Parallax Fixed Top Rail

Pretty simple replacement, but it does make assembly a tiny bit more difficult. This uses a SINGLE PIECE SLIDE. That means you need a printer that fits it, or to just figure out some other slide combo for it. The single big slide is what gives you an extra 10-32 bolt to use from the original hardware kit. Screw one of the 10-32, 2-1/2" bolts into the top rail (or don't, it will be a little weaker). 📷 Image redacted — claim this model to add your own media Mostly assemble the rest as normal, just drop the slide down and slide it forwards and into place. Ta-da, fixed position top rail so you don't lose your dot when priming.
