Anyone tell you the weird "MINDEN" marking on the right side of the mag well? Nobody seems to know what it means from what I have seen. I believe it only appears on Canadian civilian ones. There are however several states in the US with a town by that name as well as one in Germany. There are also different left side receiver markings per version and what country the rifle is exported to and whether or not it's a civilian or select fire version. Ones in the middle east as of late turn up with no markings what so ever. It should be pointed out that Iran makes it (whether by Norinco license, laughably because it's an unlicensed clone, even though I believe the patent for the design is now dead but wasn't at the time of the 311's first appearance, or unlicensed I don't know) and again same situation with Sudan. They make it same specs, same furniture, but Iran seems to make theirs in a sort of rip off of US digital camo pattern paint jobs. Iran's special forces and police only seem to use them now though as they have the Khyber 2000 (I think that's what it's called) which is actually a bullpup redesign of the 311. The 311 was actually supplied by the Chinese to Mujahadeen and similar groups in the Russian Afghan war in small numbers where it was reportedly disliked for reliability issues (which I'm sure wasn't the gun necessarily so much as the fact they used their guns to death and probably didn't clean or maintain them regularly, look at the beat up guns they find today and back then) and they tend to scoff at .223, Norinco M14s were also supplied. Interestingly enough, I have heard fake US markings were put in the Norinco guns because it wasn't any secret we were arming and helping the anti-Soviet resistance groups at the time and China figured it'd be an easier way to deny anything if openly brought up politically. (China and Russia have been in tension for decades despite communism.) Several third world countries who have made their own AR-15 variants locally have actually used the 311 as a basis instead of regular AR-15 designs, keeping metric dimensions. I find it funny that Sudan used to use the AR-10 (one of the few countries who actually did, and made it locally under license) and nowadays use a local copy of the 311 (metric differences, unlicensed, Chinese instead of US or licensed production of reputable company.) I mean they are a third-world country, but the fact they went from first world standards to third world (though I'm sure cheaper,) standards is interesting, historically and politically speaking. I'm sure it had to do with the AR-10 being bought and paid for by either colonial or post-colonial aid and because it's similar and they probably no longer get aid and aren't a colony any more, they just went to the cheapest modern option.
