摘要： A method for the manufacture for the tubes or shafts of a composite material and having a low weight, whereby a blank of a material that can be pressformed and which has a substantially even thickness of material is subjected to isostatic pressing on or in a formation tool thereby providing a shell or a liner (15) of an intended shape and profile and having a mainly by substantially thickness of material, and on or in said shell or liner (15) another material is applied and is bound, for instance a highstrength material like glassfiber, carbon fiber or aramide fiber, so that the liner (15) and said other material (17) provide a solid integral composite tube or composite shaft. A tube made according to the method can be a barrel, whereby the liner (15) preferably has a conically shaped charged space and is formed with riffels in the race, which rifels have a progressively increased pitch in the direction towards the outer end of the barrel, and whereby the lower rifel portions on the outside of the liner (15) portions are filled withs another material, and the liner is completely covered with preferably highstrength material having a low density, whereby the liner (15) and the other material or materials provide solid integral unit. Correspondingly a shaft can be formed with outer shaft shell of a material that can be pressformed and an inner filler material of a preferably highstrength material having a low density.

摘要： The weapon (10) includes a barrel (13) joined to a barrel yoke (21) in a receiver (14) aft of a front housing assembly (15). The recoil system includes a main recoil spring (30), a secondary spring (23), a buffer group including rods (60), springs (61) and plate (63). A slide bolt assembly (40) includes a slide (41), a bolt (42), a face (43), bolt face levers (44) and actuating pins (45), all within the receiver (50). The bolt face (43) is driven vertically by the bolt face levers (44) to receive a new found round (91), load it and remove and discharge a spent casing (90). The slide bolt assembly (40) travels forward and aft during the firing cycle. On rearward travel it is accelerated rearward by accelerator (70) until reaching the buffer group and transfers its kinetic energy to the buffer group which in turn transfers that energy to the barrel (13) and the recoil spring (30) where it is absorbed without transferring the impact loading to the weapon mount (11).
