I bought a new LW V7 back in November. Ive had several little minor gripes with it, although nothing major or catastrophic. My stock trigger was absolutely horrible. It felt like an employee picked up a handful of sand/dirt, dumped it in the lower receiver, and then shipped it out. I tried putting 100 rounds through it to "break it in", although it hadn't changed at all. Give it another 1000 rounds and maybe it will. I ended up putting in a CMMG trigger group I had in another rifle into the DD. That other rifle is more of a suppressor host, so it doesn't see a lot of use, nor am I concerned with total accuracy in that rifle. The stock CMMG trigger is leaps and bounds better than the factory DD trigger. It could very well be that I just got a bad trigger. Maybe my parts are all at the outer end of tolerances, creating the horrible feel. Whatever the problem, its a very poor feeling trigger. Its something I would expect from a "lower tier" manufacturer; certainly not from a top name brand manufacturer.
I also have an issue with the stock grip replacement. That issue is well documented in this section, and is not limited in its scope to just my rifle. Multiple other owners have reported the same issue.
I bought and paid more for a Daniel Defense based on the notion that its a "top tier manufacturer." In my own experience now, I wont buy another DD rifle. I paid a premium for things that shouldn't be an issue.
These are my opinions only, and based on my one lone DD rifle. As such, your experience may vary.
