Gas block pinning service is offered on all low profile gas blocks that we sell. Gas block pinning, while not required on a properly installed gas block, adds extra layer of assurance that the block wont move after installation. Normally gas block pinning is only needed where the gas block is exposed to external impact, but it can be done on almost any low profile gas block if requested.
We offer a heavy duty stainless steel coil pin by default. We can also use a taper pin if If you think you will need to remove the pin at some point.
In order to pin your gas block, we will need the following:
- Barrel
- Gas Block
- Barrel nut
If your barrel nut is proprietary for your rail, we will need it since the gas block will need to be done after it is in place. Some rails utilize the standard USGI barrel nut. If your rail does, you have the option of purchasing one from us.
If we are installing a set screw type gas block, we will also dimple the barrel as part of this service.

This service is top notch. Alex can take any gas block you have and pin it perfectly. I had him pin a couple of Daniel Defense Crane MK12 gas blocks (which are larger than your average block and have unusual dimensions) which came out perfect. I even specified I wanted none of the pin sticking out the sides of the block, like some companies do (which I just think is ugly and would be a no-go under a tight DD RIS II). He did exactly what I asked and it looked great with a sturdy 1/8” heavy duty stainless steel coil pin. Plus he will inspect everything with gauges to make sure your barrel is good to go before pinning. I know of no other gunsmith online who will do this. Not only that but each screw is properly torqued and set with thread locker. You know your gas block ain’t moving after this. Couldn’t ask for better! Definitely recommend Trajectory Arms for sure! Thanks Alex!
