I had alloy parts from them last week so I can assure you they do!
The hop ups are listed in with the sapres, just search for the part numbers you want.
To be honest all I personally use is the alloy rear hubs UMW516-0 and the rear hinge pin mounts LAW36 and LAW37.
I've just done a quick search on their site against the part numbers (look in the SP/FS/RB5SP manuals and you will find them all) and all the bits appear. Looks like I might have just ordered the last LAW36 but I bet that fresh stock will be there today or tomorrow.
Best option if your not sure is to ring or e-mail and they will be more than happy to help, Ryan and Stu can never do enough and are always up for a bit of banter whilst they are at it
