It must be ,I sent out my frame to have NEF fit a new barrel on July 22 the invoice was dated july 27 and ups brought it to my door today August 4th Thats just under two weeks from the day i shipped it. I called them last friday to see if they had received my frame and customer service said yes and that it was to be shipped back to me on the 1st or 2nd. Usually i get them back around 5 weeks from the day i send it. The new barrel fits like a glove keep up the good work NEF. Just wanted to share this with you guys later Tanoose
