SeeAll Rifle of Rail Tritium Night Sight -

Why we claim our tritium sights are the best night sights on the market:

Exciting Dual Illumination Integration:

Low to Full Light: Edge Glow Polycarbonate - This light gathering technology ensures full reticle visibility when shooting from low to full light conditions.

Tritium Inlay - This patented setup allows for reticle visibility in even the darkest of nights without causing night blindness. No batteries required... ever. Our tritium is always the highest quality and outlasts the competition by as much as 4 to 5 times longer. 

Constructed for Maximum Durability and Quality:

100% made in the USA

Anodized 6160 Aluminum body for both strength and corrosion resistance

High strength polycarbonate "guts" to prevent scratching and temperature warping

We build our products to last. One of our first tests for durability was to drop a mounted sight with pistol from 6' to hard concrete. The result - perfectly usable!

Unmatched Designed for Superior Performance:

Lifetime Warranty: With multiple patents and a lifetime warranty on parts, we stand behind our claims that this is the best tritium rifle sight on the market.

Holds Zero: Our patented Micro-Adjust system with multiple hard spring placement ensures our sights hold zero in every situation.

True Clarity: The SeeAll no-gap construction method prevents hazing, fogging and scratching. This means you'll have a clear site picture every time and in every environment.

No Parallax: Unlike other sights, where you see the reticle is where your round will hit. Regardless of your angle or eye position you'll hit where you aim.

Mk2 - Tritium Night Sight Rail Mounted

Nice optic

I purchased the SeeAll sight because my AR pistol cannot mount a front sight, and after a couple different optics that let me down I decided to try it and am impressed so far. Only complaint is that it doesn't mount securely to a picatinny rail, it has space to move back and forth and will require a spacer of some sort.

impressed so far does take some getting use to but once sighted in will make open sight shooting ...

impressed so far does take some getting use to but once sighted in will make open sight shooting a lot easier.

very good sight

I installed it on my AR and it works very well if you don’t care about magnifying. it was to be a 100 yard shooter anyway, does great

tritium seeall sight m2

I am in my mid 50s and recently had problems focusing on the front and rear sight when not using a scope. This has solved the problem. It takes a while to get used to shooting using the seeall sight but for short to medium distance shooting, this sight is great.
