The recoil energy is generally absorbed by the mechanism which produces the counter-recoil force, and is dissipated as heat.
Likewise, the recoil energy given to the firearm is affected by the ejected gas.
The recoil spring and the mass of the slide are enough to buffer the recoil energy of the round.
In the same 8 pound rifle, a 150 grain bullet at 2910 ft/s will only generate 17.6 foot pounds (23.9 joules) of recoil energy.
At each end of the pump tube, there sits a 100-ton rail-mounted sled to absorb recoil energy from firing.
This decreased recoil energy made possible a reliable, lightweight semi-automatic rifle with existing technology.
The recoil energy is reduced by its long course.
Some of the recoil energy is used to prepare to gun for the next round.
Wheel plates were added to absorb more recoil energy and to help the gun cross soft ground.
Trying to figure the net recoil energy of a firearm (also known as felt recoil) is a futile endeavor.
