Chaos Ready | Flip Up Iron Sights - Spring Loaded Low Profile Back up Ironsights | Designed for Picatinny 1913 Pattern Rails | Co-Witness Front and Rear BUIS Combo Set |

Well made and easy to install.

Very nice easy install. Seems pretty sturdy. Was on target out of the box. Very happy

Overall out of the box they felt good but the bolt twisted in half when I installed them for the first time. It is covered by a lifetime warranty and it's not a pressing need for me but it is quite inconvenient. Otherwise, felt solid and deploys with authority. I will update review upon replacement.Update:New set came in after a couple days. Didn't have the same issue. Holds zero and feels great for the price. Can't give it 5 stars because I had issues but everything else about it screams 5 stars.

Seems to be well machined. No sharp edges, I would like if corners were a bit more 'dulled out' or rounded off, but there's nothing sharp enough to cut you or tear skin bumping into it.

Decent set of BUIS, now need to get some time on them to see how they do on the long haul.

First, I haven't put enough rounds through this to know its longevity. Thus far it works. I like having back up irons on my firearms and I prefer the ability to cowitness. However, I have always been a "small peep sight guy." When I flip up my irons I want to use the small peep. So the first thing for me that I dislike is the sights are set up to primarily use the large peep sight aperture. If this is something you like then this won't be an issue. But when in the folded position the sight won't sit flush with the receiver unless the sights are in the large aperture position. So when I flip sights up I have to switch the to the small aperture. Second there is only a center notch on the windage adjustment and not small notches for reference. So doing the old method of counting how many clicks across the entire windage adjustment then going half way will be the method to use when doing mechanical zero then to start the zeroing process. Otherwise the sights are snug, thus far feel quality, and held their position for 50 rounds, time will tell if holds up beyond that. For the price, this is a great set up to put BUIS on your rifle. I'm comfortable enough to keep them on the rifle and trust if BUIS is necessary.

They are very solid sights, they shipped very quick and for the price they definitely top the magpul sights that cost twice the $ easy to install, high quality material no question of stability function as they should and look sweet

These are solid metal with heavy spring tension. They are heavy (well made) and are perfect for a back up optic. I compared them to magpul a buddy has. If I’m nit-picking I could say there is a little play in the rear optic when it’s up and in the front sight post, compared to magpul. HOWEVER, the spring tension on everything keep both in position in the same setting. There’s really no chance for them to move. I checked and rechecked flipping them up at 50 yards on a 10.5” barrel and it remained steadfast and was able to hit a 1” bullseye easily. They clamp solid to the rail and are a snug fit. I would it these again. Less than half the price of magpul, you won’t go wrong.
