WARMINSTER, Pa. -(Ammoland.com)- This is a step that many builders skip due to the fact that locating the proper location to drill the dimples can be a difficult and nerve-racking task.
Putting the dimple in the wrong place can mean having to go with a different style gas block or in a worst case scenario, ruining your barrel. We feel that ensuring a gas block cannot move is essential in the continued reliability of your AR platform.
EZ Accuracy AR-15 Gas Block Dimple Tool
While there are tools on the market that accomplish this task, they are all proprietary to a certain gas block. Unless you are a shop that always use the same gas block, it’s not very economical to spend money on the tool.
As a shop that installs a large variety of gas blocks, EZ Accuracy came up with a simple and fast way to install any block that uses a 10-32 sized screw.
“Gas blocks are very easy to slide onto the barrel but can become tricky when machining so that the block will not shift. Many AR builders will skip this step out of fear of placing the dimple in the wrong place. I have used this method for years and I’m now offering the tools at a price that’s a fraction of the price of gas block tools available on the market”, says Eric Feldman, owner and gunsmith at EZ Accuracy.
Using this system is simple. Install your gas block using the manufactures instructions. When you are sure the block is in the proper location, remove one set screw and install the EZ Accuracy screw.
From here you can slide the supplied marking pin through the center of the screw and tap to center punch the dimple location. Now you can remove the marking pin and lightly drill through the screw using a 1/8” drill bit.
When you have your dimple, replace the set screw and repeat with the remaining set screws until complete. At $14 with free shipping, the tool is well worth checking out.
It is available on Amazon and directly from EZ Accuracy’s website.
Take one of the sets screw our and replace with a same thread,reshaped to a point screw, tighten to mark the barrel. Make two and mark the second while the first is still tight against the barrel. take the sight off, tap marked divots with center punch and drill. Price MAYBE a dollar. Use a high grade hardened screw. Put the saved $13.00 into another mag or ammo.
