I have the crossmen pulse R71 repeater just got it today and haveing some problems with it.?

Ya, that gun isn't so great. My friend got it for me for xmas, and the bbs didn't come out of the barrel in full auto. Dude, the gun just sucks! return it and get a cheap co2 pistol, or if you have the budget, get the r76! (the r76 is really just an ak 47/74 that shoots hard!)
