Is there a Colt lightweight with flat top upper?

[M2AP]

They are nice carbines. I did keep the Matech, at least for a while and mounted Micro H1.
I removed the original front sling swivel and installed a Colt side swivel.
Also I bought and installed a set of Colt Car handguards from SAW. They were a little salty, but they work better for the GF, and for me when wearing very heavy gloves in bitter cold weather.
And I also added a Magpul trigger guard.

A colt Middy with lightweight barrel would be the bees knees my friends, I would be all over that one. The 6720 is at least a step in the right direction. One can hope Colt expands their civilian market a bit more with a bigger selection of rifles.
