For reference of just how easy this is, most AR-15s that I’ve seen have been units built from individual parts, my own included. That’s kinda the AR-15’s whole schtick, is that it’s super modular and customizable, so much that a lotta people joke that it’s “LEGOs for adults.” It makes good sense, if company A makes a good upper, but Company B makes good triggers, so why not mix and match for the best of both worlds?
