Can some in the know offer some suggestions on quality brands that don't break the bank? I'm building an AR-15, looking for a 16" barrel. I'm thinking 1/8 twist but that's still up for discussion at this point, I shoot 55gr bullets pretty much exclusively. Brands I was looking at so far. Rock River (I've seen plenty of examples that shoot great so the barrel must be good is my reasoning) Daniel Defense (read good things about them on here) Spikes Tactical BCM Anything others I should be looking into?
