US12650275 - Firearm with buffer assembly

A firearm with buffer assembly has a frame, a bolt assembly operable to reciprocate with respect to the frame between a forward battery position and a rearward recoil position, and the bolt assembly including a hydraulic damper assembly. The hydraulic damper assembly may include at least a first portion connected to the bolt assembly. The first portion of the hydraulic damper assembly may be fixed to the bolt assembly such that the first portion does not move with respect to the bolt assembly in response to forces applied in the forward and rearward direction. The entire hydraulic damper assembly may reciprocate with the bolt assembly. The hydraulic damper assembly is operable to provide damping in response to the bolt assembly striking the frame upon reaching the forward battery position and in response to the bolt assembly striking the frame upon reaching the rearward recoil position.

The patent describes a firearm featuring a hydraulic damper assembly integrated with the bolt assembly, which reciprocates between a forward battery position and a rearward recoil position. This design aims to provide damping effects during the bolt’s movement, reducing impact forces when the bolt strikes the frame.

Claim 1

1 . A firearm comprising: a frame; a bolt assembly operable to reciprocate with respect to the frame between a forward battery position and a rearward recoil position; and the bolt assembly including a hydraulic damper assembly connected directly to the bolt assembly to reciprocate with the bolt assembly. a frame; a bolt assembly operable to reciprocate with respect to the frame between a forward battery position and a rearward recoil position; and the bolt assembly including a hydraulic damper assembly connected directly to the bolt assembly to reciprocate with the bolt assembly.
