they are very small, and there is alot of plastic, but they shoot close to 495, and there pretty arrurate, but i wouldn't get it if your a grown person, they are small, like a toy gun.
My cousin has a Gamo Spectra (they don't make em anymore, but it looks to be the same as the Delta), and as Chops says it has a lot of plastic, and on his Spectra the barrel is synthetic but it is rifled. Stock cracks relatively easy.
dont buy it!!!! i got it and i thought it would be awsome, and i didnt listen to anyone. it doesnt feel very good when you hold it, its to light, and its a hollow stock, i just hate it! DONT GETTTT IT!!!!!!!!!!!!!!!!!!!!!!!
my airguns, Crosman Quest 500, Gamo Delta, Daisy Buck, and Diana Mod 24!
