You might also check Rainier Arms http://www.rainierarms.com/?page=sho...roduct_id=2239 their ultramatch barrels have a great reputation and I used a DPMS pattern one for my MA-TEN build I just completed. I have not fired it yet but the fit and finish is great.
I ended up with the fulton since rainier was out of stock at the time. Both seemed like great options.
