Holosun HS403GL - First Glance

First topic message reminder :

Holosun HS403GL – First Glance

The first thing I noticed was how well the sight was packaged.  (Except for the picture of a standard HS403 on the box)  It gave confidence that the product contained inside was constructed/handled with care.  Lifting out the small User’s Manual and removing the foam cushioning revealed a snugly packed sight, battery, hex wrenches and lens cloth.  Rubber bikini covers were also in place to protect the lenses.  The sight itself was quite small, but had some weight to it.  Construction quality looked excellent, and I couldn’t find any signs of poor craftsmanship.

I understood immediately why shooters are comparing this sight to the Aimpoint T1.  It is very similar in size, weight and appearance.  One big difference however, is the brightness controls.  On the T1, brightness is controlled with a rotary knob which also houses the 3 volt battery.  On the Holosun HS403GL, brightness is controlled with top mounted push buttons labeled (+/-).  I found these very easy to use and unlike other brands, these gave a nice positive click when the button was depressed.

Inserting the battery was a no brainer.  Just unscrew the side mounted battery cover and insert the supplied CR2032 battery positive (+) side up.  It took a few tries to get the cap back on as the fine threads were difficult to align, but once they were the cap was easily snugged up against the rubber O-ring.  After removing the lens covers, I found that the sight had already powered itself up. The HS403GL uses a motion sensor and it was clearly doing its job. (It auto-offs after 8 hours of no use)

Looking through the lens, I found the 2 MOA red dot to be crisp and precise and the brightness range was excellent.  Taking the sight indoors, I was able to adjust the intensity of the dot to properly account for the lack of ambient light. Out in bright sunlight, the unit was able to achieve enough brightness to make the dot stand out against the sky.   I’ve use plenty of red dot sights, and many are either too bright for indoor use or not bright enough when faced with the summer sun.  The Holosun did not have this problem.  Lens quality was also excellent. Like nearly all red dot sights, there was a slight greenish tint when looking through the tube due to the lens coating.  Lens clarity was near perfect and the reverse magnification which can occur in some sights, was very minimal.

Mounting the HS403GL couldn’t have been easier since this unit has a built in rail clamp system.  Just loosen the single pass through bolt with the supplied wrench until the sight can straddle your Weaver or Picatinny rail.  After your certain the sight is sitting flat on top of the rail, tighten the same bolt back up.  That’s it.  Just sight it in and you’re ready to go.  And speaking of sighting it in…this sight uses low profile windage and elevation covers which double as adjustment tools.  There is a small blade on the top of each cap which can be used like a screwdriver.  There are also indicator lines on the inside of the cap and an arrow which lets you know which way to turn the adjuster to move the dot up/down or left/right. This is also very much like the Aimpoint T1 which uses raised dots to insert into the W/E adjustor.  Both are quite handy, easy to use and make adjustments in the field a snap.

If you have a Weaver or Picatinny rail on the top of your weapon (and who doesn’t) you can mount the HS403GL on anything.  I chose to put mine on an M&P 15 (.223) using the supplied riser.  This gave me co-witness with my existing flip up iron sights.  After spending about 15 minutes sighting the dot in using a laser boresighter, I loaded up and took a few test shots.  A few more minor adjustments and I was ready to go.  The first fifty rounds found the sight to be extremely accurate.  There were no signs of movement and even after 100 shots fired…no further adjustment were necessary.  This unit appeared to be rock solid.  As time passes and I have more experience with the Holosun HS403GL, I’ll post updates and let you know how well it continues to function.  For now, I’m going to give this product a 9 out of 10.  It might not have the prestige of the Aimpoint T1…but at ¼ the price…it’s going to give it a run for the money.  You can buy a Holosun HS403GL at www.legendaryoptics.com for just $199.99.  Shipping is always fast and free.

Truglo sells the same sight, or one that looks exactly like it, on Amazon for $117:

I have one on a Nelson for a few months now.  I did have one instance where the scope went into the program auto-off mode (dot blinking) during slow fire, otherwise it's worked well.   


I do wish it had knobs instead of the tall covers for adjustments though.

this is a Holosun 403B..The tubes were made from 30mm ID graphite tubing... I now have added the front cap from a UD 30mm dot so that a UD filter can be added..  they work very well.  we use the 403GL most of the time.. on 45s we have changed out the base to an Aimpoint H1 which seems to work well..  We have this one on a 38 Super with stock bases and no issues..

I actually glued the tubes on with Golf shaft epoxy.. not going anywhere...  If you like a 2 MOA dot these things are great.

Probably 8-1000 on the super and slightly less on the 45.

The Holosuns do have a life time warranty last I looked

What blows my mind is that Aimpoint only has a 2 year warranty for professional/competition use or 10 years for consumer use. You better believe I'm telling them its consumer use if it breaks after 5 years. Almost every big name optics company has gone to no questions asked lifetime warranties. I wonder how long Aimpoint will hold out.

Pretty sure I got it off eBay from a Chinese company  Around $20 for 20" of so. most of the graphite golf shafts and fishing rods are made in China these days..

I'll double check the ID of the tubing today.

the shaft epoxy can be found at places like golf clubs supply houses.. it is a somewhat unique epoxy in that it never gets brittle and has high tensile strength.. it's all that hold golf heads to shafts these days.. a little goes a long way.

To cut the tubing I use a fiber cutoff wheel on my Buffer /polisher.. It's a 6" wheel and is fairly narrow..  Cutting graphite is "different"..  also be careful of splinters when handling a cut shaft or tube... they are more painful than any steel splinter..  I sanded both the inside of the tubing and the sight just a bit with 320 grit paper to give the epoxy a bit of rough surface.. after gluing one tube I cleaned up the inside of excess with a cotton swab... until it hardened the epoxy can be cleaned with alcohol or acetone.. dried over nigh so you end up doing one tube at a time.

here is on of the tubes with a UD 30mm silver cap glued in place. this gives you the option to use their filters.

I received the tubing from Hong Kong and the golf club epoxy from Amazon. A friend set up a jig to hold a Dremel to cut the tubing chucked in his lathe.

The one meter length of tubing should last a while.............

I've put one shade on a Primary Arms sight (made by Holosun), another on an Aimpoint to replace a pressed-on aluminum one that keeps coming off, and will have some on a couple Holosuns on my backup guns shortly.

They look good. Haven't shot them yet, but I believe they will be fine.

Many thanks to jglenn21 for the information.
