Product Description
The Fire Button and 2 Adjustment Buttons (Up/Down) are joined together with a 1 millimetre sprue, that will need to be trimmed away before installing. There will need to be a bit of trimming on the back of the buttons and in particular the fire button will need trimmed down to at least 0.5 millimetre so a thin disc is left due to the tight clearance with the onboard fire button
