that's like, your opinion
concur on using right tools for the job, but that 22 liter ultrasonic tank probably isnt ideal for field cleaning.... :upsidedown:Until someone takes a DI and a piston to the range, fires the same number of rounds through both at the same pace and measures the temperature of the bolts immediately after they lock back after the last round I am skeptical that the temperature difference will be that great.
I have a 22 liter ultrasonic tank. A 16" upper will fit diagonally in the tank. Not a problem to get it clean with it. Just gotta use the right tools for the job.
in any event i have both pistons and DI, id be comfortable using both...
