The 1960s the American puted foward a “ Volley plan ”,but due to the small mass
of these sub-warhead,bad for long-distance battle,especially after the small-caliber
automatic weapons,“Volley Plan” is harderbreaktthrough.The G11 of German rifle
with caseless cartridge,designed a rotating actionf for cartridge into the breech of
the trip,especially small,the firing rate of 2000 rounds/min or more, and
three-round burst institutions to control, very close to “Volley Plan”,but was
forced to stop due to various reasons .It was very regrettable. The same idea was
achieved by AN94 desgined by Russia. AN94 uses the traditional bullets,but can
be two rounds of high-frequency burst. AN94 can be thought a milestone of the
modern assault rifles. But its complex structure, the high cost, the use of many
new structure makes the cost of training a substantial increase to result from
large-scale equip our troops, which restricts the development of the AN 94
In this paper, the “回”shaped action, using a new “回”shaped structure, the
bolt deflection for shells greatly shorten the trip for bomb, making the rifle can
shoot in frequency, using the structure of magazine recoiling with the reveiver to
ensure that the third round of high-frequency burst of the bomb process can be
completed. Using traditional bullets, but can also achieve the effect of the
three-round burst firing in the G11. The same time the structure of “回”shaped
action is simple an low cost of production, allows the rifle to avoid the enbarrassing
