You may want to check out our MicroPin Gas Block.
http://www.blackrivertactical.com/co...pin-gas-block/
Its a precision fit gas block specifically designed to be easily pinned without a drill jig.
A flat face and center spot positively locate the drill bit in the optimal position.
It comes standard with those knurled screws and a spiral coil pin for extremely easy installation.
It can also be pinned with a taper pin or a straight pin using the appropriate reamer.

The knurled set-screws are the best choice this application, that's why we include them with the block.
The solid pins are stronger in terms of absolute strength, but the requirements for a gas block fall more in line with fixing the location, rather than transmitting torque, so maximum strength is not required.
If you like solid pins instead, we do offer a solid pinning kit for straight pins like Noveske uses.
The decision comes down to personal preference and ease of install.
The spiral coil pin works and is dead easy to install.
Just drill the hole and knock the pin in.
Taper pins and straight pins are slightly more difficult.
You need to drill an undersized hole, ream to size and then knock the pin in.
The solid pin reamer can just be run clean through, while the taper pin reamer needs to be reamed to a specific depth.
2/0 taper pins are commonly available in 3/4" length, which is a little long for low pro blocks, and must be trimmed or left long.
0.625" solid or coil pins are a perfect length.

Thank you for the outstanding reply, Clint.
Part of the reason that I didn't pull the trigger on the 87ind pinned block was that it used only one set screw. I'm sure that was ifne, but yours uses two screws, applying even downward pressure on the gas journal by the block even before the pin is in place. A good little bit of overkill as far as the gas seal goes.
Now that I understand the purpose of the pin, I'm sold. Thanks for speaking up.![]()

One thing to keep in mind for those that are contemplating using Loctite whether it be the red or retaining compound, set screws, etc.... At some point you may need to remove the gas block so I would make sure you understand what it takes to do it properly and understand what will be necessary to remove everything as well.
