Lowest profile gb i could find - Lantac LA00243 .750 Gas Block Ultra Low Profile GB750-S .750" (7.62 Barrels) 41

In my latest build i had to switch out my Aero GB for something as short as possible to get my grip & Railscales to fit without having to grind down the mlok screws & bolts too much and thats when i came across this Lantac Ultra Low Profile GB. Its about 1/16" less in overall ht and about 1/8" less on front to back length and was just enough for my mlok nuts to clear underneath my Midwest industries 13" combat rail. Excellent Nitride finish and machining. This is the firsr gas block ive owned that the gas tube goes in the back and out the front about 1/8". Paired with Spikes Tactical Melonite gas tube and Balistic advantage 16" modern series barrel and everything went on smooth and the gas tube roll pin wasnt too bad with my FDC roll pin jig. This comes with set screws that have the best knurling ive seen yet, dug in without issue.
