o.k
I never used one of these before. All 3 of my 15's had 6-pos collapsible tubes
I pick up a Standard Rifle tube and of course the locking nut....
Obviously, the locking nut is only needed for the M4 adj. tubes. I can see that now that it is in my hands.....
So what keeps the standard rifle tube in place?? I just crank it in hand tight?
I know this is a seriously lame question.....but I haven't seen one of these yet......
