See All Open Sight Mk2 Tritium Night Sight

U.S.A.-(Ammoland.com)- I have quite a few black rifles. Most of them already have optics installed on them. I did have one AR that was missing an optic. I started looking around at the different options that were available to me to outfit the AR.

I was thinking about another Aimpoint or an EOTech optic, but in the end, I decided I wanted to try something new. Looking around the market, I found an optic that was like nothing I have ever seen on a gun. That is because by using the strict definition of an optical sight the one I settled on isn't an optical sight at all.

The sight I found was the See All Open Sight Mk2 Tritium Night Sight by Oversight Shooting Technology, LLC. This sight is more like a sight that you would find on a bow than a sight you would find on a gun. The use of a bow sight technology on a firearm fascinated me. I wanted to see if it would translate between the two distinct platforms.

Oversight Shooting Technology was kind enough to offer me one of their gun sights to test out on my AR. I just had to decide whether to use a crosshair reticle or a delta point reticle. I ended up going with the delta point reticle since Oversight Shooting Technology based the original design of the See All Open Sight Mk2 on a bow sight, and I thought I might as well use a bow-like reticle.

Oversight Shooting Technology includes a hex wrench with all their See All Open Sights for mounting and adjusting their sight. The See All Open Sight Mk2 attaches easily to any Picatinny or Weaver rail system which is perfect for flat top ARs.

The one thing I had to do is use a riser to be able to use the See All Open Sight Mk2 on my gun comfortably. I tried to use the sight without a riser, but it was too difficult to use the sight on my firearm at the default mounting height without the riser. Once I added the riser, I was able to acquire targets with the sight quickly.

Oversight Shooting Technology uses 6160 aluminum for the body of the See All Open Sight Mk2. This aluminum is the same material that most manufacturers use to construct the bodies of their optics and a lot of AR manufactures use for their receivers. It is a strong material and was an excellent choice for the sight by Oversight Shooting Technology.

The internals of the See All Open Sight Mk2 is made by Oversight Shooting Technology out of a scratch-resistant polycarbonate. The polycarbonate is robust and can take a real beating. The material is also resistant to temperature warping which is a nice touch.

The See All Open Sight Mk2 uses an Edge Glow polycarbonate for daytime shooting. I cannot stress enough how easy it was to acquire targets utilizing this sight. The Edge Glow technology puts this sight on the same level of ease of use as a reflex sight for me.

The See All Open Sight Mk2 doesn't require batteries for night time shooting. Oversight Shooting Technology decided to use a tritium inlay to illuminate the sight for low light or no light shooting. The sight works well in the dark. The reticle was highly visible at night. The only drawback is that since it runs on tritium, it is impossible to adjust the brightness of the sight.

I installed the See All Open Sight Mk2 on my Radical Firearms .458 SOCOM AR pistol equipped with an SB Tactical Mini Brace. This gun kicks like a 20-gauge shotgun. I figured if the sight would hold zero on this gun that it would be able to keep zero on almost any firearm.

After running through 100 rounds of Freedom Munitions Big Grain ammo, the See All Open Sight Mk2 still held zero. I was impressed by the accuracy of the sight. It was dead on even after a full day of shooting. It gets a big thumb up in the accuracy category.

Another advantage of the Oversight Shooting Technology See All Open Sight Mk2 is that the sight doesn't have any issues with parallax. No matter the angle of shooting or the position of my eye I was always able to get on target using the sight. Due to the design of the sight, I figured this would be the case, and I was happy that I was right.

Oversight Shooting Technology manufactures The See All Open Sight Mk2 in the United States. I love that fact. As I have said in the past, I am willing to pay a little more for an American made product as long as the quality is good. They also have a lifetime warranty on all their sights as well as a 30-day money back guarantee.

Another advantage of the See All Open Sight Mk2 is that it is legal to use on black powder hunts. A lot of states ban the use of optical sights on black powder rifles that the operator uses for hunting. Since the See All Open Sight Mk2 isn't technically an optical sight, it can be used on these hunts legally.

The fact that these sights are not technically optical sights also makes See All Open Sights NSSF Competition Compliant. This use of the sight should be a massive advantage to the competitor.

Overall the Oversight Shooting Technology See All Open Sight Mk2 Tritium Night Sight is a fantastic sight. What would put it over the top would be the addition of a riser that Oversight Shooting Technology could include with the sight. I can't see using the See All Open Sight Mk2 on the AR platform without a riser. It would make it ready to out of the box, but it is only a $30 fix to buy a riser.

    1. I’ve got two of these worthless pieces of junk. I bought them on YOUR recommendation several years ago. They are cheap pieces of crap. Neither one EVER glowed in the dark or was usable in daylight for that matter. One of them wouldn’t even go onto the rail of any of my rifles. I won’t be buying anything else you recommend either, since it is obvious that you are just a shill for these junk-producing garage industries. You should be ashamed of yourself.

        1. Well, I thought that I was buying the tritium version since the two sights cost over $400 bucks with shipping. Maybe they sent the wrong ones, but they never glowed in the dark and certainly weren’t tritium anything. Couldn’t get them to even answer my emails. The one that wouldn’t go on a SCAR rail went in the trash. I gave the other one to a friend for his son’s 22LR. He never bothered to mount it, and it is sitting in a drawer in his garage right now. I own four Trijicon dual-illum RMRs, two ACOGs, and a Trijicon Accupoint scope and I know what tritium should look like. These didn’t have it. And, I don’t usually “go cheap” on anything. I still have an old Armson OEG tritium day-night sight on my crossbow since 1986, and the tritium didn’t even need replacement until 2006. Sent it back to Armson for replacement. $30, and no dramas. Still works fine.

        2. Oh, and I see they changed the mount. The old one needed to be slid onto a rail from the front or back. Tell me I went cheap on that too.
