For my latest compact AR build I wanted a compact optic and had been looking at Aimpoint, but the Pro is larger than I wanted and the T1 was just too freaking expensive. I put hands on the ACOG minis too, but couldn't justify the expense. I had recently being hearing buzz on the interwebz about Holosun Optics. Starting with erwos's thread here on the HS403C. After looking at the different models I bought the HS403A.
Specs from their site (no I don't think english is their first langauge):
Here it is on the rifle:
It is very low profile and hardly obstructs field of view:
Here is the dot in focus, it is surprisingly crisp and the glass is clear for the price point:
The optic is very solid feeling and comes with a low mount and a lower 1/3 AR mount. The largest problem with it is the fact you need to remove the optic to replace the battery and the mount does not ensure a return to zero. Though with a 50,000 hour life and the 8 hour shutoff feature, the battery should last 10+ years. The auto-shutoff/motion activation works wonderfully. If the rifle is laying on the floor and you pick it up, it will not turn on. But anything more will activate it (actively shouldering it, seating a mag, charging the firearm, two fingered 'tap' of the magwell, etc).
I have had it to the range multiple times and it functions perfectly with positive adjustment clicks and holding zero.
As I am currently living in a house without kids I am keeping the rifle with me at all times as an ongoing test. It follows me from floor to floor and I toss it in the corner or on the couch or onto the safe as I go about my life. After almost two months the sight is still going strong.
As a sub $200 red dot sight, I think this is hard to beat. At this point I would highly recommend it to anyone, but will update this review as needed.

MECHANICAL DATA
Housing Material Aluminum
Housing Finish PEO/MAO housing finish: Plasma electrolytic oxidation (PEO), also known as microarc oxidation (MAO), is an electrochemical surface treatment process for generating oxide coatings on metals. It is similar to anodizing, but it employs higher potentials, so that discharges[1] occur and the resulting plasma modifies the structure of the oxide layer. This process can be used to grow thick (tens or hundreds of micrometers), largely crystalline, oxide coatings on metals such as aluminium, magnesium and titanium. Because they can present high hardness[2] and a continuous barrier, these coatings can offer protection against wear, corrosion or heat as well as electrical insulation.
Housing Color Black
