At a premium price I'd expect it to be a tack-driver. Did you strip and clean (the gun) before first use? A lightweight 308 carbine can be expected to be a "jumpy little thing" and just figuring out how to hold it steady while pulling the trigger can be a challenge. They look very well engineered and made--I've bought a few of those tactical buttstocks your rifle has for my AR builds and do not like them, IMO delicate and move too much for my tastes. In general you want a tight AR with as little play in the components as possible.
