Never used ADCO before but have always heard good things.  Not certain all the services I require.

I have a 16" upper I would like shortened to 14.5 or 14.7 with a permanent hider.  I can probably handle removing the barrel from the upper so I'd probably not need the disassembly fee.  I'm assuming I'll need the standard barrel threading.  What I don't know is if that's everything I want.

My barrel is the M4 profile, and looking at a 14.5 upper there is a small contour on the barrel just before the flash hider.  Would that be included in the barrel threading fee?  I'm thinking not because it would remove the finish.  Is my standard FH 1/2 x 28?

What were the typical services you guys used for shortening a barrel and permanently attaching??

If you want the lowered shoulder behind the pinned/welded FH, you will probably want :

Perm Attach Muzzle Devices Blind Pin: $30

Barrel Threading Standard Barrel Threading,1/2x28 : $65

Contour Barrel M4 .700 X .700 muzzle step : $60

Just one thing; forget '14.5" OR 14.7". If you want the standard A2 FH, and its already on the barrel, tell them to use it and make it 16" total. They are going to make their own measurements anyway since they are responsible for making it 16" legal. Okay, two things - I would pay them to put it back together. I do not have the tools to install a barrel. They do a great job and everything was tight and straight on mine. The new crown shot better than the Colt original crown. I believe the A2 FH with a slightly longer barrel is less noticeable than a 14.5" barrel with an obviously longer FH. The longer FH 'sticks out' more than the slightly longer barrel.

You would be better off buying a new 14.5 barrel, getting it pinned and selling your old barrel unless you are really attached to that specific barrel.

right, I believe the A2 FH with a slightly longer barrel is less noticeable than a 14.5" barrel with an obviously longer FH. The longer FH 'sticks out' more than the slightly longer barrel.http://goo.gl/0U2hFr

All good comments.

I'm tempted to keep the barrel and mod it.  It's a new Palmetto premium upper.  If I would have just waited longer to purchase I could have bought the upper I really wanted.  Was just tired of months of waiting for any upper to be in stock.
