I Love My Break Barrel Air Rifle
A Short History of the Break Barrel Air Rifle
Air guns represent the oldest pneumatic firearms technology.
The oldest existing mechanical airgun, a bellows airgun dating back to about 1580, is in the Livrustkammaren Museum in Stockholm.
This is the time pegged as the beginning of the modern airgun.
Air rifles have come a long way since then.
My First Break Barrel Air Rifle Was A Gamo Shadow
Spring-piston air guns are able to achieve muzzle velocities near or greater than the speed of sound from a single stroke of a cocking lever or the barrel itself.
The difficulty of the cocking stroke is usually related to the power of the air rifle or gun, with higher muzzle velocities requiring greater effort.
Spring-piston air guns operate by means of a coiled steel spring-loaded piston contained within a compression chamber, and separate from the barrel.
Cocking the airgun causes the piston assembly to compress the spring until a small hook on the rear of the piston engages the sear.
Pulling the trigger releases the sear and allows the spring to decompress, pushing the piston forward, thereby compressing the air in the chamber directly behind the pellet.
Once the air pressure has risen enough to overcome any static friction and/or barrel restriction holding the pellet, the pellet moves forward, propelled by an expanding column of air.
All this takes place instantly, during which the air heats to several hundred degrees and then cools as the air expands.
