Airsoft bbs curve to the right. Help!

Question

My air soft gun is an echo 1 m4a1. I shot a clip at a target and the bullets seem to curve a little to the right.I used.20 gram bbs and there was no wind blowing. Can someone please explain to me how I can fix this and how I can get the bbs to shoot a little left?

Answer 1

Is the hop up adjusted properly?  If yes, then try a heavier BB.  

Also, if you just lubed it the gun may shoot wonky for a little while until all the excess silicone lube is ejected out of the barrel.

If none of the above there could be an issue with the hop up alignment.  Take it back to where you got it for an exchange.
