Bullpup

The term Bullpup indicates an architecture (mechanical configuration) general of a Firearm intended to reduce its overall length without sacrificing that of the gun. The room is for that located very at the back. On a rifle, for example, the mechanism as the charger will be usually behind the handle, therefore employ a space usually occupied by the only stick. As illustration, FAMAS, arms bullpup, 75,7 cm is long just like the Colt M-4 (version shortened of M16, arms not bullpup) but the gun of this last measures 12 cm less.

History

The originator of the rifle with bolt Thorneycroft employed the first this architecture in 1901. Since the appearance of a model of Gun patented by the French Henri Delacre in 1936, a growing number of originators of semi-automatic weapons adopted it. A Fusil of attack confining a ammunition of 7,62 mm was developed in 1946 in Tula (Soviet Union) on an experimental basis but did not enter in service. The the United Kingdom was equipped the first of a rifle with attack bullup , the EM2, for which the studies had begun in 1944 but chose finally traditional FAL of design because of the adoption of the standard cartouche of NATO. FAMAS and the Steyr AUG, appeared appreciably at the same time were the first weapons bullpup has to be adopted successfully by armies.

Constraint

This configuration poses a certain number of difficulties rising in particular from the position from the room, very near to the face of the gunner thus, inter alia, of the mode of ejection of the cases. A weapon bullpup can be shouldered only one side, which prohibits to him a priori to be employed by a droitier as by a left-handed person thus constitutes a logistic embarrassment of order. So some weapons such qu E L SAR-21 can be shouldered only on the right, the solution most current, present on FAMAS and the Steyr AUG, consists of a reversible mechanism which, to the price of a disassembling of the weapon, offers average to decide side of ejection of the cases. FN P90 and FN F2000 conceal a innovating solution because they respectively eject the cases to the bottom and forwards, which makes for this reason any disassembling useless.
