I got a Colt Competition CRZ-16 back in December '16. It has a 10" hand guard that is likely not made by Bold Ideas, rather it is probably a UTG Pro or some no name rail. Crappy pics below warning:
the barrel nut flats are 1 1/4" , outside od 39mm, and length is 2".
My hope is that it is an available hand guard and I can buy a longer one and swap without pulling the barrel nut.
