Just received my new QB 78 D in .22 cal. today.
Worked the last hour cleaning it all up,boy was the barrel full of brown lube of some sort, but I finally got it all cleaned out.
Waxed the stock all down and coated all metal parts with RIG.
Good looking rifle, nothing like the Chinese pellet rifles of 20 years ago.
Will know in the next few days how it shoots.
Claims to get 50 to 60 shots from 2 Co2 cartridges.
