'ello does anyone know if the AA uppers noted as "pinned" have a pinned flash hider making them "rifle " not NFA sbr? Also any feed back about AA upper and Wilson TTU?

My AA factory upper has a pinned gas block.  What barrel length are you referring to?  Most pinned and welded flash hider uppers are going to be 14.5" or 14.7" in length as the flash hider gets it out to the required 16"  Really long permanent flash hiders or fake suppressors are sometimes done on pistol caliber guns were ballistics can be affected by legal length barrels.  This would not apply to the AA upper.  A trigger is going to feel the same regardless of the upper.  5.45 and other Russian caliber uppers will need a trigger group with extra power springs to ignite the hard primers.  The TTU does not work well in this application.

thanks for input am thinking of 14.5 "pinned"  to 16  WA is non-SBR friendly (we do have about the easiest CWP in US)

Yup, that should be a pinned flash hider.  Usually the SBR/Pistol/PDW uppers will also say something like "ALL NFA RULES APPLY"
