Things I liked: Very well built/machined. Solved the problem I had with the scope vibrating off the end of the gun due to recoil.
Things I would have changed: Upgrade the installation instructions adding more pictorial details.
What others should know: The scope mounting rings which came with my Gamo 890 do not hold the scope on the gun. So if you are pricing a new gun like this one factor in the cost of upgrading.
Things I liked: The gun is very well designed and built. The break barrel hinge is very strong as is everything else on the basic gun. The cheek rest is a nice feature. I added lock tight to the two screws which secure the placement of the rest after one fell out while I was shooting. The gun shoots accurately. I have my scope sighted in at 40 yards and am getting 1 inch groupings using a upgraded bipod and gun rest bags. I have to lean the gun against fixed objects while shooting in the standing position or I'm all over the place. Have put about 300 pellets through the gun.
Things I would have changed: Nothing
What others should know: I upgraded to a Leapers UTG 3-9x40 AO Rifle Scope and a UTG Low-Profile Dragon Claw Clamp-on Barrel Bipod. Also went with a Bkl 4" scope mount, bubble level and a Hawke Sport Optics Tactical Combo Kit. I am happy with the upgrades. Have found the new bipod through the gun's balance off when left on while shooting from the standing position. I use rubber electricians tape to protect the barrel from being scratched at the clamp on point.
