"For an entry level Sniper this gun is decent. I had some issues in the beginning when shooting the gun the bbs wouldn't go super far then just drop straight down. I adjusted the hop-up and tried various weights off bbs until this gun started to shoot correctly. Now it shoots decently far and fairly accurate. The bottom rail attachment for a Bi-pod broke off on me. It's only screwed on with 2 small screws. I wish they we're bigger screws to keep it more secure. Oh, well. Some gorilla glue should do the job. I also had an issue with the bolt being jammed and not going back all the way. I had to open the gun and take the trigger mechanism apart. A small piece became loose and I put it back together and now my sniper shoots again. It's possible that dropping the sniper caused that small piece to move and start jamming the gun. The adjustable cheek rest doesn't stay put very well. When I rest my face on it, it starts to move and not stay in place. I bought this gun on sale for 79$ and I still think its worth it. However if your looking for something better quality go with something more expensive. It'll save you headaches in the future.
