Hey guys. My recently purchased SIG 516 upper has a bayonet lug machined into the gas block. I want to keep it as aesthetically pleasing as possible, and therefore want to remove as little as possible, yet be compliant. Please advise which of my below options would likely be deemed acceptable.
I don't know anything about Baltimore Harbor; but yes; currents really can be that strong.
A big cargo ship like that isn't very maneuverable.
Most of the shipboard systems and controls are electric. If the lights go out, they have big, big trouble.
