When you take the Macro line off the reg you'll notice the inside of the macro fitting has a hex shape , find the hex key that fits, turn the end cap off. Now look at the side of the reg where you adjust the velocity. Turn that hex screw out completely. Now the regs internals are ready to come out. Make sure to keep the shims in order. The 05 speed manual is available on line for proper shim placement. Now you'll notice another screw, this one mounts the reg to the main body. Undo that one and your now done removing the reg from your gun. If the reg is loose before doing all the above, a leak is prolly present huh?? Tighten the screw on the inside of the reg after applying a dab of grease to the gasket Inbetween the body and reg.
For all your angel repair needs
