From the trailer we see that Rey had a blue lightsaber. Which to me looks like the Skywalker lightsaber.

That means that she either repaired the lightsaber or made a new one and modeled it after the Skywalker lightsaber. But personally I think that the Skywalker lightsaber is almost like a beloved character. One that shouldn't die.
Second Rey also has a blaster which is very interesting, because Jedi do not use blasters. Actually to my knowledge, neither do the Sith. I have actually thought that Rey would never become a true Jedi in the sense that she would never go by the old codes that we see in the prequels. Forbidden attachments would never work for her as that is the only thing she has ever wanted. It is also the most ridiculous rule that the Jedi have. I have said this many times in conversations on wattpad, but I will say it again. Love (real love) is the most good and pure thing in existence, anyone who is against love is evil. That includes the Jedi (Sorry) The Jedi claim to be selfless, but can you truly be selfless if you have never loved someone else more than you love yourself?
Sorry, I was getting off topic. But the fact that she has a blaster proves that she will not become a Jedi, at least not the kind of Jedi we have seen so far. Perhaps she becomes a new type of Jedi or Force user.
Back to the blaster...

I seen a lot of people say that this is the blaster that Han gave her.
So, I decided to look at picture (mostly because at one time I thought this might have been Han's actual blaster.)

But now that I look at the picture, I'm pretty sure it's the one that he gave her.

I think that this is really cool. As this scene is shown Luke says: "a thousand generations live in you now."
She is literally holding Han's legacy, Anakin's legacy, and Luke's legacy in her hands....
