There are a lot of cheap lower parts kits on the market that are being made overseas. You won't know unless the "manufacturer" says they are made in the US.
Wholesale price on some of these Taiwanese LPK's is under $20.
They are anything but Mil-spec. Hardly any of the US LPK's are Mil-spec, and I learned that the hard way in the Arctic with a look-alike gun.
The TDP and Mil-spec calls for most of the parts to be MPI'd to ensure your bolt catch, hammer, trigger, selector, and disconnector don't have micro fractures in them.
The Mil-spec detents are supposed to be cadmium plated, whereas the detents on the market are almost always zinc-plated, which invites corrosion.
We're seeing more and more hammer and trigger pins breaking, disconnectors that aren't timed right for the LPK/lower receiver combo, spring sources all over the map, but hammers and triggers have appeared to get better from the porous DPMS units that were common a few years ago.
One of the really nice LPK's that you don't hear a lot about is the J&T/Doublestar kit. You often hear the DD recommended, and they are squared away. A lot of the retailers get them from different vendors at different times, so you can't really say, get brand x, because brand x isn't really a brand most of the time.
