Perfect.
Mounted easily and works as it should.
USI needed a low profile gas block and AR15discounts had one with the gas tube insalled!
I had been upgrading several AR's and with the AR15discounts slim handguard I needed a low profile gas block and noticed they had the block with the gas tube already installed for a few bucks more so when I got my order everything just slid into place.
