I bought a Remington 700 PSS with a whole "sniper package" a couple years ago. I then parted all of the accessories out, and by the time I was done my PSS was a $125 rifle.
I did the same with a tricked out AR-15, sold the light, scope, quad rail, and put a regular trigger in and sold the 2 stage trigger, and when I was done with that one the rifle was about $220.
I think a lot of people either don't have the cash or just get nervous when they see a $1600 price tag on a package deal, but usually when you add up the used value of all the accessories you can get a pretty good deal on the gun if you are willing to take the effort to sell off the extra stuff.
