Specifications
United Defense Labs. .750 Adjustable Gas Block
The Gas Block on your AR-15 / AR-10 style rifle is an integral part of the gas system that allows your rifle to cycle. By tapping off gas from the barrel and diverting it back into the gas key of the bolt carrier group, there is enough inertial force to unlock the bolt carrier, send it rearward to the recoil assembly, and extract and pickup another cartridge to fire.
About this Gas Block:
This gas block is machined with a .750 Gas Port. .750 Gas Ports are standard for AR-15 barrels chambered in .223 Remington, 5.56 NATO, and .300 Blackout. This gas block size is known for its reliability it assisting the rifle function in regular and adverse conditions. This gas block has a 'low-profile' design and is made to fit underneath a free-float handguard. The gas block adjusting screw is located on the opposite side of this gas block. When needing to adjust the gas block, the handguard will need to be taken off. After roughly 200-500 rounds are shot through the gas block the locking screw with solidify and remain in place.
Gas Port Size:
This gas block is an average .750 size gas block.
Platform:
This gas block will work on both AR-15 and AR-10 barrels, for .308 and 6.5 Creedmoor barrels, be mindful of possible tolerance issues in the barrel profile.
Adjustable:
This Gas Block is adjustable, allowing the user to tune how much gas is needed, this is useful for testing different ammunition, running suppressors, or other adverse conditions that you may need to tune your gas settings with.
Profile:
This Gas Block is 'low-profile' and designed to fit underneath freefloat handguards.
Finish:
Nitride - This gas block uses a nitride finish, making it have improved rust and corrosion resistance. Nitrided parts are typically glossy in texture.
Attachment Style:
Slide On - This gas block has a fixed size, and must slide on from the front of the rifle and is secured in place with 2 set screws near the bottom.
Material:
Steel - This gas block is made from hardened & tempered steel, providing the strength and rigidity to withstand forces of expanding gasses and vibration from the rifle or pistol under operation.
DISCLAIMER: **Before purchasing, please be mindful of possible tolerance differences resulting from your handguard profile, barrel profile, gas length, and barrel gas port.**

Kinda sorta works
The screw to adjust the gas bottomed out and the bolt would still catch meaning I couldn't fine tune it. It bottomed out and the gas port was about half closed. It functions and there is less recoil but I would liked to have been able to choke it down and get just enough to make it cycle with as little recoil as possible. Running on a 350 legend so it might be a little more gassed up than a 223. Fit is good, install was quick, would be great it adjuster went deeper.
