Why is a terminal emulator checking their account anyway? Who puts DRM on a terminal emulator besides Microsoft?

Unless that guy is a Smurf in whiteface, that is definitely more than 26". It’s probably a 16" barrel, the minimum to not be a SBR. It might be more like a 12" barrel, making it an SBR. It looks like most AR-15s are ~19" plus the barrel, so probably ~35" overall length once you include the suppressor. That’s a screw-on stock, so it’s technically removable, but so is everything else.
