Abstract From the Canadian patent
A firearm recoil system that reduces the maximum recoil force felt by the shooter. The recoil force applied to the shooter's shoulder is interrupted by tapping off explosive gases produced by firing a cartridge and directing the gases into a gas cylinder to actuate a piston rearwardly and at the same time provide a forward force to the firearm opposite to the rearward recoil movement of the firearm. The rearward piston movement is slowed down by compressing air trapped within the cylinder and then venting the compressed air so that the remaining recoil energy in the piston is gradually phased out. This results in a substantially lesser peak or maximum shoulder force.

Why it's free to use
- Granted January 1, 1980. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended January 1, 1997.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
