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 an extra layer of assurance that the block wont move after installation. Normally pinning a gas block 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 you prefer however we find its easier for people to damage their barrels with these so we don’t typically recommend them.
Before pinning a gas block, we will need you to send in the following unless you would like us to leave everything loose when sending it back.
- 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. If we are installing a set screw type gas block, we will also dimple the barrel as part of this service.
We are now able to pin various gas blocks above the barrel (between the barrel and gas tube bores) using a smaller pin. This is the preferred method on certain blocks including offerings from Centurion and Badger Ordnance.
If we run into any issues with fitment like the block being too loose on the barrel, we will contact you beforehand to offer up a solution so we don’t pin on a block that will leak and cause cycling issues. As with every barrel modification service we offer, your barrel will be inspected for issues before any permanent modifications are made. An inspection sheet will be returned to you with your barrel with a record of everything that has been checked.
