We need "the chart". Lolz
If I might toss this out there: "The good Lord made men tall and he made men small, Col' Sam Colt...he made 'em all equal." ColtAmericanHeritagePoints++
If I ever buy an AR, it'll be a Colt. I'm just afraid of the hazing it'll get when it first goes into the gun safe with all the 70+ year old M1s.
Aero Precision has complete rifles too for about that same price, and I think Spike's Tactical do too
Even though Sam Colt had nothing to do with the AR?
I have three AR's. A pre buyout Bushmaster M4, a BCM midlength and a Colt 6920 and I think the fit and finish is better on the Bushmaster but when you take them apart for cleaning I think the Colt is built better. They all shoot great but if I could only keep one it would definitely be the Colt.
In all honestly probably 99% of all people will never put enough rounds through to wear out their primary AR or run it hard enough to even break it, so it really doesn't matter what the back-up rifle is. If your just wanting another AR to have another one on hand that's a valid point as most of us have more than one just for the simple fact we like owning them, building them, ect.
This is the best point to get across. Guys who don't have rifles that are already all scratched up don't & won't ever need a backup rifle. There's no shame in owning a range queen, or a collector showpiece, but people don't need backups to those, maybe a few spare parts at best. If you just want another rifle, then there's no problem with that either. If you want that next rifle to be quality and not an unreliable piece of steel and plastic that's good sense to want that too.
Truth of the matter is that if any of us ever needed a "backup" rifle it had better be in the hand of the guy right next to us when we need it most while we're transitioning to a side arm. I'll admit it and I hope I never need a backup rifle. I hope all I have are collectors & toys.
