Fun Project URX 3/3.1 " Aluminum " Add On Rail Panels... custom machined and Moly Resin Coated
I recently got in a KAC URX 3/3.1 Rail accessory deluxe kit just for the rails.
What I found is that there is no way for the older KAC rail panels to lock on which is a need for my current build. In addition to that the KAC rails are plastic. I didnt like that so I printed them and made some for myself out of 6061-T6 Aluminum.
These will last allot longer than the KAC Factory URX 3/3.1 plastic rails.
Heres a factory plastic add on rail panel
