Lo-Pro Gas Block with Expert Design

Most modern AR-15 builds need a quality low profile gas block to ride under a free-float rail.  Fortis’ low-pro gas block does the job with style, featuring facets cut into the sides, a bevel to reinforce the front, and an engraved Fortis logo to top it off.  This gas block rides under most free-float rails today, but it’s ideal match for a Fortis Night Rail or Rev 2 M-LOK Handguard.

Available in black nitride or stainless steel finish.  Includes 2 set screws and 1 gas tube roll pin.  Pick up the gas tube you need for your build here!
