[QUOTE="Seattlefungus, post: 910640, member: 76677"] Any name brand AR will appreciate in value if cared for. With the current state of high quality CNC machining. I personally have not seen a new upper or lower out of spec. Olympic, CMMG early production pieces were rough, I build thirty plus custom AR's a year, Tactical Carbine, 3 gun and Service Rifle. But for at least the last five or so years their quality is solid. The only negative I've ever had with DPMS was their practice of using the Teflon coating on some of their receivers. They look good until scratched and nothing short of a total refinish will ever make a match. With Mil Spec Anodizing there are a number of chemical reaction treatments that will blacken the aluminum for minor blems. On Twist rate, 1/9 sounds like the right rate for 300 and under with standard Mil Spec M193 55g ammo or other cheaper available ammo, right up to good match grade 69s. About the piston Sigs. Not any of the piston military rifles take anywhere near the medals at Perry as the AR15 direct impingement system. The lack of rifle movement, due to the shifting mass of weight keeps the AR groups tighter. And I've seen shooters try using the Sig in local cross the course matches against ARs. AR shooters out shoot them. Could be the 4 less inches in barrel or just skill level. [/QUOTE]
