    Great Optic, no buyers remorse., July 23, 2014

    The price is low, the value is HIGH. Fit and finish is… perfect and comparable to the best. I like the auto on feature which was not advertised (UPDATE- is now advertised). The optic will activate automatically when I pick up the rifle. It came with two mounts (low and 1/3 co witness), very nice rubber lens caps, a new Sony battery (the longest life of the watch type batteries) and some tools. This is the low cost alternative everyone had wished for.

    The holographic red dot is indistinguishable in appearance to my Aimpoint 2MOA dot. The glass has a very slight grey green hew when in low light but does seem to **mostly** go away in daylight.

    The only con so far is that the battery compartment was not labeled as to +/- direction and the instructions were a rough translation from Chinese. Fortunately the made in China label is on the bottom and not the side like some of the other HoloSun optics.

    I would highly recommend this Micro Dot Sight to a friend.

    UPDATE 10/8/14
    Battery still good
    500 Rds and holds Zero
    Three other people that have used it commented positively. The price point is amazing.
    Was looking for a con to write but the only thing is the lack of after market mounts, though I have been good with the two mounts it came with. This sight has not been combat proven as far as I know, nor is it advertised as such.
    There is the HoloSun HS403G version that will take AimPoint T1 mounts but is more $$$ plus the cost of the mount.
    ***Be sure to always use LocTite*** as screws do come loose with use.
    Other optics I use frequently are ACOG, AimPoint COMP M4s and M2. I purchased the HoloSun to save money because the cost of an AimPoint T1/H1 is substantial (no regrets). I live in the desert and have not used it in wet conditions yet.

    Update 4/10/15
    Another 1000 rds still going strong. I have since purchased the HS403G but I still like the compact form factor of the HS403A.

    Good value red dot., September 15, 2014

    After looking for a quality optic that doesn’t cost a month’s rent, we finally have ourselves a good option. These guys also make some of Primary Arms optics and everyone knows those are good budjet friendly choices. What Holosun offers directly is a cut above. Thus far I’ve been quite impressed with my Holosun purchases. They’ve held zero on both my AR and AK. Seems to be an extremely accurate red dot as well. I really like the budjet friendly and high value Bushnell TRS-25, but these have become my first choice as a high value red dot. Holosun seems a bit more accurate with it’s 2 moa dot as well. If these prove to be durable over time, I honestly see no reasoning in buying more costly red dot sights. These guys charge what others should. Add to that a limited lifetime warranty and the Aimpoints and such begin looking even less desirable. After my recent experience with their customer service I have no doubt that they will become a fine company to be respected, and will back their products well.

    Possible affordable contender to the Aim-Point series of red-dot sights, December 27, 2014

    This review is from: HOLOSUN HS403A Micro Red Dot Sight (2 MOA) with AR Riser (Sports)
    I’ll simply start this review by stating the obvious, Aim-Point has the micro red-dot market in their pocket because Aim-Point makes the best red-dot sights. Other red-dot manufacturers have come along such as Vortex with their Sparc and earlier models. And Bushnell has offered the TRS-125 which is an awesome little sight at a great price. But the Vortex Sparc does not even come close to the Aim-Point red-dot sights in battery life not to mention the Sparc has a on-off pressure switch which can accidentally turn the Sparc on if the pressure switch is laid against something which depresses the switch. Sounds like little issues unless one depends on a red-dot sight to help them stay alive.

    The Bushnell TRS-125 has a knob with the on position facing the operator and it takes turning the knob to increase or decrease the red-dots brightness level. These are good things to me as is the battery life which is longer then the Sparc but still doesn’t come close to the Aim-Point series of micro red-dot sights or the Aim-Point Comp M4. The Vortex Sparc & the Bushnell TRS-125 have relatively precise, crisp dots like an Aim-Point but both are limited in how much water pressure they can handle as opposed to the Aim-Point. And yes you might say you won’t be swimming out of a nuclear submarines torpedo tube in scuba gear anytime soon but I have seen red-dot sights dropped in water over 15′ in depth and when finally recovered no longer work. Not a good thing if one needs it to help make it through a hunt or other event.

    Now there is the Holosun micro red-dot which touts a 50,000 hour battery life and is supposedly submersible to 100′. The Holosun also has a precise 2 MOA dot which makes for more precise shots. Add to that a limited lifetime warranty & a price tag often around $200 and you now have a clear contender to the Aim-Point’s excellent but expensive series of red-dot sights. That being said I’m only giving the Holosun 4 stars because I don’t prefer pressure switches on my red-dot sights and this Holosun has yet to prove it will actually run for some 5 years ( 3 to 4 years would make me a believer ) or take being submerged in water at some 50′ for a few hours.

    When these events have occurred and the Holosun micro red-dot proves it will do what Holosun touts then I will indeed return to give it 5 stars. But from the outset other then the two pressure switches along the top of this unit I really like this red-dot and upon having fired it mounted to a .308 WIN semi-auto AK variant plus an AR-15 in .223 it has held its zero every time through several hundred rounds of .308 and .223 and stays on in weather under 15 degrees. These are good things and gives me hope that it will have me give it 5 stars about three to four years from now.
