Bolt-action sniper rifles donвЂ™t have star chambers. Some say the star chamber provides accuracy. ThatвЂ™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.

ThatвЂ™s why gas rods have become all the rage. This is particularly common with ARвЂ™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.ThatвЂ™s why in 2019 you canвЂ™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 вЂњas long as you maintain it.вЂќ 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 IвЂ™m lynched. My family comes from a manufacturing background.

IвЂ™m a 28-year Green Beret veteran (8 years boots-on-the-ground just in Afghanistan).
