What is the VLTOR WEAPON SYSTEMS - AR-15 Gas Block Low Profile .750 Steel Black?

Slim replacement for cumbersome USGI front sight/gas block tower features a low profile for a more streamlined appearance and less chance of snagging on vegetation and other gear. Covers only 1" of barrel length and reduces weapon’s forward weight for improved handling and maneuverability. Clamp On models squeeze around the barrel with included socket head screws. Set Screw models use included set screws at the bottom of the unit to anchor the gas block to the barrel for the lowest-profile installation.

Fits like a glove
I installed this gas block on a 0.75 inch diameter Black Hole weaponry barrel. It fit nice and snug. The gas tube hole was nice and snug as well. After tightening I attempted to whack the gas block with a mallet to see if it would move. It did not. Now after 300 hot experimental hand-loads there is NO gas leakage. This gas block fit under a Midwest Industries SS type extended hand-guard without touching.

Super nice fit on Black Hole Weap bbl
I installed this VLTOR low profile, side clamping, gas block on a standard profile, stainless, 24 inch long, 6.8mm SPC, Black Hole Weaponry barrel. The fit was nice and snug even before I tightened the bolts. It stayed aligned while tightening. I then fit a rifle length gas tube and covered the whole set-up with a Midwest Ind. SS, 15 inch free floating hand-guard. This gas block fit underneath just fine. It fired and cycled from round one and I now have 300 rounds through the rifle without a single problem. No leaks of any gas. Alex Clark Homer, Alaska

Great Low-Pro Steel Gas Block
I used this on a 16" Mid-Length Gas System AA 6.5 Grendel barrel. I have fired it in both extreme heat at 100 degrees F, down to 18 degrees F with never a malfunction using various loads. This is one of the best steel low-pro gas blocks on the market. The gas tube does fit tightly, which is a good thing for a reliable gas circuit. Loc-tite is your friend when tightening the screws after testing that you have a proper gas circuit. Read the limitations as to what handguards it will not fit under. The finish and logo are features that go above what other manufacturers offer on most of these types of products, which shows that VLTOR goes further in making a great part. Every VLTOR product I have used so far shows a higher attention to workmanship, finish, and functionality.
