Now I know better than to think you are going to change anyone's mind about anything. Factual information, tests and subjective review usually play very little part in someones opinion. We all have our ideas about the way things are. One common gun belief (especially by those who favor the AK family of weapons) is that the AR platform in unreliable. There is no doubt that there was problems with the gun when it was introduced into military service but most of these problems where because of dumb decisions made outside the control of those using the firearm. There where some real problems, mostly because it was rushed into service without testing or proving the system. That was 40 years ago though and those problems simply dont exist in today's world. I am reading this AR book by Patrick Sweeney where he sets out to test some AR's to failure. He starts off doing pretty much what you would expect. He throws dirt in them, dunks them in a barrel full of water, mixes oil and sand and pounds it in the places that matter seeing if he can get a malfunction. He does this to a total of 8 rifles, some piston some DI, and with the normal tests he is not able to produce any malfunctions. He then pours water on them and stuffs them in a snow bank to freeze. Melts snow in the receiver and lets it freeze, pours sand and snow in the receivers with extra oil. All the rifles function. So then he throws the rifles off a 20 foot tall roof repeatedly, He drives over them in a gravel lot with three vehicles including a Ford F-250. He throws them repeatedly as far as he can. He then shoots a entire box of 12 ga bird shot at each rifle. He makes a serious attempt to say the least. None of the guns fail to fire. One the flash hider explodes due to being packed with mud, several have broken external bits. One is seriously bent and has a broken take down pin. However they all fire. Another good example is the "Filthy 14" rifle. The following is a recount of its life "We received the carbine in late 2008 and put #14 into service shortly thereafter. At Brady, Texas, in March 2009, it suffered a malfunction, which was reduced with Immediate Action. The bolt was wiped down at 6,450 rounds. At Prairie du Chien, Wisconsin, in May 2009, it had several failures to extract, and the extractor spring was replaced at 13,010 rounds. This is far beyond the normal extractor spring life under these conditions. At Wamego, Kansas, in June 2009, two bolt lugs broke at 16,400 rounds. We replaced the BCG. Considering the firing schedule, this is within normal parameters. At Columbus, Ohio, in November 2009, we had several failures to extract at 24,450 rounds. The shooter gave it a field cleaning and replaced the extractor and extractor spring. At 28,905 rounds, we finally cleaned Filthy 14. As part of our year-end maintenance schedule, we inspect and replace parts as necessary. Filthy 14 looked like the inside of the crankcase of Uncle Ed’s ’49 Packard. It was disgusting to look at and contaminated everything near it, somewhat like the toner cartridges for old printers." The rifle is still going strong at over 40,000 rounds, Still not being more than field cleaned when it malfunctions. At 40,000 rounds its still never had its bore or chamber scrubbed. My personal feeling is that if you have a solid correctly built AR, its a pretty reliable thing. There are lots of unreliable AR's but I think that is because people buy a pile of parts and throw it together with no understanding of how it all needs to work together. Just because a pile of parts bolts together does not make it a rifle. Would you expect to take apart 5 Winchester 94's, throw all the parts in a box and then randomly use the parts to build 5 "new" rifles and have them all work without adjustment? Thats exactly what people expect out of a AR and most of the time they do Anyway I am interested in any real world AR stories you have good or bad. Id especially like to hear from vets who carried M16/M4's and real experiences. Where your guns the fabled "jam-o-matics"?
