I recently disassembled mine to refinish the stock. The disassembly/re-assembly is pretty straight-forward, except I wanted to remove the spring clip on the bottom of the handguard. It's held in place by a circular nut with two holes, similar to the cross-bolt retaining nut found on Mausers and Mosins, only much smaller. None of my snap-ring pliers would fit, so a friend of mine who owns a machine shop fabricated a tool from a flat blade screwdriver.
No matter how big and tough you are, when a two-year-old hands you a toy phone you'll answer it.
