At the risk of putting too many MOACKS options out there, here's the MOACKS Plain. All it does is stake the carrier key screws, in four places, in one setup. No scrapers, no clamps, no bells or whistles. As it is closed over the top, it can be smaller and lighter than the original MOACKS. You might say a downside of this is that you can't as easily do a visual lineup to locate the tool on the carrier. But the upside of this downside is that the Plain is made with two holes in the top-- just stick your 1/8 or 9/64 Allen wrench through the appropriate hole (depending on if your carrier key screws are the mil-spec 1/8 size or standard 9/64), and locate the tool to one or the other of the cap screw sockets.... now start stakin'. 1/8, 9/64, and 5/32 Allen wrenches are included. Screws and wrenches are from trusted American names in fasteners, tool body is made from pre-hard 4130 steel.
