Add to Warp's list the quality control procedures Colt uses on the LE's. Over the years Colt and the government have identified processes that contribute to the reliability of the guns. Mil-spec is more than material standards and dimensional tolerances, it's also an inspection and test plan that is designed to identify parts that could fail before it happens, and this stuff costs money. Each barrel fires a special high pressure round and is then put through Magnetic Particle Inspection to look for material flaws, and that's just one of the tests. The accuracy may not be on a level acceptable to a bench rest shooter, but that's not the intended function of the guns, it's having one that is as reliable as possible, one that will work when it's needed. Weapons that fail in combat can get people killed, and the LE series Colts are made to pretty much the same standards as M4's supplied to the military (barrel length and an extra setting on the safety differentiate them). Other companies do some or all of the testing required, some do it on representative samples, others don't do it at all. Compared to most other brands, for a rifle that may be used in a situation where your life depends on it, at present price levels, the Colts are tremendous bargains IMO. If you have other intended uses, then the Colt may not be the best option.
