Hi everyone I am an AR newb. I just recently bought a new RRA 9mm AR. I am trying to remove the buffer tube and install a new milspec buffer tube on it so I can put a collapsible stock on the thing. I removed the buffer and spring no problem but I can`t get the pistol buffer tube to unthread. Is there a trick to this or am I just not putting enough force on it to unthread it from the lower.
