Low Profile Gas Block Pinning Service

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.
