A friend of mine recently bought an MP5 online and sawed off the orange tip before inspecting the weapon for shipping damage, thus voiding any and all warranty. He found a problem with the stock: It's collapsible... when you don't want it to be. Instead of holding at a specific notch, the stock just slides whenever there's pressure on it, regardless of whether the adjustment lever is pulled.
I took a look at it, disassembled the stock assembly, and found the problem. A round piece attached to the inside of the adjustment lever that (at one point) had two nubs that slide into notches in the stock's arms when the lever is released, and out of the notches when the lever is pulled. On an otherwise all-metal MP5, this piece which should be able to hold more than the gun's weight was plastic, and the metal arms of the stock had apparently snapped the nubs off of the piece, rendering it useless.
I haven't yet found much in the way of replacement parts, and I don't want to advise my friend to spend another $80 on a stock with most of the same parts he already has. This isn't an $80 fix, it's just a little piece. Does anyone know where I could find an individual replacement part such as this?
