Product Description

Machined from lightweight, extremely durable 7075 aluminum, Mil-Spec hard anodized Same height above bore as standard-issue M4 / M16A4 sights 1/2 MOA elevation and windage adjustments Ambidextrous sights easily and securely mount to Picatinny rails using a flathead screwdriver Low-profile sights extend only .2" above top rail, don't interfere with primary optics or military IR illuminator /laser sight Not anymore. Rapid Transition Sights (RTS) provide shooters with the quickest possible transition between longer- and closer-range target acquisition, greatly increasing their efficiency and effectiveness in battle and competition. These sights mount directly to a weapon's Picatinny rail, offset from center by approximately 45 Degree. This unique offset position makes transitioning from optical to iron sights simply a matter of quickly canting the weapon with your wrists and locking on to the target. There's no removing a hand from the weapon or making a manual adjustment, and no cluttered field of vision or iron sights blocking the optical sight. Just smooth, quick transitions that could mean the difference between winning or losing a competition, or more importantly - a gunfight. Weight: Rear sight - 3 ounces (85g) / Front sight - 1.5 ounces (44g).

Great functionality. Fair fit and finish. Crummy fasteners.

I wouldn't use these on a duty weapon or a primary combat weapon. I think they are just right for plinking at the range, entry to intermediate level competition, and hunting and predator control.

I own two sets and don't regret buying or installing them. However:

I would pay double the $25 these get for a set that had a rigid, non-wobbly rear sight block, firm, positive elevation and windage detents on the rear, and a durable, FLAT black finish.

These are not SIMILAR to the DUEK SIGHT SYSTEM, they are a blatent patent rip off and DAMN WELL WORTH THE MONEY!!
BUY THESE NOW BEFORE THEY STOP SELLING THEM FOR PATENT INFRINGEMENT AND YOU ARE FORCED TO SPEND NEAR 300 DOLLARS FOR THE SAME EXACT THING..........THESE ARE AWESOME!

They serve as both back up iron sights and threat interdiction sights like the xs sight system because they dont fold down or flip up so they are always ready. Like i said, the design is perfect because it is the DUEK sight system for 1 tenth the cost, buy them now while you can because i do not see how it is possible for them to even make now without be sued for patent infringement, but you know who wins when something like this happens though..........THE CUSTOMER if they are smart enough to realize whats happening and take advantage of the opportunity while they can and these sights are available at this PRICE!!!

Okay the GDT AR15 Rapid Transition BUIS Backup Iron Sights sold by KKMALL are great (WARNING: see below). They are Solid aluminum with a black oxide finish. Tried to scratch it with my knife, no damage. The screws are button head straight slot as one reviewer said but so are the ones on the Dueck angled sights. Wobble? Not these! Front sight index pin loose? Not unless you completely screw the post out. Haven't tried the Trijicon Tritium post in it since I don't own one. Won't fit Picatinny rail? Fits mine nice and tight and slips under my low mount scope. Haven't gone to the range yet to check their alignment but the rear sight adjusts left to right the full width of the mount with no problems so I don't see a problem in that area. The rear sight apertures flip solidly back and forth with no slop or play.

Update to the above: my sights were sold by KKMALL the bad sights were sold by POP!SHOP.

A friend of mine ordered these after seeing the ones I received; the ones he received are garbage!! Okay, there are obviously two different examples of these sights being sold under the same order page. Differences we noted: the mount screw is an allen head not straight slot, the front sight post is much larger and is VERY loose, the rear windage adjustment knob is hokey at best, the whole rear sight is loose and wobbly. I apologize to anyone else who I may have slighted by my first review. The second set IS GARBAGE, I wouldn't use them on my paintball gun.

I'm still leaving the 5 stars for the fist set as they are great. I hope Amazon can sort these out.

Right out of the box there is a ball bearing ready to fall out from behind the windage knob on the rear sight. I uploaded a photo to "Customer Images" if you are interested in looking. I guess quality control was asleep when this sight rolled past, there is no way it should have ever left the factory. Good news is Amazon returns are pretty effortless. Need to decide if I want to roll the dice again.......

Sights are well made and fit my rail perfectly. After about 250 rounds everything is still tight. With my buttstock it is a very comfortable transition between being upright and scoped and rotated the 45 degrees to use them. I would definately recommend.

The front site looked OK and the rear site mounted nicely. The elevation will not adjust all the way down to zero. When the elevation is adjusted up the site starts flopping around...like a bobble head. The windage will not go all the way left or right and damn near impossible. I have UTG iron site, and PSA sites and PSA sites with handle. Nice and tight and fully adjustable.

One reviewer was able to determine which set of these are the good ones, It appears there are more than one design being sold. The sites that have a "ALLEN" head to lock the sites down are the junk ones. The other set has "Button head with a slot" are the GOOD ONES!!

If you have the button head version with the slot please post which seller has them.

If your one of the sellers please check your stock and if you have the good ones with the button head. PLease change your listing so people know to buy the good ones. More sales for you.

I don't know if I've got a new model or something but mine don't have the philips screws it came with allen screws , once you tight them up those sights won't move anywhere ! super sturdy and all iron sights! i don't know where other reviews came up with some parts are plastic , at least mine aren't ! the color and finish almost matches perfect my Adams Arms Gas Piston AR15 ! I will keep you posted as soon as i go to the range but so far I'm more than happy for this sights and for the price ! is just amazing !
