Faxon Adjustable .625in Low-Profile Gas Block, 3-Screw

The Faxon Adjustable Low-Profile Gas Block is a three-screw, .625-inch gas block designed for AR-15 platforms. Its adjustable screw placement limits contact with gas port carbon to reduce fouling and seizing. Constructed for repeated adjustment, it supports fine-tuning of gas flow for both suppressed and unsuppressed use. The block is intended as a direct-fit low-profile solution for builders and technicians who need precise gas regulation.
