Randy,
You could put one of CDNN's $799 LWRC M6A2 with Flip Sight uppers on your Colt lower.

$699 without sights
$799 with sights

$100 for a SET of LWRC's remarkable Skirmish Sights makes the $799 deal even better. I've paid $200 a set for them.

The M6A2 is a self regulated piston system with free floating quad rail and 20,000 round service life hammer forged barrel.

Sell your Colt upper for $350-$400 and have a M A S S I V E upgrade for $400-$450 net.
