Smallest .875 gas block?

Thank you for the education :)

You are all right. This is my first CF barrel and I did not notice the solid section.

If I go that route, I am going to have to find a gunsmith as that job is beyond my skillset.

Any chance someone here knows a reputable gunsmith in the Fort Smith AR or Poteau OK areas? The last one I tried here damaged an expensive barrel.....
 
Its extremely easy. If its a proof prefit barrel then it already has the first dimple.

Install gas block, install first set screw.
Then take a drill bit slightly smaller than the ID of the set screw hold and just dimple the barrel. You are just creating a crater for the set screw to seat so the block cant rotate. Then loctite the screws and torque down.

Install the gas tube and slide into upper.

The barrel is dimpled for a setscrew gas block. The question was about drilling for a pinned gas block.

If I opt to go with the setscrew attachment, I can do that myself. Probably use Rocksett instead of Loctite though.

Thanks
 
Yea pinned is pretty much obsolete at this point. Its only done on hard use military rifles like the M4/M16 and really is not needed on a precision rifle. Set screw loctighted is not going to move or turn like a clamped will. It also makes it almost impossible to install the block incorrectly, as the gas port will be lined up with the block hole, unless your barrel is drilled incorrectly.

Makes sense.

Set screw attached Superlative gas block.

I can do that :)

I am going to stick with Rocksett on the threads. Gas block can get hot enough to soften Loctite.

Thanks Everyone
