A couple years ago I picked up a ND upper and lower in an attempt to support a local company. Then the following year I purchased a 16" 2 tone a barrel. So altogether running about $900 for everything. Fast forward to last month when I took it into a gunsmith to take down the assembled upper. Long story short, when the guy went to remove the muzzle device, the barrel pin broke. Not expecting much, I sent ND an email asking if they could help since they appeare to have good customer service. At the very least, I just wanted help getting the SilencerCo flash hider off. Then I could at least use the suppressor mount, gas block and gas tube for another build. I was told they could help me out with the muzzle device and they would sell me another barrel at a discount. So I made the hour drive to drop it off (Friday June 3rd) and was told they'd get to it on Monday and maybe help me replace it. No problem. A week later, I send an email asking for an update and the response just stated the barrel was ruined and my situition "sucks". I sent another email asking if they could at least just send me back what I dropped off and was told to call. I called, he said he was busy and would call me back. Basically blew me off. I send another email on July 3rd and have yet to get a response email or phone call. I don't really know what else to do. They have done nothing except waste my time. I always try to assume positive intent but at this point I have to just guess they are ignoring me. In the future I'm only sticking with name brands that treat ALL customers with respect. I wasn't expecting them to do anything big but now I'm out $225 on an upper, $435 on a barrel, and $130 on a suppressor mount, barrel nut, and gas assembly.
