If your goal was to keep your barrel hot for as long as possible, I'm sure you will be succesful. As far as answering someones elses question, that is NOT real parachute (550) cord. But yes your gun does look unique and cute. I imagine it won't last too long, or you will have a nylon snake following you around the range. Maybe you could pack some insulation under the handguard to keep the barrel even hotter next time you clean under the handguards.
