sounds to me like you want a totally different gun. the 6920 is a basic ar 15 that is overpriced IMO. its got the colt name on it and little else, comes with milspec parts etc. 10 years ago it may of had something. now days there are so many cheaper guns that offer more and are just as reliable. I would get a RRA. even though all I do are customs that are pieced together from the parts I select. I have a RRA carbine that IS NOT going anywhere nor will it be touched beyond new furniture etc. shoots just about everything you can feed it decent and to the same relative POI. a buddy ordered the same thing his gun sat unfired for a few years last fall we took it out and got it dialed in. same story shoots just as good.
