If one were to be looking for a general purpose mil-spec type generic lower parts kit for an AR-15 lower receiver "just in case" and "for future reference"... who's got the best price and has currently available stock?
Theoretically speaking, re: AR 15 lower parts kits
These are my go to suppliers for AR-15 parts
AIM Surplus
Primary Arms
Palmetto State Armory
Plus a couple of others I check for sale prices
Schuyler Arms
Weapon Outfitters
Ive had good luck with the first three

Haven't used the latter ones. Palmetto has good stuff ant good prices but they are slow to ship in general.
I've used a few CMMG LPK's with good luck too. For complete kits, I've built several from Del-Ton with good luck. Good luck as in running for we over 1000 rounds of steel Cased ammo with zero Maintinence and still
Shooting sub MOA accuracy with decent ammo.
