Today we uncovered a problem with the King Arms M4 transparent model that we believed, you as the paying customer deserves to be made aware of. The trigger contacts in the rifle are not the best in the world.... However don't let this be off putting to go ahead and purchase this rifle. It is an easy fix!
The contacts in the King Arms are open to corroding relatively quickly, even with a small 9v battery connected. However, today we opened up an M4 that was having issues firing on full auto. This was due to a slightly miss shaped trigger contact. The problem was simply resolved by replacing this contact with a brand spanking new Dboys for £15.99.
To prevent the contacts from burning out we are also now able to fit our home made MOSFET in store before posting for an additional £20.00. The MOSFET works by lowering the voltage going to the trigger contacts from 9v to 1v yet still delivering full power to the motor. Below are a few photos of our in store engineer investigating the problem along with a picture of home made MOSFET fitted into the M4 front.
