Why HoloSun - HoloSun 510C open emitter red dot sight is proven to work very well for real steel use, and it's a great option for airsoft training guns as well.

    What To Look For

    Red Dot VS Reflex Differences

    Most red dot sights fall into the reflex optics category.

    Reflex Sight works the same way as a red dot sight, but they are typically open emitter sights like Trijicon RMR, Holosun 510C where the LED emitter is exposed instead of a fully enclosed body design.

    In outdoor airsoft training environment, open emitter red dot sight can attract debris that can block the emitter screen. It's worse if mud is splashed all over the optic.

    Effective Range

    The effective range for these red dot sight is only as accurate as airsoft bb ballistics. The most effective zeroing range for an airsoft gun is 20 - 30 meters.

    For the most part 6mm 0.25g BBs are much more accurate for airsoft guns shooting around 350 - 500 fps with a much stable flight path.

    Airsoft users are NOT going to zero an airsoft gun the same way as a real gun because the BB's trajectory isn't consistent.

    Dot Size Selection & Astigmatism

    Red Dot Sight MOA Sizes

    The bigger the dot, the easier it is to pick up to superimpose it on the target for fast engagement.

    For airsoft users, a 2 - 6 MOA dot is recommended for all CQB training environment under bright daylight.

    Glass Quality

    Most optics are made up of high quality glass that feature durable coating, optimal light emission angle, eye safety, and parallax-free.

    For airsoft force on force training, we highly recommend to add clear lens protection against BBs.

    Long-Lasting Battery Life

    holosun 510c battery

    50,000 hours of battery life is the industry standard for a red dot sight, and currently most red dot sights can last long with a single CR123A battery.

    A long lasting battery life eliminates the need to replace the battery, and it can stay on in your airsoft range bag.

    Unlimited Eye Relief & Parallax Free

    The biggest benefit of a red dot is unlimited eye relief and parallax free, which allows the shooter focus on the target plane without:

    For CQB airsoft targets, just place the parallax-free reticle on target to get an combat effective hit.

    Faster Target Acquisition Speed

    Whether you're on the move or transitioning through corners. A red dot sight is extremely fast for acquiring sight picture without using traditional iron sights with both eyes open.

    It works the same way as on a real gun, but the bulky safety glass and mask may make it awkward to get behind the optic.

    Drop Proof

    For serious mil-sim airsofter players that may bump their gear in and out of the vehicle or drop their guns while running.

    For the most part, you don't have to worry about the optics getting damaged. These optics even in the $150 range can survive more physical abuse than the airsoft gun itself.

    Recoil Proof?

    Airsoft guns don't simulate hard recoil at all like the real thing even when using gas blowback guns. So there is nothing to worry about here.
