Budget prepping is a difficult thing to do. After all, there is a difference between budget and cheap, inexpensive and cheap. Cheap by definition does not mean something is necessarily bad or of poor quality, however, with some things cheap is bad. Red dot technology has progressed light years beyond the first bulky Aimpoint, EOTech, and Trijicon.

Obviously, Aimpoint as a company has maintained a seriously good reputation and continued to progress with the times, as has Eotech and Trijicon, however, their pricing reflects no shifts for markets unable to afford to spend $600 – $2500 on a simple 1-4 power red dot styled optic.

My search for a less expensive optic commenced several years ago. I worked my way through Bushnell T series which functioned fine but were hit and miss at best. Eventually, I settled on the Bushnell AR scope series and decided to simply move on from the red dot phase.

After all, a solid scope with excellent glass and comparable abilities to other more expensive brands will work in most cases.

This didn’t mean I had no need for a red dot, after all, a solid red dot with a solid pair of backup irons is an amazing thing to have. Quick on target and easy to use, good red dots mean the difference between hits and misses in many arenas, especially combat-related training and combat itself.

Over the past year, I decided to do some research and look around again for a solid red dot under $500. I found several brand names, Vortex, AIM sports, and even Bushnell had new offerings on the market. However, I was drawn to a relatively new company, Holosun©, this optic had serious potential.

After dropping $170 on the HS403B found on Amazon, I received the well-wrapped package and mounting hardware. Two sets, a low riser, and high riser were included. The high riser fit my carbine exactly as needed. Co-witnessed with my irons I took it out to the range and started testing.

holosun-red-dot-siteAfter around 100 rounds I set the rifle to the side as there were other reviews that needed fulfilling and it held zero very well, so what more needed testing. As I leaned it against the carbine rack it smacked the crossbar on the way by and snap, the red dot came off. I leaned over and realized that the screw holding it too the gun had snapped off at the head.

I finished my testing for the rest of the products and called Holosun on the way home.

They assured me that they both knew about the problem and apologized for the inconvenience this had caused, I asked if this was going to be an ongoing issue or if it was a simple flaw in this particular part of the design.

The person I spoke with grabbed another individual who explained that the model I had received was the last in a first gen run and the new gen had the much stronger hardware.

Upon arrival 3 days after the call, I installed the part and decided to test it too its breaking point. After all, nothing to lose at this point as the people I had spoken with assured me they would replace the entire unit free of charge if it happened again.

I dropped tested it on dirt, grass, and concrete from approximately 5 feet. I also decided to “accidentally” smack the red dot housing into a few items during my next test run. Needless to say, it held firm and I have not had a breakage or issue since.

Though I doubt it will take a bullet to the casing as say an Aimpoint will, at 50,000 hours of battery life and with a VERY clear dot picture and glass as well as solid easy on when you pick the gun up, well I think this is my new best friend in the red dot world.

They have different variations, shotgun patterning dots, circle over a dot, plain jane red dot and all of the varieties can be had with a nifty solar-powered recharger put on the top if you want.

The company offers a limited lifetime warranty to the original owner, and their customer service is very expedient and quick to respond, a truly rare commodity in today’s age of somewhat lackadaisical service. They are located in the USA, Walnut California, to be exact.

They offer a 50,000-hour battery life, a variety of aiming products from lasers too red dots. In this case, my interest lying completely in their cost-effective, efficient and extremely solid red dots. The HS507A is compatible with the standard RMR mount and the other red dots have a variety of mountings available with some specifically designed for Aks and others for Ars.

Some options have a quick release mount and others a kill flash and other essential needs for red dots. The best part is their red dots run between $165 and $350 dollars and you can order from Amazon.

Now obviously I have not been able to test the veracity of the 50,000-hour battery life, however, the unit I have has been on and working clearly for well over 6 months without a hiccup. I have no doubt that the longevity is easily better than Bushnell’s offerings and Vortex. The price point allows budget preppers and shooters to have (as the company motto says) “A military-grade optic at under military prices” now personally, I have not tested it in combat yet. However, it has performed well through many tests it is NOT designed for. I do not recommend you treat your optics badly on purpose, that is my pleasure to do for you! Having family and friends still in the military this is the question I ask myself, “would I recommend this to them?”


It works very well, it will be ready for them when they need it, and will function with general abuse and function well. This being said, I am not the desk personnel from the Pentagon and it isn’t my job to accept money to pass along new products to our soldiers.

This being said, what are the pros and cons listed out?


  1. 50,000-hour battery life with an optional solar panel for charging and auto adjustment in all light conditions.
  2. Multiple reticle styles and mount styles available.
  3. Crisp clear dot, brightness easily adjustable or set for auto adjust.
  4. Movement activated the red dot when you pick up your firearm, the red dot comes on!
  5. Built for shotguns, rifles of many calibers and even handguns.
  6. Limited lifetime warranty.


  1. They are a relatively newer company, so not as much time to evaluate and test as other more established companies.
  2. They have had some issues with mounts, however, this is being addressed and is easily fixed, upgraded with a call to their customer service.

Overall, this is a product I definitely recommend and run on my carbines now. MD Creekmore also has one and here is what he says, “I bought this sight a couple of weeks ago and mounted it on my Colt M4 and so far I’ve been very impressed and agree with everything Jesse has said here in his review.

I have an Aimpoint and an EOTech on two other AR’s and the Holosun HS503GU (the model that I have) is just as good as either one of those for half the cost. ”

Free the mind and the body will follow…
