CMMG has a good selection of Mil Spec Barrels in 1-7. Crome Lined, M4 Profile, Very Good Guarantee. You can get a Barrel, or a Barreled T Marked Flat Top Upper, with or without Bolt & Carrier. Jeff also spends some time on this site. The CMMG folks are also into using the equipment they sell, and promoting it's use through competition, not just taking your money for a product they sell.
I have talked with Jeff on the phone, and through several E-Mails, and he is extremely helpful on answering your questions. I have been looking at quite a bit of equipment lately working on 3 seperate M4 projects. CMMG and LMT would be my first two choices on barrels, with Colt on the list if you could find a Colt 16" barrel for $275 - $300, which I consider to be the maximum I would give for a barrel made by anyone. I saw a listing on Colt barrels earlier in the week for $500, that is totally insane. The Government gives less than $600 for the complete rifle. Take a look at the products made here in Missouri by CMMG. www.cmmginc.com CMMG also has some other AR16/M16 items for sale, all are top quality.
