Building an Air Rifle
« on: December 21, 2021, 07:29:24 AM »
Hi Bob,
I would like to find or purchase a drawing that shows the basics functions of an air rifle. Staying very simple, I would like to see the barrel, the breech, the bolt, and the method to get the compressed air to the pellet.
Can you point me in the right direction.

There are a lot of varieties, springers are very different than pumpers, CO2 or PCPs.... CO2 are probably the simplest, just a CO2 cartridge, a valve opened by the impact of a striker driven by a spring, released by a trigger.... The valve releases the CO2 which travels through a port to the barrel, which is closed on the back end by a bolt, so it drives the pellet out the front of the barrel.... A PCP uses compressed air in a reservoir instead of CO2, and you must have a method for filling it.... A pumper has an onboard pump to fill the valve.... A springer uses a spring and piston to compress air to fire the pellet....

There are lots of drawings on the Crosman website at:  https://support.crosman.com/hc/en-us/categories/200223634-Owner-s-Manuals-and-Parts-Diagrams

Thanks a lot Bob, I looked through the Crosman  site but I could not find any PCP rifles. PCP rifles are more interesting then the other types. I have a 4500psi compressor and a Hatson Hydra along with a umerx springer. I have owned and shot the big bore rifles in the past, but I had to sell them because my dogs would run and hide for a day or so every time I shop the rifles them. I wonder if any other manufacturers provide drawings of their rifles working parts?

I don't think you will find many detailed drawings for PCPs.... The manufacturers spend a lot of time and money on development, and aren't keen to give it all away.... You may find some help in the drawings and details of my 6mm project (a 2nd gun was .257 cal.)....

https://airgunguild.com/pcp-c02-and-helium-powered-airguns/any-interest-in-6mm/

The drawings are too small to be of any use to you, but there are lots of photos of the parts I made.... The 2 guns were later developed to shoot smaller slugs, .172 cal and .224 cal....

https://airgunguild.com/pcp-c02-and-helium-powered-airguns/smaller-caliber-pcp-varmint-rifles/

The end result was two PCPs, one regulated and one unregulated, both able to shoot all 4 calibers by swapping parts....  8)
