Trying to change the barrel on my R25 and can get the handguard threaded piece off. Please see video


Sometimes some heat from a torch helps.I could be wrong BUT... If the tubular HG came off and it was threaded on OVER what looks like a barrel nut (lots of holes in the front one of which the gas tube goes through), then that's the barrel nut. You will need a multi-prong barrel wrench.
Those barrel nuts are aluminum and can be a real bitch to get off.
This is what I used on AR10's like the DPMS...
