I want to go with a 14.5" barrel. Should I have the existing barrel cut (2008 Colt 6920) or buy a SOCOM barrel I can get for $250 probably less (it's a new in the wrapper that belongs to a friend, he never mounted it). Thanks. I know, 1.5" is negligable but it's just something I want to do. He also has a Kineti Tech http://www.kineti-tech.com/kineti-te...leeve-2-piece/ he'll include. Thought I'd get the brake permanently mounted if I do this.
