Great Sights


For some reason this site was extremely hard to get onto my rail I had to tap it on with a hammer. I took 1 star off for difficulty mounting. Aside from the mounting, it is great. I really like the fact that the front sight post glows. Along with the horizontal line on the rear sight it makes picking up your sights in the dark much easier.

Great product, great price


I searched amazon and other sites and it was cheaper here than anywhere else, even after shipping. They shipped it the next morning and I had it in a couple days through regular mail. Great sight, couldn't find a negative review.

Does the job


Other than that the contrast definitely enables for low light aiming and higher contrast for dark targets. Night brite is what it says. Bright when charged with a tac light. Definitely satisfied.

Competitively Priced Sights [front & rear]


These Sights are fairly sturdy. For plastic - - Sorry "Polymer" materials, the design and manufacture of this product is about as good as the very well know, Magpul-MBUS products, and not very different in price. You may prefer the geometry of these diamond shaped sighting pieces too. They have a spring loaded deployment mechanism.

Great alternative to Magpul polymer sights


These things work and look great. Better than Magpul's IMO.
