It fits inside the shot tube assembly, where it aligns with the barrel. Notice the long air tube that projects from the front of the black piston seal on the right. A spring anchor in the gun holds the back of the spring steady when the cocking lever withdraws the piston and compresses the spring. Spring & piston assembly: The mainspring is held captive by the piston assembly. The combination of these two forces works like the booster rockets in a space vehicle only in this instance, the boost means that the mainspring can be made light enough for younger folks to cock, yet still supply adequate power to launch a BB.
As you now can see, it relies on both a catapult action and a spring piston to do its job. That's the cycle of the BB gun powerplant. For the rest of this discussion, please refer to the illustrations as you read. 25 pump BB gun, will work just as well with this powerplant. The one we will examine uses gravity to feed the BBs, though other types, such as a spring-powered forced-feed magazine found in a Daisy model No. The BB gun powerplant is a hybrid of both the spring-piston and the catapult designs. Because I have a modern mechanism to examine, I will report on just that but if you take the time to look at the older models, you'll see a lot of their design has been carried forward. We'll call it a Red Ryder, and it may well be, but the mechanism is common to more than just a single model. But not always! I discovered a few years ago that very few real airgunners are aware of just how a BB gun powerplant really works, so I thought I'd take the time to illustrate it.ĭaisy helped me with this project by sending the shot tube and spring mechanism for one of their modern lever-action airguns. Veteran airgunners are used to this reaction from the public, but when they get with other enthusiasts the conversation becomes deeper and more precise. Show an airgun of almost any type to someone who doesn't know airguns, and they'll call it a BB gun.
