By "other color" I assume you are referring to Ghillie Green.
Ghillie Green has a swirl pattern to it:

The only pieces of the Hogue AR15 Kit BFG Grip Rail Forend Accessory that will fit your chassis is the pistol grip and the buttstock. However, to fit the buttsock, you will need to have a fixed adapter for an AR15 buffer tube to fit the buttstock. The rail will not fit.
Yes, this should have no problems fitting any barrel.
This forend unfortunately does not have rail cuts in the handguard. There are attachable picatinny rails that screw onto the handguard.
The free-float forend is rifle-length.
Mark H,
Unfortunately, Hogue does not list that specification.
