Greetings all.

Searched to no avail.

Are these 13s actually 13.5s in disguise?

Pics appear to show a fair gap on 14.5 barrels, unlike the newer rails actually marked 13.5. Though, those actually might be slightly long.

Anybody have an installed length on marked 13s?

Geissele 13" is 13" and the newer 13.5" is 13.5".
