If you can't afford $20 then why are you building a gun instead of paying your bills?
Jesus some of you people are just whiny window lickers
Who said I couldn't afford it? But it's still a cost to be factored in, ESPECIALLY since the OP is trying to build a budget gun & presumably ordering only 1. When I order SN'd lowers I order 4-5 at a time cause the FFL I order from charges $20/box (up to 10 SN's) that way It averages out to $4-$5 per lower. Also I have mainly ordered SN'd lowers from Joe Bob's & any orders over $90 are free S&H so I don't have to pay that either. Until a year ago I didn't have to pay tax either which I would locally. Ended up saving a lot of money like that. Saving money, means more money for more builds, ammo, or whatever.
