Need help to identify an AR hand guard

[88Mustang]

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.

Colt Competition wasn't a Colt endeavor, you probably know that. As I understand Bold Ideas went belly up, but cannot confirm that. It DOES look like a Bold Ideas rail, though.

Thanks for the info, I didn't realize they made rails

I ended up ordering a BCM 15" KMR ALPHA KeyMod Free Float Handguard with index-less barrel nut on sale at primaryarms.com. The existing handguard will be posted in BST/parts and accessories in near future for those interested.
