look at this video of a DD5V1 fail. The person dropped it on the ground and the 4 bolts that attach the free floated handguard shifted and caused the rail to be out of alignment with reciever. There were other problems as well. Good thing I did not buy this rifle. also this rifle had issues with trigger failing to reset. Think I will stick to Windham's, Colts, and believe it or not I love my Sport ii. I would be definitely be bummed out had I spent 3K on a rifle and then find out it had many issues. I am also thankful I was here kicking this question around and pondering before making a rash decision. I understand the vast majority of DD owners are not going to drop their DD on the ground, but you don't see ven rifles like Bushmaster or DPMS doing this stuff.
