AA 16" barrel handguard question

[sqeezeatrigger]

Is anyone using the Diamondhead VRS-T handguard ? I have one on a 22 upper and like it more than any other I have seen or handled but on a 22 there isn't any clearance issue. I'm wondering what would be the best gas block- any low profile in particular? I am patiently waiting on barrel and bolt from AA and want to get all my parts lined up. Thanks

Measure your inside diameter. Look at the specs for various gas blocks. Most of the manufacturers sites will have the dimensions.
