Welcome to the Army Rumour Service, ARRSE

The UK's largest and busiest UNofficial military website.

The heart of the site is the forum area, including:

  1. Has anyone fired/handled the 4.6mm MP7 ? what did you think of it ?
  2. Caliber: 4.6x30mm HK
    Weight: 1.5 kg empty
    Length (stock closed/open): 340 / 540 mm
    Barrel length: 180 mm
    Rate of fire: 950 rounds per minute
    Magazine capacity: 20 or 40 rounds
    Effective range: 150-200 meters

    The HK MP7 Personal Defense Weapon (PDW) is a member of a relatively new class of small arms, called Personal Defense Weapons (PDW; such specialized weapons are build since the start of WW2). The PDW are intended, as name implies, to be a defensive sidearm for second-line troops, vehicle crews and other military personnel who normally not issued with assault rifles. Previously, these troops were issued with pistols or submachine guns, but proliferation of body armor in recent years made those guns ineffective. The first firearm, intended as "the new age PDW" and offered in that class was Belgian-made FN P90, and it had special low-impulse, high-velocity ammunition, capable of penetration of current military body armor and helmets at ranges of 100 meters and beyond, while being much smaller and lighter, than assault rifle. The HK MP7, originally known simply as HK PDW, is another entry in the PDW class, and thus is a direct rival to FN P90.

    The HK MP7, first announced in 2000, entered production in 2001 and, by early 2007, is officially adopted by German military, as well as some German special police units, such as KSK, and also offered for export sales. The British Military Police issues HK MP7A1 to its personnel since 2005, and it is believed that some South Korean special forces also use MP7A1.

    The HK MP7 submachine gun / personal defense weapon has layout of a typical compact submachine gun (or a large pistol), with magazine being inserted into pistol grip, with folding forward grip and telescoped buttstock. The action of the MP7A1 is somewhat unusual for weapon of such small size, since it is gas operated, rotating bolt design, which strongly resembles the action of the HK G36 assault rifle, suitably scaled down. The ambidextrous fire mode selector/safety switch allows for semi-auto and full-auto modes. MP7A1 it designed to fire special, high velocity ammunition, 4.6x30mm, that looks like scaled down rifle round. That ammunition is unique to the MP7 and another HK weapon, the HK UCP / P46 pistol.
    The receiver of MP7A1, along with integral pistol grip, is made from the polymer with steel reinforcements. Top side of the receiver hosts a Picatinny-type accessory rail for sight mountings. Standard sighting equipment is usually a set of low-profile open sights on quick-detachable mounts, plus a collimating (red-dot) sight Additional rails can be installed on either side of receiver, next to its front end. The MP7A1 could be fired single-handedly, or using both hands, either like the pistol or using a front grip. Telescopic buttstock can be extended to give additional stability. With buttstock and front grip are collapsed, the MP7 can be carried like any big pistol in the special holster, and can be effectively used in close combat.

    The 4.6x30mm ammunition is loaded with pointed all-steel bullets with brass jacket. Bullet weight is 1.6 gram (25 grains) and the muzzle velocity is 725 m/s (ca. 2400 fps). Manufacturer claims the 100% penetration of the CRISAT body armor (1.6mm of Titanium plus 20 layers of Kevlar) at the distance of 200 meters. Other types of ammunition, including tracer, frangible, spoon-tip (rapid-tumbling for use against unarmored human targets), blank and trill (inert) also available for MP7A1; ammunition is currently manufactured in UK by BAE Systems / Radway Green plant.
  3. some more info and piccies here
  4. This has been described in great detail in "Weaponology",( the rapid fire edition) on Discovery Channel. The prog shows the weapon in action too.

    Ive handled one(havent had a chance to fire it) and i must say it is everything you need for a pocket sized rocket. It is well balanced enough to fire single handed if you really needed to, but big enough to handle properly with the stock and foregrip deployed. The rounds are the sort that will leave your body armour looking like a collander and your torso full of tiny little holes leaking the red stuff. With 40 to a mag there will be lots of them to!
  6. Sounds like a lot of penetration for a 1.6g bullet, but it's not as if I'm sat here with a calculator and references to work it out. I know it'll be a functionish of ½mv^2/d^2 . but 725m/s doesn't sound super fast. Most supersonic (pointy) bullets do that... and a 7.62 NATO weighs in at 12g - thus would have 7 or 8 times that kinetic energy. I can't imagine a 7.62 going through 10mm titanium and 120 layers of Kevlar. But there you go... if the manufacturer says it can, it'd be worth a try. Flechete perhaps not FMJ?
  7. I've had a brief pop on one. Sights are OK, recoil is non existent and the stock is uncomfortable. Probably OK for those who are usually issued a Browning 9mm.

    The body armour penetration is interesting, but actual stopping power would presumably be the key - it IS a very small round.
  8. I remember seing this a few years ago when it was on trials.This was supposed to be issued to tank crews and attached arms,but as H&K were re-inventing the L85/L86, they offered a carbine version and as that was the cheaper option i guess.Thats what we got.I did have the pleasure of firing it at the factory in Germany and prefered the MP7 to the carbine(i broke it).A weapon i would like to see come into service is the HK416,but thats another topic.
  9. Thanks folks.

    I collect ammo and have 6 different types of load so far.

    Am I an ammo anorak, guess i am. :D
  10. Teflon composite bullet perchance?
  11. Both are wrong, it has a pointed steel core and a brass jacket. It has an extremely small cross-sectional area, which helps in penetration. Incidentally, 5.56mm is much better at piercing armour than 7.62 mm for the same reason.
  12. Rememeber years ago seeing an SMG fitted with a silencer, very scary as you only heard the working parts moving and a small popping sound. Old technology now though!!
  13. MP5-SD?
  14. Yes but there was also one for the Sterling SMG.
