I have the original Blue Label Box (with the label in perfect condition) for an AR-15 Colt Lightweight Sporter Rifle model 6530. It is for rifle serial No. SL003731. This box adds a value of $100 or more to your rifle.
If you have this rifle the box is yours (but you pay the shipping). Just email me proof of the rifle and it's yours.

PS: I also have the box for a Colt SSA Serial No. SA18548
