[QUOTE="APDDSN0864, post: 2198608, member: 58226"] As a Colt Factory trained Armorer since the mid '90's, I can assure you that Colt has outsourced some parts of it's rifles since Day 1. Quite a few Ar-15 manufacturers that have been around for a while actually started as Colt subcontractors and still manufacture top quality parts for their own brand name and other AR-15 manufacturers. Not all current Colt AR-15 parts are made in-house, either. [I]ALL[/I] of the parts in a Colt AR-15 have to meet Mil-Spec, irrespective if it's a LE marked rifle or not. That is one of the things that Colt has prided itself on since the very beginning, and why they charge the premium. As to the caliber designation on the box vs. what the rifle is marked as, it's a marketing tool so as to NOT confuse first-time AR buyers as to which ammo to buy and use. The firearm markings prove that , in fact, it meets Mil-Spec for the 5.56 NATO cartridge. It will safely handle both 5.56 NATO and .223 Rem ammo. The real difference in a .223 Rem chamber and a 5.56 NATO chamber is the length of the neck/leade, with the 5.56 chamber having a longer neck/leade which allows using a longer bullet without running into sky-high pressure issues. The cartridges, both .223 and 5.56 NATO have the same physical dimensions, but the 5.56 NATO [I]is[/I] loaded to a higher pressure level. A few years back, it was not uncommon for unscrupulous dealers to get Colt AR-15's in, remove the Colt BCG, and replace it with an aftermarket BCG, sell the NIB AR-15 as a Genuine Colt, then sell the Colt BCG at a premium. Not all aftermarket BCG's are built to the same quality nor does every one undergo the same testing that Colt (per their .gov contract) does on each and every BCG. [USER=59526]@rustyshackleford[/USER], I went through my first recertification as a Factory Trained Colt Model O (1911A1/1991) Armorer just after Colt switched over to CNC machining and absolutely loved the parts interchangeability with vastly improved tolerances. The newer 1911A1/1991 pistols are consistently more accurate and last longer than the older ones. I'm with you, I hope that CZ will keep up with manufacturing technology while keeping that pistol as-is. Ed [/QUOTE]
