Abstract:
The present invention relates to firearms and, more particularly, to automatic or semiautomatic firearms. In a first embodiment, the gas block of the firearm is tightly bound with the upper receiver rather than the barrel, and the receiver serves as a dampening element for gas block vibrations during shooting such that the impact on the barrel is significantly reduced. Fasteners and barrel nuts are used to rigidly position the gas block relative to the upper receiver to best reduce the impact on the barrel. In another embodiment the gas block is attached both to the upper receiver and to the barrel using a support element. Such fixation of the gas block prevents rotation of the firearm and further decreases vibrations of the barrel. In yet another embodiment, the firearm fits interchangeable magazine wells to change the caliber of the firearm.

Claim (Index 33):
The firearm of  claim 1 , wherein the barrel comprises a discharge end whereby a bullet travels toward the discharge end during operation, wherein the barrel is rigidly coupled to the gas block at a first location, and the gas block is rigidly coupled to the upper receiver at a second location, and wherein the first location is located closer to the discharge end than the second location.
