I've got a 16'' pencil barrel from LaRue that I purchased a long time ago - 15 years? ago? I need a low profile gas block and a gas tube for it (believe it's a mid length just eyeballing it). No idea what gas block sizing for it, .750? |

The Larue pencil profile was the Predatar barrel. It uses a .625 gas block. https://www.opticsplanet.com/larue-tactical-predatar-m4-5-56mm-threaded-barrel.html?srsltid=AfmBOoqXYy0CW0VlW4vd8Io1qELWCxxZ7Q1CXlGM65FyQ6cv7JsE1blg |
