Currently selling as Damaged

The gun will currently shoots at half its effective range and I can't fiqure out why. 

Some BBs will fly and others drop. 

Most likely needs a new hop up unit. 

I don't have time to repair so sadly selling. 

I got it from Swit airsoft so can grab a bargain if you can repair it. 

Comes with 5 mags and bayonet. 

Thanks.
