"Guntec USA all the way! I ordered this flip sight and a Guntec quad rail for my Palmetto PA15. Awesome quality, incredible prices, and the fact that the sight locks in place once up is nice. This is currently the main sight on the rifle, and it works just like the old hand rail sights on the M16A2/A4s that I used when I was in the infantry. I wouldn't say it's as low profile as the Magpul's. Would I trust the quality of the sight with my life? Yes. I have yet to equip a scope/CCO of any type to see if the lay down height interferes with the sight picture. I have serious doubts it would be an issue with an Aimpoint or scope, but it could be an issue with an NcStar/EOTech type CCO (but I doubt it). Wish I had more info on that. I can tell you for the price and quality, it's a good buy to get up and ready to shoot."
"Just received the rear Guntec back sight today. In 4 days it was shipped an arrived. Very fast thanks CTD! I open the package and there was a little box with my rear sight. I opened it and put it on. Once in place it was locked down and ready to try. It was all metal like the expensive Troy battle sights with two flip up sight pictures. It was one the mark at 25 yards. Very nice rear sight, very sturdy and very nice. I'm thinking of getting another one for my other AR15. I'm very pleased."

"Ordered this for backup sights. My order came in rather quick and the quality was better then I expected for the price. I am pleased with the products that Cheaper Than Dirt has to offer. Thanks."
"An all metal sight just like the expensive ones with two flip up apertures. Folds down nicely and therefore works great with my red dot scope. Using on an AR15 7.62x39 I recently built. Very Happy. Thank you CTD."
"I purchased this flip sight for a newly purchased AR and I must say the fitment and workmanship are both excellent. I only shot about 50 rounds and was well pleased with the accuracy of the rifle in conjunction with these sights. I would recommend this item if it's open sights you want. I will be getting a scope as well but the flip sight will definitely be on board."
