[QUOTE="parshal, post: 1347834, member: 605"] I've used mostly Bartlein barrels for my builds but did chamber two Proof carbon barrels for lightweight carry builds. Yes, you can get a similar weight steel barrel but hanging a 14 oz. suppressor off the end certainly changes things. The carbon barrel gives me the weight savings and mass. The Proof carbons proved to be shooters so I chambered a few more of their steel barrels. For me, the Proof barrels have been smoother to machine than the Bartleins. As Bigngreen says, the runout on the lathe of a Proof is zero in my experience. All the Bartleins I've tested between centers have .004 - .007" runout but they all were still shooters. If Proof pays that much attention to runout then what else are they paying attention to? [/QUOTE]
