You just opened a big can of worms. Colt fans will tell theirs and the same with Bushmaster. We shoot colts at work, and I was in the same delima. I went with a Bushmaster. The price is right, the quality is high. No doubt colt is the same,but they are concentrated on the military.I am not a big Colt fan. I have never had a problem with my Bushy. Research it and make a choice. The Colt will always have a higher resale because of a name. My opinion is that you have the same freakin product,one with a older name and longer history but both offer quality products. My biased answer would be the Bushmaster, look at the online catalog and support they offer. Unbiased answer would be to research both weapons, both are good. Find a dealer or shop that isn't biased and offers both and compare the two.
