I'm looking to build an SBR.

What will I be limited to firing ammunition wise from an 11.5" 1:9 twist out to 100 yards or so?

How about 50?

What yardage and MOA combinations can I expect from XM193 and M855?

Does anyone have a link to a table?

Also tag since my next purchase may be a 11.5" Bushy with a 5" FH that can be removed after the paperwork is approved.

MOA is barrel & ammunition dependant - not length depanant.

Upper is advertised as a "Double Star 11.5" upper 1:9 twist"

Does Double Star make their own barrels? They are the ones with the eagle/falcon looking bird on their lowers, right?
