Working on a build, some parts scrounged but new. Using a rifle length FF tube that I won at a shoot, packaged as Hogue with a car stock and grip. Got the barrel and decided to see how it looked. That's when I noticed the gas tube holes a normal armorers wrench engage are recessed about 7/16". No way my armorers wrench will get ahold of those! Does anyone make a wrench that will do this? I really don't wanna strap wrench this match barrel on, it just seems silly. I'll try to get pics in a bit.
