What exactly are the advantages and disadvantages of calf style and traditional rifle designs?

Calved, or stockless. The magazine stock is integrated. Advantages: 1 short, often the barrel of the same calf type to be about 20cm less than the butt type. Seat car when not afraid of bump bump bump. The moment of inertia is also small, fast aiming has a slight advantage. 2 light, conducive to one-handed magazine change. Disadvantages: 1. can not quickly change hands, not conducive to street fighting and CQB (except F2000) [ Transferred from the Iron Blood Community / ] 2. barrel by the wood covered by a larger area, affecting the heat dissipation 3. most of the barrel is in the grip position, affecting the heat dissipation, but also may lead to the wood guards hot hand and affect the shooter shooting and even due to the impediment of the combat 4. in the trigger near the opening of the cooling holes can easily lead to sand and foreign objects into the cause of failure 5. the stock is large, not conducive to the shooting of the gun, but can not be used as a weapon. The large size of the buttstock does not facilitate tactical maneuvers by soldiers wearing defensive gear and does not allow for close-quarters hammering. 6. The magazine position slows down magazine changes. 7. The aiming baseline is short. 8. The backward position of the shell thrower affects rapid pointing (with the buttstock clenched under the armpit). 9. The backward position of the shell thrower affects shooting from the waist (the arm may obstruct the shell thrower). 10. The backward position of the shell thrower affects shooting from the shoulder. 11. The smoke may affect the shooter during shoulder fire. 12. The position of the case thrower is backward, and the shooter may be affected by the smoke when shooting against the shoulder. 11.

The position of the magazine catching shooter is inconvenient to use. 13. The magazine is close to the shooter, and the damage to the shooter in case of a breechblast will be more serious than that of the conventional structure. Advantages: 1) It is easy to shoot accurately, easy to control the shooting angle and shooting speed. 2) The stock is small, which is good for close-in shooting. 2 butt small, conducive to close combat 3 reasonable structure, good reliability (M16 is often due to ammunition residue caused by malfunctions, not foreign matter infiltration)

Disadvantages: 1 is not to make the march to carry, increase the weight of the soldiers. (Folding stock can be solved) Aiming height does not lie in the buttless and butt. Depends on which type of sight is used If you use a carry handle sight, the eye aiming height is naturally high. If you are using a carry handle sight, your eyes will naturally aim high, and you will be easily exposed. If you use a normal mechanical sight or a mirror type sight (telescopic, internal red dot), the head aiming height is lower. The head aiming height is a little lower
