Frequently Asked Questions: Does Faxon Offer Pinned Gas Blocks And What Are the Pin Specs?

Posted by

Yes and No. 

For our retail customers, Faxon currently only offers its own and various adjustable gas blocks. These blocks vary from set-screw style to clamp-on depending on the manufacturer. These gas blocks are not pinned and we apologize, we do not offer the option for Faxon to do at the factory for individual retail sale at this time. 

For customers interested in pinned gas blocks, please see our dealer AIM Surplus. We manufacture barrels in large volume for AIM which allows us to create the pinned gas block and barrel efficiently. AIM offers the vast majority of our SKUs in their inventory completed with a pinned gas block. AIM's pinned gas block is a hybrid design that uses the pin for location and set screws to help with gas seal. 

Details on the Pins Themselves

AIM Surplus gas blocks use a 3/32" x 3/8" roll pin where it pins to the barrel. This roll pin is included with the barrel. 

All Faxon gas blocks use a 5/64" x 5/16" roll pin for gas tube installation which is included with the gas tube.
