New build, failure to extract spent shell, charging handle hard to pull back

[Bigs28]

Headed to range today with adjustment screw on block out 1 turn. Same issue. Took another turn out of screw and same issue.

First do you have the detent model gas block or the adjustment screw with locking set screw?

When you say you backed it out 1 turn, did you mean a full 360 or just 1 click of the detent? Straight from jp on using detent model.

2. Back the adjustment screw out one full rotation (six clicks). Load a single round into the
magazine, chamber it, and fire. If the bolt doesn’t open at all, open it another four clicks and
try again. Most likely, the bolt will short stroke at this setting. If that is the case, clear the
rifle before proceeding.

I feel you are not opening it enough and still undergassed.
