A gas-operated rifle balances gas port pressure against the sprung weight of the bolt carrier/buffer group. Using ammo with the wrong burning rate powder, or if your barrel's gas port is the wrong size will throw that balance out of whack. The result is failure to extract or failure to feed.

If your rifles cycles reliably with good ammo, you don't need an adjustable gas block.
