Just got the news that Dan Young has started a web site (for all of us who don't do facebook). It's Welcome to Young Manufacturing | High-Quality AR-15 and M-16 Firearms Parts and Accessories
. Don't overlook the .net , not .com! They have very high quality parts for the ARs. I just got a super fine chromed bolt and carrier group from them. Prices are very, very reasonable too, especially for the quality. Check it out!
