Anyone here have experience with a Superlative Arms adjustable gas block on a LR-308? Just installed mine, and hope to be headed to the range on Tuesday. One suggestion is to start with the gas block closed and open until bolt locks back, the other method suggests starting with it wide open. I've been told that most/many LR-308s are overgassed and I'm trying to reduce the number of attempts here, and was thinking of starting mid-point which is two turns to reduce the trial and error here. It's not like this is a big deal, just looking for any tidbits or experience here.
