Okay, this time I'm gonna ask the questions BEFORE I start screwing things up.  Sometime in the next several days, I'm going to install a RAS style float tube on my Model 1.  It currently has a standard carbine length float tube.  

After I get the front sight tower off and remove the gas tube, I'm gonna guess that the float tube is 2 pieces...the barrel nut part, and the actual tube part that must screw over the barrel nut part?  (I'm assuming it's gotta work like the Hogue, even though I can't budge it by hand.)

If I have in fact guessed correctly, can I get the front part of the tube off with a strap wrench?  The armorer's wrench has the 2 pins on the back side that fit the tube barrel nut, so I quess once I get that far, I just have to get the barrel nut loose).

Does this all sound right?  Thanks again...I promise this'll be my last question tonight hehehe.  

Sounds about right...just be careful with that gas tube and roll pins...lol.
