The standard gas system of the AR-15 platform poses a problem when installing handguards or rail system that extend past the barrel's gas port. If you're looking to install a long handguard or a rail system and need a low-profile replacement for the factory gas block, Fortis Manufacturing has the answer.

The Fortis Low-Profile Gas Block is machined from rugged 4140 steel to provide the enduring reliability that customers expect from Fortis. The block is short enough to accommodate a handguard of any length you choose. It is fixed to the barrel with two set screws, so you don't have to be concerned about scuffing and scraping your barrel during installation! The slick, streamlined design is an interesting break from the ordinary as well.

The Fortis .750 Low Profile Gas Block comes in: Black and Stainless Steel finish.

  • Aggressive Looking Gas Block

    Posted by Christian Juncaj on 13th Oct 2020

    This part caught my eye the most when I was looking for a gas block. I was more impressed in person when I recieved it. Pictures can only show so much. It was tricky getting the pin and gas tube to align, but I managed to assemble. Performs pretty well when I went to the range.
    Great product Fortis and thanks for supplying Wing Tactical!

    For less than 75$ this is a great looking LPGB. It isn't adjustable but it does the job on most mid length and and carbine length barrels.

  • Stylish

    Posted by Gary B on 3rd Aug 2015

    Well stylish is not really what gun people primarily look for, it does have a place a little lower on the totem pole of priorities, but it is still on the Totem Pole. Form and function are great and the matte stainless steel color is different. I want my rifle to function and shoot well, if it can look good too okay!

    FORTIS makes excellent quality items. This is my second one. The stainless is matte and blends will with any type of barrel. IMHO. :)=
