Green Blob Outdoors Premium Military, Mil Spec Flip Up, Folding, Front and Rear Iron Sights Tactical Set for Picatinny / Weaver Rails Flattop

Easy to install at a good price.

Very pleased with the product considering the cost. They were delivered way faster than expected, and I'm very pleased with the quality and finish. It would be nice if there was a pin that kept them from flipping up, similar to the pin they have that locks it in place when the sights are folded up. My concern is that after extended use of the firearm, the sights may become loose and flop up when I don't want them to. (I'm using these as BUIS) But, considering the price I guess I can't complain. This review is after my initial sight-in and I haven't had a chance to make modifications yet.I sighted it in at close range (~35 yds) and in order to do so the front sight pretty much all the way down, and I would've preferred to have the sights zeroed in at a further distance (50 yds min) (I haven't moved back to that distance yet, so I can't say for sure) and I'm afraid I won't be able to lower the front sight post more as I move back. A bigger issue though, is that with the front sight post as low as I have it, I can't fold the front sight post down. Having the front sight post as low as I do seems to be the culprit of that. These are intended to be my back up sights, so unless I can incorporate the front sight with my optic, this will be an issue.On the rear sight as I was transitioning between the small peep hole and the large peep hole, I noticed the small peep caused me to shoot high left. This is because the peep hole rotates on the thread. You can compensate for it by rotating the wind age adjustment in the same direction as the rotation of the peep. (At the distance I was at it was 3 clicks). I wasn't fond of the way the small peep lined up (due to personal preference only, my friend I was sighting in with preferred that one) and since I plan on attaching a scope, I figure I just won't be switching between the 2 peeps. So I guess I can live with that, but it may be something to bear in mind if you intend on using both peeps.This review is after my initial sighting in of the sights, so I can't speak to anything else yet. But these are my first impressions, and I figure they can be helpful.

Actually made of decent metal basic but functional actually stay in position you put them in. They Don't fold up suddenly unexpectedly . Not bad at all for under $20

Before reading my review, take a look at my picture. These are NOT the sights I received....This is the STOCK IMAGE that they're using to advertise. I added some perfectly vertical red lines for reference. These images SHOULD be a perfect example of the best of their product. The front sight is admittedly not too bad. Mine came a little worse than this but not awful. However, look at the rear sight. You can see how the top of the middle portion is angled to the left. Mine came worse than this. You will also notice that the white lines used for adjustment are not pictured straight on. (Deliberate perhaps?) When viewing the angle of the sight in combination with the white adjustment lines, the misalignment is painfully obvious.I cannot stress this enough: Buying these sights is so much of a risk and gamble it is a complete waste of your time. I received mine fairly quickly which I appreciate, but the front sight was imperfect. Not bad, but not perfect. Front post was off just a tad. But I could live with it. However the rear sight was so off, the top adjustable vertical line was at an angle. Badly. And yes there were some imperfections in the metal work here and there, but nothing deal-breaking. So I contacted the company and they promptly sent me out a replacement, which again, I appreciate. They also sent me new front and rear sights which I also appreciated because I only asked for rear. This time, the front sight was fine. But the rear sight was off again. The adjusting screw is machined at a poor angle and it throws everything off completely.Perhaps this company produces perfect sights every 5 out of 10 times or maybe 2 out of 10 times. Seeing the 5 star reviews here, apparently some folks are getting decent sights (or they just arent inspecting them well). Ether way, are you willing to take that risk? I'm not. It was a waste of my time. I'm currently putting in for an A-Z Amazon claim (THANK YOU AMAZON for providing this feature).I do want to mention that I sent Green Blob an email and challenged them to ramp up their quality control. If they machined things properly, they would really have a pretty good thing going. Sad to see this as such a missed opportunity for them.

Purchased these recently. They fit well on the Seekins BAR rail for my pistol AR. On first glance the feel like a quality part. When mounted they don't wiggle or move about on the rail. They aren't spring loaded so you have to push them up but when they are up they click into place. If you apply backward pressure the sights move slightly but will stay straight up otherwise. To put them back down you simply hit the lever and fold down. Very simple design and does not add a bunch of unneeded weight. They are not as small as some of the other flip sights on the market but they are small enough IMO and for $25 they will do just fine. Overall they are an excellent value... No they are not as nice as the $200 Midwest industries, Magpul, Troy or Diamondback steel sights but they are far better than the polymer Magpul sights they are replacing. For $25 you get sights that would be a good deal at a $75-$100 price point. If you spent a couple grand on your rifle then by all means get top quality sights but if you want some almost as good sights for a fraction of the price for your non operator, non marksmen grade rifle then these will fit the bill.
