Building an AR, how likely am I to run into headspace issues throwing parts together? Like, fully assembled with bcg vs picking a different bcg, vs putting together an upper receiver, barrel, and bcg.

Googling and looking at fudd forums tells me that some people think that ARs are self-headspacing and that others think that building from individual parts is a recipe for disaster if you don't have a plan to set the headspace of your rifle.

What do y'all think?

Also, does anybody have experience with ar15discount.com's NBS brand? They claim all of their parts are just rebranded from trusted OEMs, but it seems like that's the case for PSA too. Kind of wondering how they compare.

Glad 8/k/ is back.

You're blinding me with all that glow, CIAnigger

Thanks. I may buy just the field gauge just to be sure but it's probably pretty unlikely given what I plan to buy for my bcg and barrel.

A stripped or complete lower receiver must be sent to an FFL and then transferred to you with an ATF 4473 form. Everything else can be mailed to you.
