New Question: On 5.56 barrel selection, Should I go with 1:7 or 1:9 Twist? Chrome lined or Non Chrome lined? Want a 16" w/ mid length gas system.

I would say check out the dealer area:

Dealers/Ranges Forum


Remsport comes to mind, good guy and he is some what close to you.

Good luck...

New question posted on 1st post. Guru's work your magic! So many choices, it gets a little confusing

Twist rate depends on projectile weight you plan on feeding it. If you're not sure, go with 1:8 twist. There's enough documentation available (google search) to give you the full run-down on the differences. Basically, heavier projectiles work better in tighter twist. Lighter ones tend to break up if you twist them faster (so 55 grain in a 1:7 twist will be bad). I believe the 1:8 will give you the best of both worlds.

As for chrome lined or not, I believe it's more personal preference. I'd opt for stainless if I had the choice.
