Best lower for the money

Purchased two of these lowers while on sale. For the money it’s a no brainer. Best price for best quality. For the same money two other lowers come to mind, a psa lower and an Anderson lower. Out of the three stag is 100x better plus being made in the USA is such a plus! Fantastic warranty! If you are unsure what lower to buy look no further buy a stag.
