The kit comes with all the parts you will need to install the repeater breech kit as well as convert the bolt to a cock on opening mechanism. Basic hand tools are required for installation and the install takes about 30 mins from start to finish. Instructions are included for the install, but you can also watch out install video below. With the QB 78 repeater kit you'll maximize the shooting capabilities and fun of your Beeman QB 78.

also comes with one magazine clip but I ordered 4 more get about 55 to 65 shots before its down low on co2.This was my qb78deluxe 177 now I'm going to do my 22 next.
The magazine feeds the pellets smoothly into the chamber with each of the four pellets I have tried so far. All of them were domes from Crosman, JSB, H&N and Air Arms. Two of these group into less than 1/2" and two of them into a little over 3/4". I am very pleased with the smooth feeding and very good accuracy. All pellets also shoot almost identical points of impact with 1/2" variation in elevation only.
The instructions were very clear and will guide you into just what is needed to complete the installation. I have converted two QB-78 rifles using the performance upgrade, and both rifles gained over 100 fps from the factory velocity. This Repeater upgrade has all of the same improvements of the performance upgrade with the addition of the receiver, barrel and other parts needed.
With the very good pricing of the QB-78, this upgrade allows you to have one heck of a nice looking rifle that is both accurate and powerful for a little under $300.00 + the cost of the optic of your choice.
