A light-weight, shoulder-firable, armor-penetrating gun characterized by a recoiling barrel confined to coaxial movement by a pair of longitudinally spaced bushings within the gun housing, the recoiling barrel being adapted to carry rearward the elongated bolt carrier containing the bolt for compressing the recoil spring, and a stop mechanism associated with the barrel and the housing for limiting the rearward travel of the barrel for early disengagement between the barrel and the bolt carrier, and a barrel spring in the front of the housing for returning the barrel to its normal battery position.

A shoulder-firable gun comprising: (a) an elongated housing having a front portion, a rear portion, an upper portion, and a lower portion, said rear portion comprising a shoulder stock, (b) trigger mechanism in the lower portion of said housing, (c) an elongated bolt carrier received within said hou
A shoulder-firable gun comprising: (a) an elongated housing having a front portion, a rear portion, an upper portion, and a lower portion, said rear portion comprising a shoulder stock, (b) trigger mechanism in the lower portion of said housing, (c) an elongated bolt carrier received within said housing for longitudinal, reciprocable movement, said bolt carrier having a coaxial forward-opening bolt cavity, (d) an elongated bolt slidably received within and projecting forward from said bolt cavity, the front portion of said bolt comprising radially projecting bolt locking lugs and an elongated reciprocable coaxial firing pin, (e) said bolt cavity having a rear seat for engaging a rear portion of said bolt when said bolt is fully retracted within said cavity, (f) bolt spring means in said bolt carrier normally biasing said bolt forward, (g) cam and slot means interconnecting said bolt and bolt carrier to provide limited rotary movement of said bolt relative to said bolt carrier during longitudinal movement of said bolt relative to said bolt carrier, (h) an elongated recoil spring within said rear portion of said housing and in coaxial alignment with and behind said bolt carrier, (i) an elongated barrel comprising a rear barrel portion having a barrel chamber and terminating in an enlarged bolt locking collar, (j) said bolt locking collar having radially inward directed collar locking lugs for engaging and disengaging said bolt locking lugs in a battery position, (k) a front bushing fixed in the front end portion of said housing for slidably receiving said barrel for longitudinal reciprocable movement, (l) a rear bushing fixed in said housing substantially behind and in coaxial alignment with said front bushing and in front of said bolt locking collar, (m) a barrel travel stop member fixed within said housing between said rear bushing and said front bushing and encompassing at least a portion of said barrel, (n) an abutment member fixed on and substantially encompassing said barrel between said stop member and said front bushing to engage said stop member to limit the rearward movement of said barrel, (o) barrel spring means connecting said barrel to said housing to bias said barrel forward to a battery position, (p) said bolt locking lugs counter-rotating and disengaging said collar locking lug after said abutment member engages said stop member during the rearward travel of said barrel, whereby said bolt carrier continues its rearward movement against the action of said recoil spring while said bolt rotates forward relative to said bolt carrier, and said barrel is biased forward to its battery position by said barrel spring.
