In the context of this thread, the gas blocks are at the end of the handguards, there would be no long wrenches. Further, it's strange you're suddenly opposed to an adjustment due to the proximity of the muzzle while simultaneously OK with mounting and unmounting a silencer between strings of fire. The general public is stupid, they point guns at themselves without adjustable gas systems. Next time you're at the range look at the ceiling and count the holes.
How much gas adjusting are the proponents of the RS gas block doing on a routine basis? I asked the question earlier and the only response was from the OP and basically said he don't know. There's a recent video about the RS from the dude sometimes affiliated with TFB, his use case appears to be he is shooting random 308Win ammo all the time for video purposes.
