I own two AK's, an SKS (Soviet not Chinese), an M1 Garand, a National Match M14, two AR's etc., I've had more stoppages with the SKS. This proves nothing. "Shooting a lot is relative", the mean stoppage rate in the Army tests was one stoppage per 166.66, 30 round magazines, as I stated earlier. How often do you burn through this many rounds in a day? I've been shooting the M16/M4 family since 1977 when I went to boot camp. I served 8 years, nine months and a few days in the Marine Corps. All of that time but about a year and a half in an Infantry Company. I then did four more in the US Army as a Special Forces Medic (18D). I spent a lot of time deployed and in the field. I have a couple of AR's that I have shot regularly since then. I never remember a stoppage problem at the range, it was virtually non existent. More so in the field or when deployed, but then it was still extremely rare. Civilian AR's vary widely in their quality, some brands are more prone to malfunctioning. I don't know that I've ever had a stoppage with my personal AR's. My life has depended on my rifle and I was perfectly comfortable with the much maligned M16 series. I've had two son's in the Marine Corps, one did eight years, the other four. One went to Iraq and Africa, the other Afghanistan. One was actually involved in one of the ACR evaluations, both rate CAR's so they weren't Fobbits. Neither has ever mentioned any problems with the M16/M4 series rifle. In fact both own AR's.
