I'm starting a build and I'm confused about LR-308 adjustable gas blocks - in looking at Midway's offerings, I see a lot of adjustable gas blocks labeled as being for AR-15. Is there any difference between a .750 gas block for .308 and one for .223? I could imagine that a gas block intended for .308 might have a larger inlet hole than one for an AR, to allow a greater amount of gas to move the larger & heavier BCG. Is that not true? If not, then I would assume any quality .750 adjustable gas block would work on the LR-308 platform. True? thanks
