Well R4 MP7 Electric Rifle Manual

The H&K MP7 is the next generation Sub MachineGun that will be replacing the H&K MP5. It has a high velocity caliber bullet that is armor piercing rounds.

The MP7 is classified as a personal defense weapon (PDW). It went into production in 2001. The current version is the MP7A1. It is compact and light using polymers in its construction.

The proliferation of high-quality body armor has begun to make guns that fire pistol ammunition (such as HK's earlier MP5 or USP) ineffective. In response to this trend, HK designed the MP7 (along with the brand new UCP, which uses the same ammunition) to penetrate body armor, but small enough to be used in place of either a pistol or a submachine gun.

The MP7 essentially operates like a scaled-down assault rifle, with the same action as HK's G36. It fires a specially designed, armor-piercing round with a muzzle velocity nearly as high as that of the 5.56 x 45 mm NATO round used by many modern rifles. This ammunition is unique among submachine guns in that the bullet is made almost entirely of a hardened steel penetrator instead of softer brass or lead. The ammunition is virtually exclusive to the gun (save for the H&K UCP and a planned variant of the Brugger & Thomet MP-9) and also offers low recoil. The round also has a small diameter (it can almost be described as a scaled down .223 Remington), allowing for high capacity in a very small magazine. Even though the round is much smaller in diameter than a 9 mm bullet, its special properties give it comparable stopping power. The projectile is designed to tumble in tissue after penetrating body armor, thus causing more damage than a bullet of this size would normally do. But this is still a point of widespread discussion since the MP7 and its specially designed ammunition have yet to prove themselves in action.

The weapon allows a conventional 20-round or 40-round box magazine to be fit within the pistol grip (the former being comparable in size to a 15-round 9 mm magazine, while the latter compares to a 30-round 9 mm magazine). The weapon features an ambidextrous fire-select lever and rear cocking grip. It has an extendable stock and a folding front grip. It can be fired either one-handed or two-handed.
