A recoil assembly for a rifle includes a barrel assembly, a bolt, bolt actuator, and a buffer assembly. The barrel assembly includes a barrel secured to a barrel extension. The barrel assembly is slidably received in the receiver and the barrel extension is coupled to a hydraulic buffer assembly located below the barrel extension. The hydraulic buffer assembly is configured and arranged to arrest rearward movement of the barrel assembly when the rifle is fired. An op-rod spring is coupled to an op rod extending that can be actuated by a gas piston assembly on the barrel. The op-rod spring is configured and arranged to arrest rearward movement of the bolt assembly.

A recoil mechanism has a hollow cylinder having a first portion adjacent to a closed end having a first inner diameter and a second portion adjacent to an open end having a second inner diameter, and an outwardly facing flange at the open end thereof. An outer spring is positioned over the hollow cylinder and has a second end in contact with the outwardly facing flange. A rod assembly includes a rod coupled to an endplate at a first end thereof and an enlarged portion towards a second end thereof, a washer mounted on the rod between the enlarged portion and the endplate, and a rod spring mounted over the rod between the small washer and the endplate. Moreover, the rod assembly is positioned within the hollow cylinder by inserting the second end of the rod into the open end of the hollow cylinder.

A disrupter includes a barrel through which a projectile is fired; a barrel housing including a sleeve, the sleeve configured to receive the barrel and allow movement of the barrel therethrough; a frame on which the barrel housing together with the barrel may be selectively pivoted, the barrel configured to move relative to the frame during recoil of the barrel; and a stand on which the frame is supported, the stand including a pair of telescopic legs configured to extend in a direction parallel to a surface on which the disrupter is positioned, wherein telescopic extensions of the legs extend in a direction opposite a direction of firing; wherein the telescopic extensions are configured to extend prior to the firing and are configured to telescopically collapse during recoil of the barrel, the telescopic construction accompanied by a resisting force configured to absorb recoil energy as the telescopic legs collapse.

Because of a clearance between a barrel supporting member and a barrel, a rotational movement of the barrel is not always constant. Thus, trajectory of a bullet is misaligned. A counterweight 40 is located upper than a barrel 10, and rings 61, 62, which are support portions, are located nearer to the counterweight 40 than a gravity center of the barrel 10. Since the barrel 10 is located lower than the counterweight 40 and engaged with a lower surface side of a gear 30, when a bullet is shot and the barrel 10 is moved backward, a force to rotate the barrel 10 itself clockwise is imparted by a circular surface shape of the gear 30. The barrel 10 receives a force to be rotated clockwise from the gravity center position, the ring 61 and the ring 62, and the barrel 10 is in contact with the inner surface of the barrel supporting member 50. Thus, in spite of the existence of the clearance, the barrel 10 is not displaced in the barrel supporting member 50.
