Are you the type of person who likes to take care of business yourself and want to do it right? Well, here is a case where doing it the right way requires the right tools. For a lot of us shooting, amateur Gunsmithing, and doing things ourselves is more than a hobby, it's a way of life.

Attention To Detail

Do you really have to dimple your barrel in order to install a gas block? Well no, but you don't have to tie your shoes either. In this case, an AR barrel dimpling jig is a must have in order to do the job right. If that gas block is just a degree off, you will run into FTE or FTF issues at the least, in the other extreme the gas block and gas tube could come off. With gas block alignment, almost isn't good enough. One way to make sure that your alignment is good enough is by using a KVP Gas Block Dimpling Jig to do the job right. This professional grade jig is crafted from hardened steel and has precision machined guide holes so you can get it right the first time.

The Right Tool For The Right Job

Just why do you need another tool? Because you can never have enough toys. An AR barrel dimpling jig may hang out in your toolbox for a while until you decide to change your setup and then you are going to need it. The time will come when you upgrade to a new barrel or a better gas block and in order to make things right, your KVP Gas Block Dimpling Jig will be there.

  • Awsome

    I wish I had this thing when I first started building ARs. Super easy and precise to use, perfectly aligned gas block every time. My only complaint is that it doesn’t have .485 spacing for an Aero Precision gas block I have, but you can still use it to drill a single dimple opposite the gas port which is 1000% better than nothing. Also it might seem like 5/32” drill bit doesn’t fit, but I assure you that it is the correct size, the tolerances are just very tight.

    Well-finished, precisely locates gas port.
    Drill Hole does NOT accept 5/32" drill bit.

  • Good for Quick Work

    The fit and finish on this jigs is pretty good. These will last nearly forever for a home shop (a commercial shop should probably have a milling machine).

    I'm really only knocking these a little. The inside of the jig is necessarily a little larger than the journal. That means using a single set screw apart from the alignment screw will tilt the jig. Getting two or three more set screws, would allow you to fix the jig closer to concentric to the journal.

    Is this a major problem for the precision required for a gas black? Probably not. But, for another fifty cents, they could toss in a few more set screws just for some additional confidence when dimpling an expensive barrel.

    The jig works awsome. I like the fact that it has multiple sizes makes it so much more versatile. Wing Tactical is an awsome place to get your supplies. They take care of their customers. Will order from them again

  • Excellent Must Have for Builds!!!

    Overall it does what its suppose to. If youre going to dimple your barrel for your block (which I prefer) it makes the job much easier. I wish you could see how far you were drilling a little easier, not sure how they'd do that to be honest, but it would be nice. There are some gas blocks that are .485" so they fall right between the .470 and .500 pre spaced slots, little hand drilling it works just fine.

    Overall highly recommend.

    works as expected, simple to use, would be nice if they would include the 1/8 drill bit.

  • great tool

    so easy to use followed a video i saw, would be better if it came with some instructions that's the only reason it didn't get 5 stars
