Firearm recoil buffer

Abstract

A buffer for a firearm may include a piston and housing, along with an internal spring and force absorbing materials to reduce damage and wear on a buffer, allowing safe use of a wide range of loads in a firearm, or in the case of some high-power firearms such as 0.308 Win AR variants, providing additional durability to the buffer.

1 . An active firearm buffer, the buffer comprising:
 a body;   a piston slidably positioned within the body;   a biasing mechanism configured to bias the piston to an extended position such that an end of the piston extends from the body; and   a bumper configured to contact a moving portion of a firearm when the firearm is fired.
