Question: How long is this sight and how high does it sit off of the AR?
Document: This sight did not last very long before the reticle shifted to the far right and was no longer even on target. I had it working for about 3 mags and then it broke. Look for a different optic to fit your needs.
Nice fit for an AR. Easy knob selection between red and green. Have not had a chance to field test, will re-post after use.
I won an AR recently. it is additional to many i have. I needed an inexpensive scope that still provides quality optical sighting. this fits the bill.
easy to install its everything its advertized nice sight good for quick shootingin all light conditions worth the money
I love this sight , the red & green reticle do great job love the look on the gun and it's easy to sight in would buy again
Works welol and for what it is this is a heck of a deal. These things as for quick sight and shopot not for tight scope work. for Waht is is it is great and wortks well  Too many pe0ople think it is for sharp shoointg...if so buy a real scope not a reticle.
Super light gathering ability with green or red lit T-style reticle.Holds zero during the harshest treatment. Also includes a veryuseful top of the scope sight to make it a perfect Zombie stomp-er!
I used this scope one time at the range with my bushmaster AR 15,after one 30 round clip the inside lense flip around and it fell apart,i work offshore so amazon told me my window for returning it ran out,so when i get in i am going to try and contact the people who make this to make it right,pretty sad tho this scope was suppose to be mad just for an ar.
it fits my needs; great scope for close range.i price is on the money . am thinking of buying i second one.
Well built graphic is cool. Looking fwd to using it. Have it mounted on wifes ar15. Hope it holds out
Answer: yes
