Seems to me that a large factor in having an accurate semi-auto gun is having consistent barrel harmonics. A semi-auto with a gas block mounted to the barrel would seem to disrupt the harmonics of the barrel.
Therefore, I have two questions.
Is the gas block on a very accurate semi-auto mounted at a vibrational nodal point of the rifle barrel?
Would "floating" the gas block around the barrel decrease variability in barrel harmonics and thus increase accuracy? I was thinking something like a semi-open chamber around the barrel that didn't touch it but still generated enough pressure to run the gas system. I think with this idea you could have a very accurate piston system rifle.
