Fortis MFG has recently released a new low profile gas block for the AR15 platform. These are made from 4010 steel, are parkerized, and attach with two included set screws. There are two models, with one being designed for a pinned installation, and the other dedicated to set screw installation. Both of the Fortis LPGBs are sized for the standard .750 barrels, and are priced at $55. Fortis MFG has also included the gas tube roll pin.
