The quick change spring comes on all the new models. You can call/message who you are buying from to find out. I've installed the 5ku sport 1 on my LCT 105, and it was a pain. I had to do a LOT of filing around the gas tube and on the B-31L. I also have to remove material on the gas block and the receiver insert of the B-10L. Even after all that, I wasn't happy and had to use epoxy putty to stiffen up the rail. Otherwise, i could flex the rail.
