Question: Will this sight line up with a standard carrying handle when mounted on an even plain gas block?
Document: This front sight is the proper height for mounting on a railed forearm. It should not be mounted on a railed gas block due to the lower height. Overall quality is excellent...deep, black parkerized appearance with clean, crisp edges. The large, rounded thumbscrew cinches up tight...sight to rail fit is perfect. This is a definite &#34;would buy again&#34; purchase!
I have a MP15 flat top and the gas block I thought was a bit high. Once I changed to a quad rail it was even all the was across. It was a perfect fit and height of the low profile front was right on. Very secure.
This product is well made and the finish is just fine. YOU CANNOT USE THIS ON LOW PROFILE GAS BLOCKS! My only issue with this product is that it is made slightly longer than a standard gas block so it hangs off the front or rear about 3/8 to 1/2 inch which in my case HAD to be the front.
This sight worked well with my detachable handle rear site system, I gave is 4 star rating only because its a bit bulky and heavier  than I expected. However the weight makes it very durable and rock solid when mounted on the gun.
At first I was hesitant to buy this because all the photo's I had seen seemed "off". Got it, mounted it on my DPMS Sportical and it was just what I was looking for. Along with the carry handle this made my flat top the twin to the "Black Gun" I have always wanted. Fit right on out of the box with no problems.
Perfect sight to replace the a2 style after going with a low profile gas block. Works great with UTG rear sight.
A sight to go on a gas block for a flat top or to put on a rail that is at the same level as your rear sight block. It works and took only minor adjustments to zero in.
The front sight by UTG is sturdy and reliable and it seems to hold zero however it does not work with a low profille gas block and the thread is not standered so changing the sight out is not possible but its a solid sight with no problems
Bought this to mount on my Adams Arms gas block which is level with my receiver rail, perfect fit. The sight is shorter than the gas block rail but this is not an issue of any kind. Would highly recommend to a friend.
good sight,use with utg match rear sight if front rail at same height as rear rail. if mil spec rail gas block,use tower front sight not low profile
