(5 out of 5) Original Colt AR15
by Thomas from Los Angeles, CA on July 29, 2016

What a great deal, a real Colt without all the add ons for a discount price. If Hillary gets in these will go up to $1800. Buy them while you can

(5 out of 5) Colt M4 under 600
by Jason from Chesapeake, Virginia on February 7, 2017

I was shocked to see this under 600. I have so many already, but no Colts, but I wanted it!!!
