Mk3 Mounting Options

The Mk3 Tritium Lit Sight mounts using the most widely used optic plate offered. THE RMR CUT. Place the sight onto the RMR optics plate cut, insert the two screws on either side, and you are ready to go! Yes it can be mounted in the time it took you to read the steps! Also we bore sight the sights before they are packaged, so you will only have to make small adjustments. Does NOT work on the new RMRcc Cut. 

Dual Illumination 

What is dual illumination? Dual Illumination is when you have two sources of light in a single sight. Our Mk3 Tritium Lit Sight has been redesigned to have the most edge glow light gathering material we have ever offered. This edge glow will take light from all directions, and transmit that light to your reticles edge. This new design works so well that if you have any light (even a full moon) hitting the sight you will be able to see the reticle. The second part of that dual illumination is our patented tritium placement. We have a vile of tritium directly behind the reticle that will give you the same bright sight picture as you had during the day! A true battery free 24 hour sight!!

SeeAll VS Micro Red-Dot

Why buy a SeeAll Over a red dot? Well there are a lot of reasons, and here are a few of them! 

Our Sight weighs under 1 ounce, red dots weigh over a ounce

Our Sight has no electronics, or batteries. Red dot sights have these unreliable parts. 

Our Sight is constructed out of anodized aluminum, and acrylic ready for anything you might put it through. Red dots are made out of plastic. 

This Mk3 Pistol Sight is the smallest sight in its class only measuring 1 inch wide, 1.8 inches long, and only .58 inches tall. Usually closer to .48 tall when you mount the sight into an optics cut!

Our Sight is fully adjustable, and unlike a red dot you can aim off the point of the delta. Rather than covering your point of impact with a big red dot. 

 

Our Sight has a built in racking point making a quick, and easy experience when using it for speed, or simple plinking. 

Finally Oversight Shooting offers a lifetime warranty on our products, because they are built to work, last, and perform!

Body is constructed of a CNC cut 6061 aluminum that has been anodized

Guts, and optic are acrylic for the best lighting, and durability

Great Sight

I am very new to shooting with a sight but found this to be an easy adaptation. Very tight grouping on my shots. Would have been way easier to have the adaptor plate included but other than that great product.

Takes a little while to get use to finding the sight triangle, not for quick sighting. The mounting plate screws are a little short, needed to be about 1/16" longer. Do like the product, will order again, in the future.

Great sight, durable, no batteries, tactical. However target acquisition seems to be a little more difficult compared to regular night sights. I’ve read it’s because of the micros smaller size. Overall a great product.

Quite good with room for improvement

The sight arrived safely within 17 days to Germany. I chose the Delta reticle. I like the principle of this sight really much. However, it really needs training to find the reticle quickly on a pistol. Often you'll find yourself searching it in the edge glow material. I wish there was done something that guides the eye towards the tip of the triangle (maybe a few tiny lines on the edge glow material pointing into the direction of the reticle's tip).
Additionally, when my pistol-holding arm is stretched out completely the reticle is magnified so much that it fills out a lot of the "window". This makes it sometimes even harder to correctly establish a good aim because all I see is black. Decreasing the reticle size or increasing the lense size a tad might be enough to fix (I know, bigger lense might result in a too bulky sight for a pistol).
I also mounted the SeeAllOpenSight Mk3 onto my AR15 using an RMR Picatinny plate. I must say, on a rifle it's excellent! Here a bigger lense would be more justifiable...
The edge glow material on my sight has a tiny inclusion around the reticle, which bugs me a bit. I also wish the tritium vial was perfectly centered behind the reticle. I will have to live with these little production flaws.
Although my review may seem very "fault-finding", all in all, I can recommend trying out this sighting system! I will for sure invest more training to become proficient in shooting with it on my guns.
I am looking forward to seeing the next evolution of SeeAll's open sights! Great job so far, guys :)
