I have one. A bone stock LMT M4gery with a detachable carry handle. Several PMAGS and some aluminum GI mags.
You won't find much ARs with higher quality or attention to detail...yes, there are a couple of better ones out there, but for the price point, you won't find much that will touch it...
Very high quality components. Totally reliable. At most, I will add a sling, some kind of optics, maybe a suppressor, and maybe (maybe) a rail system.
The main dislike I have of the AR-15 platform is the loud sound signiture. I have seen unreliable ARs, but mine is rock solid and has only had 1 user caused issue that I quickly resolved...I'll happily take it to any carbine class and run it without fear of breakage (except I don't have the funds for the ammo).
