Want to dimple your ar15 barrel 180 degrees from the gas port but don’t want to waste money on a tool that costs a bunch of money? Use this instead!  This no-frills gadget will help you figure out where to drill that dimple for your gas block set screw if you’ve got a barrel with no dimple.  

It’s just a gas block with a hole drilled from the gas port through the top.  Comes with a pointy set screw for centering on the gas port.  

Step 1: slide it on the barrel.

Step 2: Center pointy screw on gas port and tighten

step 3: drill a shallow dimple through the gas block hole on opposite side of gas port (180 degrees from the gas port)

Simple as that!  You only need one dimple, 180 degrees from the gas port, and it should work for any gas block.  Virtually all set screw gas blocks have a set screw that is 180 degrees from the gas port. 

 

note: you could maybe use this as an actual gas block, too.. but we wouldn’t necessarily recommend it.

    Worked great – Used it on an upper that previously had an FSB and did not have a dimple. Simple super and quick. Coupled with the knurled set screws Mid State offers, I feel very confident in my gas block.

  2. Stacy Parker (verified owner)

    Cheap ass gas block. – Beyond happy with this purchase. Wow, words can’t express how much I needed this in my tool chest. Thank you Mid State fire arms, for having it here in a week. I live in maui, the shipping was beyond fast. I can’t say how much I appreciate everything you have done for me, Mahalo and aloha.

    Every AR toolbox should have one of these. The only thing cheap about this was the price, very high quality, should last for years. Used a cheapo drill press with a 5/32 cobalt bit, and the results were perfect. Thanks, Midstatefirearms, for a great item.

    Critical for proper set screw placement – I have built rifles for 30 years now. The older barrels were not dimpled for proper set screw placement so you had to figure a way to place them properly hit or miss. This device allows you to place the dimples for the set screws in EXACTLY the proper place the first time. It is a godsend for DIY’ers, I bought 2 of them!

    Awesome – This thing is pretty fu**ing awesome! Worked great but don’t rush when using it. Even the quality of the metal is good so on my next build I will be buying there actual gas block. Even came with a bad ass Koozie so I’m definitely happy! Saved about $20 on not buying an actual jig.

  5. CC

    Works perfectly – Works as intended and couldn’t be easier to use. Great price, too!!
