PLEASE TAKE THE TIME TO READ:
Due to the potential of serious injury, Airgun Development, Pedro Giesbrecht will in no way be held liabable should injury or death occur from anyone attempting to build or make their own pneumatic rifle or any type of airgun from information presented on this website. High pressures are used and poor judgement in machining or design practices will cause serious injury. I am a professional toolmaker but still an amatuer at building rifles. Please heed this CAUTION!
i) Velocity - I am a resident of Canada. Therefore I adhere to the laws governing airguns and build my airguns to meet the requirements as such. I use a shooting chrony to ensure I stay under the 500fps (feet per second) law. I in no way encourage anyone to build any type of airgun that will exceed these limits, nor will I provide information allowing others to increase the velocity above the legal limit. Each country has its own laws regarding the power, velocity of an air rifle. Please learn and abide by the laws in your own country.
From my understanding of the Firearms Act and the Criminal Code is that each defines an airgun differently. When an airgun is used in a crime, velocity and power are combined changing the classification. Please contact Canada Firearms Centre for more information or a lawyer to clarify. For more information on the laws governing airguns in Canada visit the link below.
ii) Word of Caution - Precharge Pneumatic (PCP) rifles use very high-pressure compressed air. Building a reservoir tank that fails to meet three times the used pressure (3000 psi - 9000 psi safety, 1/3 ratio) could result in serious injury or death.
Again, Airgundevelopment, Pedro Giesbrecht, will not be held liable for any injury or death resulting from information used in this website to construct any part of an air rifle. The information presented on this website is for your own personal knowledge only.
NEVER USE OXYGEN to fill any reservoir!
Oxygen mixed with any oils will become highly explosive!
