Only one problem I had with it

So I got the sight last year for a rifle and it’s a great sight. The only issue that I have with it is that it requires an allen key to adjust both hight and windage, like almost every other tritium/fiber optic sight. So if I need to make adjustments to shoot at a further target or if my friends need to adjust the sight, I need to bring an allen key.

Just wish it had knobs or something similar to make sight adjustment easier.

Tritium Delta

Fast shipping. Easy install. Perfect for a PDW. Heads up both eyes open. Quick on target. Center mass - every shot.

Sight Works Well, Adjustment Instructions Need Work

I mounted this on a 1in riser on a new AR pistol in 300BLK. I started to zero at 25 yards. I was used the instructions from the video to make my what I thought was about half of the necessary adjustment. I ended up off the paper. I unmounted the sight, visually centered the windage, took out the elevation turns I put in, and re-mounted the sight. I moved in to 10 yards and was on paper again. This time I was able to make the adjustments. I got 6.5 inches of impact movement at 10 yards per full turn. I believe the video cites 1/8 turn produces 1/4 inch movement at 100 yards. I think it is really more like 8 inches at 100 yards. The video could use a correction or clarification.
As for shooting with it, it works well! It was good shooting from a rest for zeroing, and pretty easy to use shooting offhand with a range of eye relief. I am not accustomed enough to it to be fast, but I think speed will come with practice. I'm glad I decided to try this out.

Almost a great sight.

I have started to get comfortable with this sight and was shooting as well as a red/green dot sight or fiber optic open sights. The one thing preventing me from purchasing any more is the mounting. My gun collection is made up of break barrel air rifles. Those guns all have an 11mm dovetail rail. Any future purchase of a SeeAll will require a direct 11mm mounting without needing an adapter. It is a great sight… almost !

Smaller size

I do like the MK2 better than it’s predecessor because of the size. I would have preferred the crosshair over the triangle but the price difference was way to much to justify buying the crosshair type.
