The Mannlicher M1893 is a semi automatic rifle chambered in the 8x50mm round. It uses a screw delayed blowback operation where the bolt has 70° angled locking lugs that have to overcome a quater twist that delays the action until the gas pressure drops to a safe level to eject. The bolt cocks the striker on opening (a la Mauser) and fires from a closed position. When firing the trigger pulls a lever connected to a sear to fire the weapon. The magazine is stripper fed and holds 5 rounds.
