Actually I do not know. I just got it a few days ago and haven't had time to look through it yet. Overall it's an amazing marker and you can pick them up for not too much used. They are definetly worth the money.
Yeah, I've had mine for a while, so when I got it, it was only a few $$ more than the 7 was. I actually prefer the milling on the 7, but wanted the lighter weight of the Rapper.
Yep, my setup is pretty heavy especially with that 88 cubic inch tank. I will probably get a 68 cubic inch tank soon to drop some weight and make the gun more comfortable to shoot.
