Barrel length and everything is your preference. I would suggest 1:7 twist.

Exactly my point. Be careful putting a SF on a DD, God may strike you down where you stand.

Well, just saw that Palmetto State no longer sells complete kits, minus the lower. You can still go there and piece one together, but the price for doing so pretty much runs neck and neck with Bravo Company.

It's like throwing a football from how I understand it. A good spiral helps it travel further and truer

From what I've seen, a 1:7 twist rate is 1 rotation every 7 inches in the barrel. A 1 to 9 rotation is one rotation ever 9 inches, and, since the bullet is slower, increases maximum range, but at the cost of some velocity. Same for 1:12 and such.

Yep it stabilizes the round. The ratio of twist differs based on the bullets diameter and length. A long skinny bullet needs more rotation to keep stabilized and a short fat round requires less. Too much rotation can also destabilize a bullet.
From what I've seen 1:7 is optimal for 5.56/.223
