adjustable gas

The Edge comes with an adjustable block and my Saint Vic has just a low profile gas block, can i put an adjustable on her and if so would be called a low profile adjustable gas block? And I am having trouble finding out the hole size, apparently there are 2 or 3 common sizes if i understand...

Hey everyone, I recently purchased a 300 Blackout Saint Victor with a 9 inch barrel which came with the adjustable metering screw. I was wondering if anyone had issues with the screw backing out or vibrating loose? Is it necessary to upgrade to a different gas block? I am planning on running it...
