 power on a first focal plane scope the reticle will be small and hard to see in low light or dark background environments.

Yes, illuminated reticles can fix this problem, but note that the battery life of most of these models is extremely short compared to a Aimpoint or even the ill famed EOTechs. Remember, the need for a ranging reticle on a 400 yard carbine is a real waste. You can deal with most every ranging issue you have with just hold over out to that distance, even to 400 meters, the trajectory of the 5.56 round is pretty easy to master by adjusting different aiming points. You want an simple easy to use reticle, and you DO NOT need target adjustment knobs on a carbine scope; hey get damaged easily, and move position far to easy with bumps and rubs against gear.

Pick a good rugged mount interface to your carbine. In some cases this may be a quick release throw lever design. Sadly, most of the current offerings are heavy. Everything you add to a 5.56 carbine adds weight. The last thing I want to lug around is a heavy carbine: handy means lightweight.

Consider what you want your carbine to do; what is its mission? Then, select the sighting system that meets your needs.

    Agreed the Aimpoint micro T-1 is an outstanding option in that range. But I’ve never really understood the ACOG hate as an all around choice when you don’t have an option.

    I suppose if you know your engagements are mostly within that shorter range you can load up the T-1. But in some rural areas you really need to be prepared for both short and long engagarments.

    Maybe it’s just me and what I’m familiar with, but I seem to adjust quickly when ranging with the ACOG- whether it’s 50 meters or 400.

    But then again, maybe I’m just getting old and need to get out more.

    Thanks Ken. Always thought provoking.

    • Russell says:

      I think most of the ACOG hates comes from it’s heniously short eye relief tbh. I’ve loved having it on my service gat and it’s never done me wrong, but in my humble opinion there’re just better options out there nowadays.

      • Marcus says:

        Agree completely. The eye relief has always been my one complaint. Especially given some of the more recent entries into the market.

      • TACP Justin says:

        The Elcan isn’t much better. I will say that a MRDS mounted to it or the ACOG provides a good alternative, however it can be problematic aquiring the dot without more than a few ready-ups as it sits a bit too close to the eye. Wish Elcan and Trijicon would look at longer eye-relief and a more distal MRDS bracket.

      ALCON,

      After decades of shooting and a long career in the black boot US Army, I recently took the plunge into the world of ACOGs. Their virtues are numerous….exceptionally clear glass, rugged, lightweight, short, dependable and for me one of the most important virtues….made in the United States of America. Not Chicom crap optics so many folks praise. The one downside to any ACOG being no diopter focus ability. One cannot make any focus change to adjust for individual eyesight. The second downside in most, but not all, ACOGs being the poor eye relief. Although on the TA 33s, TA 47s and TA 44s the eye relief is superb.

      I’m late to the ACOG game. But, better late than never.

  2. Cool Arrow Kicker says:

    Well…. considering that it was selected by a DoD entity over many other variable power optics, I’d roll the Vortex Razor HD Gen II 1-6x24mm with illuminated MRAD reticle mounted in the associated Geissele SOCOM approved mount.

  3. Paul McCain says:

    I appreciate the careful explanation. Good stuff.

  4. Gerard says:

    Great concise explanation. Most civilians put magnified optics on their AR & AKs with thinking rationaly about actually deployment distances. Urban Rifle means using a rifle at Handgun distances.

  5. JKifer says:

    I like my primary 14.5 with TA01Acog/rmr for 0-500ish engagements, however on my cqb upper I have the newish Vortex AR sight, its awesome.. loving that its powered by a AAA…

  6. DAN III says:

    Well written and most pertinent essay by Mr. Hackathorn. For me, very good guidance.

  7. D2 says:

    This is very “training range” oriented opinion essay. One of the biggest advantages of variable magnification optics is target detection and threat determination (a non shooting related advantage). Perimeter teams calling out what’s in peoples hands when they are surrendering based on improved vision of magnified optics at less than a 100 yards, is something I’ve found more valuable in 20 years of work then any body shooting a blazing time on a triple target array for a you tube video. There is a great deal of scrutiny in Military, LE and Private sector about shooting the wrong person for the wrong reason. The more comfortable a shooter is at working at farther distance, especially if he can use it as an intentional tactic based on his equipment; provides a greater increase in safety, reaction time and good decision making on whether to shoot or not. Magnified optics offer this and red dots don’t. Aimpoint makes a great product I just don’t think the decision to run with a red dot should be based solely on some arbitrary engagement distance/price formula.
