    This is a gunsmith install only. There are two pilot holes, but they are only about 1mm deep or less. It would be best to install this on a new barrel that has never been pinned, so that you would get a good pin channel.

    May have been addressed elsewhere; the design has me curious. Why does it have rail slots on top? Cosmetics? What would possibly mount there? MM's review stetes "The rail on top of the gas block has been retained." Why?

    1. In case you decide you want a fixed front sight after all
    2. In case you decide you want to mount a fixed front sight on the rail and a flashlight on the gas block.

    Just because it has a flip-up front sight doesn't mean you need to use it, that's the beauty of keeping it railed.

    Those two reasons don't work for me; guess I'm too low speed.

    Also, if you have a scope mount that slides on from the front of the receiver and rail system, it will pass over the gas block as well.

    The second build I will be using another VST on will have midlength MOE handguards; I intend to use the top rail of the VST to attach a tac light when needed. The QD sling swivel inserts will also be of great utility on that build, since otherwise I would have to rely on the MOE polymer rails to add a sling swivel adapter.

    You can afford to have a KAC gas block/front sight sitting unused in the parts drawer!?!

    And likewise, if it was flat on top with no protrusion for rails then the mount would still slide right past...

    I had the older style and I liked it a lot. I do like how this one doesn't have the extra material mine had. Mine was EASY to flip up and perhaps this one is not as easy. It looked funky deployed though...

    the rail also gives you the option of mounting some other folding front sight on top of it if you don't like the sight picture provided by the vltor; a troy for example. you get the longer sight radius, plus a front sight that's mounted on the barrel (for those concerned with barrel or rail deflection under certain circumstances, and want the front sight to move with the barrel).
    anyways, it's there, but you don't have to use it (like QD sling cups in most stocks).

    The ears are now smaller but have deep serrations on the sides and it is easy to grip and flip.
