Any low profile gas block that will accommodate the 1.340" insdide diameter of the handguard will be fine as long as it matches the gas seat diameter of your barrel. It your gas seat is .750" diameter the following Fortis model should work:

Fortis has one on there website, But any low profile gas block will work. Fortis makes great products but there is a lot
who make nice gas blocks. Just have to get the correct size for your barrel and proper gas tube length for what you are building. Most likely your barrel will have a .750 size but the pencil barrels are .650. and get correct length of gas tube.
And recommend having a gunsmith do it if you have never done it. Some barrels like Noveske come with gas block pinned
from there shop. They cost a little but top notch. Good luck with your build.
