The single most important part of the rifle is nearly impossible to keep clean even in a garrison setting. The pinky never comes out clean and that should give us a clue. They have two or three lug bolts and they are the gold standard for accuracy.Īsk any soldier about weapons inspection and they will tell you the test is worming a pinky in the chamber of the rifle. Bolt-action sniper rifles don’t have star chambers. Some say the star chamber provides accuracy. That’s the eight-petaled flower at the front of the bolt. The star chamber and bolt face are perhaps the single biggest design flaw of the AR-15.That’s why gas rods have become all the rage. This is particularly common with AR’s that have shorter barrels. If a build up of mud, water or carbon decreases gas pressure to the bolt, the the AR-15 fails to cycle. The gas tube is thin, fragile and subject to bending or breaking-usually taking the rifle out of commission.That’s why in 2019 you can’t find a new AR-15 with an old school front sight assembly. This design flaw, right out of the gate, causes a huge mechanical offset where the eye lines up around three inches higher than the barrel. If the weight or spring compression in that assembly is off just a small amount, it causes malfunction. The front sight assembly sits ridiculously high because the straight (non-ergonomic) stock has to contain a massive spring and buffer assembly.The history of the AR-15 is a history of band-aids. In the military we are taught that the AR-15 is a fine weapon “as long as you maintain it.” In truth, the design works (80% of the time) in spite of itself, and has gone through so many design iterations that people have lost count. Any time you have a system that is complex, you have two results: efficiency and fragility. This sounds like an AA meeting for American veterans, so I better put up a decent argument soon before I’m lynched. My family comes from a manufacturing background. I’m a 28-year Green Beret veteran (8 years boots-on-the-ground just in Afghanistan).
