Those are good choices. However there are many more good choices.
Good budget AR choices are: S&W, CMMG, Windham weapontry.
Better choice is a colt 6920. Walmart has the magpul edition ones for $1080. If GM will price match that, I'd to it over anything else unless you want to spend a little more. See below.
For the money and quality you can get these top tier rifles: BCM, Daniel Defense, LMT standard patrol, etc..
For more money you can get: Larue, Noveske, LMT piston, etc.
Checking the online website, it looks like you can get the colt 6920... That's where I'd put my money. If for some reason you ever sell it, you'll get as much as you paid for it.
1911: Colt, Springfield armory, dan wesson, les baer are all known to be great 1911s.
STI is a good choice too, but they don't have the history of the above.
There are a few others, but the best choice for the money would be a Colt 70 or 80 series, or a Springfield operator IMHO.
