Stripping and assembling the MS M1900 bolt
      #292796 - 30/12/16 04:07 AM

I have been trying to find an article on the assembling of the M1900 Mannlicher–Schönauer rifle bolt but to no avail so thought it might be worth asking here.

To strip I de-cock the bolt, depress the safety flag and turn the cocking piece and the whole thing flies apart. More accurately described the bolt head disengages from the bolt body and the force of the firing pin spring causes everything to come apart somewhat unexpectedly first time. Now I understand the process re-assembly is easy enough, the ejector ends up on the left hand side of the bolt as it should be and everything functions as I would expect.

I will also add that the bolt head keys in as I would expect however the key is exactly where the bolt head is when de-cocked.

I have watched a video of a later MS bolt and that one did not fly apart as mine so is this a quirk of the M1900 or am I missing something?

No, you haven't done anything wrong. The same thing happened to me when I first disassembled a M1900 bolt. I too thought to be completely familiar with Mannlicher-Schoenauer disassembly. The M1900 was just one evolutionary step in the development of the "Mannlicher" turnbolt from Louis Schlegelmilch's M88 German commission rifle through the Mannlichers M 92, 93, 95 and 1900 to the fully developed M1903 and later bolts. On all the earlier bolts, M88 to M1900, the bolt head is free to slip out and in of the uncocked bolt. The M1900 merely changed the connection of firing pin to it's nut from the former full thread to the 90 degree interrupted one, as you know. The proper procedure to disassemble these earlier bolts : Uncock bolt. Slip out the bolthead with extractor and ejector. Push the firing pin tip down on a wood block. Press in the safety flag. Unscrew and remove firing pin nut. Slowly release pressure so firing pin and spring slip out of bolt and cocking piece.
The main improvement of the M1903 and all later Mannlicher –Schoenauers over the M1900 was cutting the notch for the bolt head retaining lug on the opposite side of the bolt body. Only now the bolt head is captive and needs a half turn to release it after removing firing pin nut, cocking piece and safety.

Thank you for confirming that Kuduae. I had not realised you de-cocked and then removed the bolt head first before further disassembly.

I do have a Gewehr88 amongst other things and keep meaning to take the bolt down on it as it has been ages since I did anything with it mostly because I have not got around to ordering a new barrel from LW yet
