Thanks for all of the responses, especially using the Effin A along with the adjustable gas block. I don't think I want to drive myself that crazy.
I've decided on using a 14.5" barrel for easier mobility, with lite BCG (whenever I can find one from Young MFG).
Still deciding on the free float, but leaning towards the Apex Rifle Length. I like the idea of using a standard barrel nut.
Or more likely the Troy 11" Alpha Battle Rail (not the VTAC version)
I now understand not using a heavy buffer with low mas systems - thanks.
AR15BARRELS - I will be contacting you to pin my comp and barrel as soon as I'm able to order the parts.
