Just for some reference, as I've found and seen, all of these rods used, abused and freely swapped around, even mis-identified as well. Simply due to the relationship of all of these weapons, I figured it should be pointed out, because sometimes it's not quite as easy as this takes this exact rod, that takes that exact rod.
Chinese Ak47 is 15 5/8 inches.... 15 & 1/2 to 15 & 3/4 inches is fairly standard for all other Combloc AKM & Ak47
Russian Mosin M44/Chinese Type 53 17 1/2 inches (Chinese Type 53 Mosin rod is usually "not" knurled on the end, also most commercial made rods are also smooth on the end)
Same length rod is found/used in the Polish, Hungarian and Romanian M44 variants.(These will typically have knurled ends, ones with numbers like a Hungarian rod could be stamped 02/Romanian rods will have the Cugir arrow stamp/Polish no bluing or in general, any M44 rod with knurling could be a collector item)
It kind of makes sense, both the M44 and SKS share more than most think, I mentioned the relationship of all of these weapons, lets take the cartridge, magazine and action design out of the equation, you then have two weapons with barrels the same length, the same exact bore diameter, both have attached bayonets, even the overall weight and length is so very close. In size and weight, I mean close enough to give or take an ounce or two and maybe about a half inch or so in length. So why make 2 separate rods? I bet if Russia had put a trapdoor in the Mosin butt stock, it would have shared the same cleaning kit.
For special case scenarios...
Mosin M91/30 is 26 1/4 inches. This rod could easily be utilized to solve a "lack of rod" by cutting and rethreading with a 5/32" - 32 die(it's close enough to pass visual muster and usually will fit the cleaning kit accessory’s in a dire emergency, 99% of collectors don't use it anyway, it's for looks and appearance only) if desired due to fairly common commercial availability.
The Russian, Chinese, all Mosin Nagants, Euro/Russian AK's, SKS(Chinese,Russian,Romanian,Albanian) all share the same cleaning rod threads. Only thing I could find different, the Yugoslavian SKS & AK firearms are said to have used a slightly different thread pattern, standard Combloc/Chinese Mosin/Ak/SKS M3.5 x 0.6 vs. Yugoslavian M4.0mm x 0.7, Thread pitch from a Soviet armory repair manual shows 4.06mm x 32TPI, or a 5/32" - 32 die which is close enough for gov't work...
At a show, if one is at wits end, out of patience, hunting a generic rod for a SKS with the faintest of thought of cutting and threading,
Avoid the following....
You find a mile long cleaning rod, it could be for a Russian/Finnish Mosin M91, these are 29 inches long------>
Special warning<------ Do not cut, for it's collective value, you could probably easily trade 2, maybe 3 or more normal SKS cleaning rods for it depending on what you find, the ends will be knurled in various ways, slotted, pinned and brazed/welded on.
Same applies to what one would think a regular old junkie 24 3/8 inch rod is, these could fit Finnish M27, M28, M28/30, M39 Mosins, M27RV is 21 3/8 inches, again, value could be worth x number of standard SKS rods, again, the ends could vary, being knurled, machined, slotted, pinned or even brazed on.
