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 wonky gas block with a hole drilled from the gas port through the top.  

Step 1: slide it on the barrel.

Step 2: look through the top and center it on the gas port.

step 3: tighten the hex screw to hold it in place 

step 4. drill a shallow dimple in the barrel through the open set screw hole. 

Simple as that!

 

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