A device that allows you to compensate for bullet drop

I haven't talked to her in a while, I should drop her a line to see how she's doing.

a brake compensator aka proportioning valve.do to the fact that the front brakes useually do 70 percent of the stopping the compensator reduces the pressure of the brake fluid from the master cylinder to the rear brakes being they need less hydraulic pressure to stop. it also acts as a saftey valve in case a brake hose or line bursts, it will let to brakes retain pressure for emergency stop

A compensator for looks only. Air soft "weapons" don't generate enough recoil for one to be needed.

The voltage drop in a line can be decreased by
