This thing is awesome!
I like it wish the R was not so easily seen
Its very well made but I am havein a hard time seeing through it.
This the best open sight on the market I call it the precision open sight
Easy to use and adjust great addition to my AR Pistol i needed a spacer to make it comfortable but they recommend u do it in the directions for AR's even got 2 day shipping and it didnt get there in the 2 days and they refunded my shipping fee. So im very happy with it.
