Why hate china?
Speaking of china, the Type 63 is an interesting example of the weird stuff china pulled off with dated equipment. Similar to how the US during WW1 had a lack of M1911 to issue to troops, they hired both Smith and Wesson and Colt to manufacture a .45ACP fed, easy to produce handgun for use by officers and MG teams, this caused the M1917 to be born.
Based on their larger framed civilian revolvers, the M1917 is a moon clip fed .45ACP revolver.
Now back to the Chinese, did you know the Type 63 is not an SKS? Despite it's outward appearance, it looks like simply and SKS with an AKM magazine, but it is in fact a mash of the two. Removing the SKS tilting bolt and replacing it with the rotating bolt system that their Type 56 (AK47 Type 3 licensed copy) that was fielded in 1956, the issue of fielding this new rifle was the lack of them available. It was a new design with new factories and tooling. The lack of fieldable Type 56s was a major issue, the requirement to have a full auto capable, yet long range capable rifle led to issues of just defaulting back to the old SKS.
The Type 63, which started it's development in 1959 entered service in 1968, which at that point (even when it was in development) made it very out dated. None the less, the Chinese, and the PLA used them, the PLA calling them the Type 68 after their adoption year, and the Chinese the Type 63 for their development end year.
Type 63s use a cut down 20-round "proprietary" magazine, firing the 7.62x39 round. The 30-round magazines had to have further modifications done to them to make them fit and fire one of the major ones was removing their Last Round Bolt Hold Open. The rotation bolt system allowed for this easy use of AK47 magazines, as well as allowing it to use (modified) AK parts. They were quickly used up and sold off to various countries, a few examples had their auto sears welded and were exported to countries like Australia for civilian sale, thankfully with the know-how they are easily reconverted to select fire.
