AR adjustable gas blocks

[Porter]

The only ARs(PWS/LWRC) I own that have AGBs are also piston driven. I use them solely with supressors, all my other DI ARs don't have one installed nor will they be used with a supressor. Piston ARs are great with supressors because they run clean as an AK. I am also notorious for not cleaning my rifles enough so that's a major plus for me.
