What would you guys say is the "best" lower parts kit out there right now. I don't need absolute top of the line, but I was less then impressed with my DPMS. I was hoping for somewhat better quality...not much, but just enough to make it noticeable. I don't like how the bolt catch wobbles, or the safety feels kinda funny when using it. Or am I pretty much stuck with that no matter what? Also curious as to whether you can get a LPK with a better trigger anywhere. I didn't see any on the major retailer sites. Wouldn't mind hearing what everyone's favorite single stage trigger is as well for a service rifle.
