I am about to order one. It's 40.00. It looks like it needs adjusted. Are any preadjustes so I don't waste expensive ammo trying to dial it in?

I
think the McCann plug comes with 4 or 5 replaceable jets that you switch out, so it's easier to go between different loads once you figure out what works best.
The Schuster plug is more infinitely adjustable. You start with it closed (the rifle won't cycle) then open it up a little at a time until the rifle cycles reliably. It shouldn't take more than 5-7 rounds, I would think.
The Garand Gear plug is the newest one out there. It is not adjustable, but is "hollowed-out" to increase the volume of the gas tube and lower pressure on the op-rod. It sounds very intriguing, and most reports so far are good, but being a newer product/concept, some folks are still skeptical.
