Very impressed

For those of you gamers, it's like using the HCOG Bruiser from Apex Legends.

This sight is so unique, and allows for a totally open picture. With no top, you can easily acquire targets with both eyes open. This is the simplest yet most intricate sight I've seen yet. Reliability on this sight is huge, as it doesn't require any power to produce a sight picture. The only thing I would change is not requiring a magnifying lens, then reliability is totally maximized. I'd be worred about damaging or scratching the lens and impeding view. Other than that, awesome sight and I'll probably buy more!

Added to M&P 12 with 1" riser block. Doesn't take too long to get used to this sight. Shot better with it than using a red dot. If you have any kind of presbyopia then this sight will make you feel a lot younger. The ease of re-acquiring over a red dot made this worth the money not to mention less bulky and low tech.

I purchased the MK2 sight mounted it directly to an AR pistol it was a little too low for me so I remounted it onto a 1” riser and I am very happy with it.
I’m going to sell the red dot and buy the MK-1 open sight for my Kel Tec sub2000.
The best part about it for me is I don’t have to turn it on and off or mess with brightness settings, the SeeAll with tritium is ready day or night.

Put this on a Drako AK pistol. boresighted it and went to the range. I was bouncing 20 soda bottles at 125 yrds 4inch groups at 100yrds on paper. a lot of fun quick to pick up the triangle. I think I'm going to put the next one on my Ruger 10/22 . Sounds like fun for all!
