Question: will this work on sig 522
Document: is a great sight, I put on my m400 Sig Sauer. the price is the best I got on the market, I recommend them
Very excited never even taken a 300 yard shot. They work even with old eyes.and the fit was great.
This item will not work for hand-guard rails that are level with the rear site rail. The description is misleading since it does not state this.
Nice sights for the money. I would buy again.Good people to deal with as well. Work very nice on my rifle.
easy to attach to any picatiny, easy install, you can switch between two ring sights and can adjust for both. solid milling work and very sturdy overall.
I was happy with the sight. The fit and finish were just fine. I hop that my EOTech does not fail and I need to use it, but I am sure it will work fine if I do.
if you use one of the higher rear sights perhaps with the full base to it with this sight it would probably work, but I would guess that it would defeat the purpose, since those don't fold.
I use this as a back up on my AR 10 and it works wonderfully. I didn't even need to adjust it once it was level. Does work better with a front sight tool. Cant adjust it with a round.
I know it does not say it in the description, but it IS built on mil-spec, so that mean it will work on you low profile picatinny gas blocks ( as long as they are mil-spec too ) Great product.
This front sight and companion rear sights from UTG are well made and a great value. Unfortunately, it wouldn't work on the SIG 556R and I had to return. Note also that the mounting screw is much larger than I expected.
Answer: yes
