Thinking of getting a Armalite upper for my RRA lower. Any problems?

[thebaron]

I'm thinking of picking up an Armalite upper to stick on my RRA pistol lower. Anyone see any problems that might arise? How is the color match?

What about using the charging handle/bolt from the RRA pistol upper in the Armalite upper? Any foreseeable problems with that?

Thanks!

I have a Armalite upper on a Bushmaster lower no problems so far color is black and match's just fine
