I thought the NSN model was calibrated for the M4's 14.5" barrel. But the Trijicon website says it's calibrated for 16".

Which model is for the 16" barrels anyway?

Trijicon had the eye relief values for the TA31 and TA11 reversed for about 2 years on their website, so I'd take it with a grain of salt. Considering the TA01NSN was developed to meet the military requirements for SOPMOD and SOPMOD features the M4 carbine with a 14.5" barrel, I would guess that it is a 14.5" barrel and not a 16". Ballistically, there isn't a lot of difference between the two though. It is less than the width of a crosshair at 600m.
