Windows Vista + trying to transfer pics via bluetooth = BAD
Moving on, I will try to show what pictures I managed to upload and explain the steps as best as possible. Sorry if they are all huge; I forgot to shrink them down before uploading them, and I have no wishes of wrestling with Photobucket to take some down and put others in their place.
That being said, Step One:

Cut off the turret along the visible seam. I reccommend a coping saw for this. After everything above the seam is gone, you may need to take a knife to what's left of the barrels to cut out the rest of the AR's.
Step Two:

Take your favorite Rose markers, pry off the backs with a good pocket knife, and empty those suckers out. The smaller part at the marker end should b e left on, as this will help you line up the new barrels.
Step Three:

Now take one of the caps from those Rose markers, and notch it like so. This will help it straddle the middle strut of the turret. Be sure to remove the middle part of the cap!
Step Four:

Take your notched cap and some epoxy putty, and glue down the middle of the turret. This will become the part where the removable barrels attach. I just eyeballed my centering job on it, which seems to work well enough.
DO NOT RESPOND YET, STEPS 5-8+ COMING WHEN I CAN GET THE PICTURES WORKING.
