Most Helpful Positive Review XS Sight Systems standard dot for AR
This sight post perfectly compliments my rear peep sight. I am not a precision shooter, and rarely shoot past 150 yards. This product is perfect for those who use a carbine for home defense. It is quick to pick up. It is bright, but not too bright. I use the Big Dots for my pistols since those ...

Most Helpful Negative Review No light and way to small
Fiber optic front posts were tritium are very hard to find the ones that are out there are simply no good. This is no exception. This can hardly be seen in a totally dark area and outside doesn't glow at all.

Only 2 notches

by Romo, from TN, United States Written on November 13, 2025
The sight seems nice but when I replaced my post with this post on my back up sight it would only lock in sideways (90 degrees off). The problem was there were only two notches instead of 4. to lock the sight position in. Might be my sight is not standard but most AR sight posts come with 4 notches to lock the post in. Wrote this review to make buyers aware of this.

Glows In The Dark

by Jarhead, from CA, United States Written on May 10, 2023
Installed in MBUS backup in front of T2 Micro mounted at Absolute CoW If electronics go down the tube becomes an 18mm Ghost Ring. Nose to the charging handle, both eyes open picture doesn’t change. Flip up the sight and go. Installation is straightforward, though could be better. Not for precision shooting. See Cons below.
Pros:
  • Hi Viz in low light
Cons:
  • Installation would go smoother if it had only one detent notch. Only one is useable, why cut four? I suspect XS modified someone elses post.
  • 5 MOA Adjustment
Best Used for:
  • Home Defense
Would recommend: Yes
