Sick of using normal selector to decorate your RBR PTW?
Why not try our HAO's RBR style selectors?
Full CNC machined from Alloy 6061 which is strong enough to face any combat situation
 
Installation instruction for infinity version :
See last picture of BD NITE version.
Slide gear 1. off the selector. Take off the cover 3.
Fix the gear 1. with screw 2.(Don't forget the busing ) onto your Infinity gearbox.
Put the cover 3. back onto the gear body. Bowl shape side up.
Slide the 4. selector back onto the gear body. Screw in the hex screw in the selector against the 3. cover to secure the selector onto the gear body. 
Done!
