I heard about a training outfit who is teaching a different way to change a magazine in an AR. Supposedly (I say that because I wasn't in the class) one school is teaching a different way to replace a magazine: drop the empty mag, unlatch the bolt, insert the new mag, and then rack the slide and cycle the bolt. This is done because the trainer says you cannot trust the bolt to strip a round out of the magazine from the locked open position. Has anyone actually seen this specific technique being demonstrated? Has anyone seen an AR actually fail to properly feed from just pressing the catch on a new mag? It seems to me that if it happened very often, more schools would be demonstrating this technique. I suspect this school is just trying to do things a different way so they can be unique and say they are pushing the envelope..... so to speak. It's not the way I was taught, and it doesn't make a lot of sense to me. What say you? If you have seen it demonstrated, please don't mention the school by name.
