Better than NEA!
For 20 bucks cheaper than your standard NEA LPK, this one is just as good, if not better. Parts finishing is a bit better as the anodizing is nice and black. Parts match and fit perfectly on my standard NEA lower. ||Would be nice if the grip screw was a hex rather than a flathead, but no big deal!

Awesome Kit
Put mine in last week, everything fit well. I installed the parts into a Norinco lower and it functioning flawlessly.||The TNA LPK is nicer than the Norinco ones by a large amount too. Very happy with mine.

Easy install except for Bolt Catch
All parts installed easily except for the bolt catch. I was able to install it but it is rubbing on the slot of the Aero Precision lower. Adding some oil and working it by hand has loosened it and I expect it will just get better with time.
