Basically would take under 30 minutes to take off the flash hider and handguard (2 bolts) check gas block and check barrel torque specs. If even 1/2 hour. Hell Id be willing to do it for you! My bet is that the barrel nut is over torqued. Regardless of the money spent you owe it to the gun to check it out.
