Where is a good place to send my AR-10 upper to have a new handguard and barrel installed? I want something like a Troy handguard, and a good match barrel no longer than 18".
I think most barrel makers will do this. I know Krieger will, and send you back a completed upper, with it chambered, gas block installed, etc. You need to send them your handguard and other parts.
See www.kriegerbarrels.com, and click on the AR-10 selection to the right. They respond to e-mails pretty fast as well.
