Claim 3:
4. A firearm recoil mechanism operative to couple with a firearm, the firearm recoil mechanism comprising:
a Bolt Carrier Group coupled with a front spring plate,
the front spring plate slidably coupled with a first Guide Rod and a Second Guide Rod, wherein the first Guide Rod and the Second Guide Rod operative to extend within a left channel and a right channel formed in an Upper Receiver and to extend through the front spring plate;
a First Recoil Spring and a second Recoil Springs engaging with the front spring device, wherein the first Recoil Spring is disposed around the first Guide Rod, and wherein second Recoil Spring is disposed around the Second Guide Rod;
a piston integrally coupled with the front spring plate and the Bolt Carrier Group; and
the Upper Receiver forming a center guide channel in which the Bolt Carrier Group is operative to move through in a first direction to coil the first Recoil Spring and second Recoil Spring on the first and Second Guide Rods respectively in response to gases generated upon a firing of a bullet to push the piston and front spring device in the first direction and to move the piston and front spring plate in a second opposite direction in response to a recoil of the first Recoil Spring and second Recoil Spring on the first and Second Guide Rods,
wherein the piston has threads at one end and the Bolt Carrier Group includes a threaded receiver, and wherein the piston is integrally coupled to the Bolt Carrier Group by screwing threads of the piston into the threaded receiver.
