$389 for the Remington with a no name scope means you're buying a $385 rifle with a $4 scope stuck on it. So in reality that's just a $385 rifle.
$499 (let's be real and call that $500) for a Savage and a Nikon 3 x 9 is essentially a $385 rifle with a $115 scope on it.
Nikon made decent scopes for the money but Nikon is out of the scope business.
The Savage utilizes a barrel nut to attach the barrel to the receiver and set the headspace. That design allows for a significant reduction in assembly cost. The Savage also uses a bolt that is far less expensive to produce. As a result of the design, Savage can produce high quality rifles for less cost than their competitors.
The Remington 700 is an iconic American rifle but there's that entire bankruptcy thing. There was a time when you could buy a Remington 700 and be reasonably certain you were getting a quality rifle. Remington produced some good firearms in the last 20 years and I've seen several. However, that didn't mean they always produced good firearms. If you get a bad one, the only remedy will be to spend YOUR money to fix it.
SO, you could take a chance on the Remington and maybe get a good rifle for less than $400. If the rifle turns out to be decent, take the no-name scope off and toss it in the trash because it is just trash. Buy good rings, bases, a quality scope and call it a day. HOWEVER, that is contingent on the rifle being a good Remington 700 and there's NO guarantee that it will be a good rifle and NO remedy if it turns out to be a bad one. If you're adverse to taking risks, this will not be the path for you.
OR - you could spend a little more money up front and buy the Savage with a Nikon scope on it.
Nikon wasn't the top of the line when it came to rifle scopes but they were far better than the bottom of the barrel scopes. I had a 2 x 7 Nikon on a hunting rifle because I couldn't afford a lower power Leupold at the time. It was a perfectly serviceable scope that held a zero and never failed.
I stand by this statement - WHEN IT COMES TO OPTICS, YOU GET WHAT YOU PAY FOR.
