Ummm, no. A relay requires time to energize the coil, time that coupled with the spool-up of the gearbox to fire means that you have increased lag. People who use a FET use it to help redce lag. Plus, a relay costs about as much as a trigger switch, especially if you use a quality relay like a Bosch, and it requires energy to close the switch, and does not eliminate arc formation. It moves the arc from the switch to the relay.
A relay will also take up room, room that most guns simply do not have in abundance. A Bosch-style relay is about 1" x 1" x 2", a complete waste of space, especially in an AUG.
A FET is not the best answer either, as it has reliability issues, and is susceptable to the inductive spike generated by the motor. But it's a better option than a relay.
