You can buy lot’s of gun related stuff on Amazon, from stocks and sights to lasers and holster. Well now you can buy 80% AR-15 lower receivers directly on Amazon. There’s nothing illegal about selling and buying 80% lowers on sites like Amazon as these aren’t considered firearms. These oil filter suppressor adapters however, they probably shouldn’t be sold on Amazon. Sold by Palmetto State Defense (not to be confused with Palmetto State Armory), they’re made out of forged 7075-T6 alunimum, tumbled and de-burred with mil-spec cuts.
Check them out over on Amazon.com here. Amazon needs to start selling ammo already, then my Prime account will really be worth it!
