Gas tube doesn't fit.
The barrel size is correct but my gas tube is to big to fit into the hole on this gas block. I have a .556 ar-15. Other than that it seems fine

Looks and functions great
Small enough to fit the free float guard around it and looks and functions great. Comes with a new pin to install, nice when building from scratch or you loose or damage the old pin.

No Different from Blocks that Cost 3X as Much
This gas block fits and functions fine, and costs about 13 dollars. I was worried when I ordered it, but not after installing it on a new 223 build. It works great.

Will this operate a 7.62x39?
Answer:
If your AR barrel measures 0.750" in diameter at the gas block, then this will work.
Will it fit Ruger 556?
Answer:
This is compatible with the Ruger AR556 barrel, but depending on your current setup, this may interfere with some free float handguards.
Is it high profile ?
Answer:
No this one is standard height. Try item # ARR-631-101.
