The LAV On The HK MP7

Definitely my favorite looking PDW in existence:

4.6x30mm?  HK… come on guys I know we suck and you hate us, but why is this not offered in mainstream calibers and in gun stores everywhere?

Larry Vickers is far less annoying than he used to be.  He must have lost the “I’m important and famous, pay attention to me” attitude I talked about before along with the weight.

Did they even leave a “safety trigger pull” in at 2:23?  That’s the kind of embarrassing rookie shit I do on occasion.

2:54 – “If you don’t think this gun is cool, then you got an issue homes” – *Facepalm* … damn Larry, you were doing so good up to this point. (See general life rule #1).

It sounds like one of those BB shooting carnval games, Especially at 1:45. Pretty nifty.

I do my best not to buy much that is proprietary. I’ve been burned more than once on that. I have a B&D electric hand saw that is effectively useless because I can no longer get blades for it. It only cost about $40 and looked OK at the time.

If I were to spend several hundred dollars on a weapon — I want to be able to know I can get bullets on without having to depend on a single source.

It does look like a nice weapon though.

Does FN hate us with their 5.7? Does Glock hate us with the GAP? Did T/C hate me when I bought a .256 magnum barrel? Did several makers hate us with their 5mm rimfires? This list could be nearly endless.

W/E you can’t own a post ’86 unless your a FFL or LEO so I could care less about the gun. The fact that you can’t go to the store and buy the round seals the deal. Obliviously the sound has been adjusted comparing suppressed vs non suppressed. The round is supersonic and would be loud as fu**.


B-man May 6, 2012 at 04:13 am

I have a brother and his police unit jsut got issued these. I told him that I must shoot it. He was saying that it was difficult for the police to get ammo for this and they could hardly qualify with them let alone take them to the range and practice with them. When they do get some in, you know im going to the range with this baby!


Komodo Saurian May 6, 2012 at 06:31 am

Well then, I guess I have an issue then.

Rare gun firing an obscure caliber? Nah, not cool.


bbmg May 6, 2012 at 08:16 am

What I can’t stand about the 4.6mm is that it’s basically a scaled down 5.56mm round. If you’re going to make a proprietary round, go crazy with it, make something at least slight radical. The makers of the CBJ-MS had the right idea:

Alternatively, most people are already using 9mm pistols and submachineguns – so why not make the effort do develop a new bullet for the 9×19 cartridge? A proper discarding sabot round need not be sophisticated or expensive, a simple tool steel 6mm penetrator in a one piece synthetic sabot like the CBJ will give the recoil reducing and armour penetrating benefits of the MP7 and P90 on a much lower budget, while still allowing you to shoot conventional ammunition. At least FN when through the effort of making a relatively radical new compact and high capacity weapon to gi with their new round…


JC May 6, 2012 at 08:25 am

I can’t find any good info on the stopping power of the 4.6mm round. I know it is designed to defeat body armor, but it is just such a tiny round.


Jon Hutto May 6, 2012 at 09:10 am

4.6x30mm is the HK equivalent of 5.7x28mm from FN. Both have the same purpose, more rounds in a given space.


Will May 6, 2012 at 10:46 am

The caliber and the weapon is meant for non-combat military units (transportation, engineer etc..) so they have something more than a pistol to defend themselves with. This was previously solved by using 9mm SMG’s like the MP5 or the Uzi. Thing is, bodyarmor has rendered them almost useless on a conventional battlefield. So, you get weapons like the MP7 and the P90, using a small high-velocity round that has no problems defeating bodyarmor.
Granted, the past ten years hasn’t seen many conflicts where western armies face a well-equipped conventional enemy…


Jeff May 6, 2012 at 03:53 pm

I’m curious, is the 5.7 penetration up to level III or does it stop at soft body armor? because if its only good for IIIA and below, simply loading 9mm+P+ would probably be more cost efficient.


Church May 6, 2012 at 10:33 pm

Well put. My opinion/thoughts exactly.

10.5″ AR15 SBR> MP7

I got a issue, homes.

Jess Banda May 6, 2012 at 12:16 pm

Last time I heard some use the word “homes,” was in ’87.


hydepark May 6, 2012 at 12:21 pm

Okay, for the record guys the 4.6×30 IS NOTHING LIKE the .17HMR. For starters, go google some ballistics charts. This guy may think he knows everything because he’s gotten to shoot the thing, but wow he doesn’t.


Critter May 6, 2012 at 05:00 pm


more H&K pretention.

the only hard to find guns in obscure calibers that interest me have to be at least 100 years old.

for everything else there’s SBR AR15.


Byron May 6, 2012 at 05:56 pm

I agree. If they’re going to a “roughly equivalent to .17HMR”…why not do .17HMR?


bbmg May 7, 2012 at 02:35 am

It would be interesting to combine the 17HMR with a weapon that can lay down a high volume of fire like the American 180 or MGV-176. While an individual round might not do much damage, one second on the trigger on something like this firing at 1200 rpm would put 20 rounds downrange, and given the low recoil it would be safe to assume that the majority of them would be on target.


Byron May 6, 2012 at 06:01 pm

Wonder what could be done with discarding sabot 9mm pushing something like a 55g 5.56 or 6.5mm. That way you could get high velocity stopping power combined with commonality and the ability to practice with standard fmj. I’d imagine the load that would push a 115gr FMJ 9mm would be hot nuts at 55gr.


bbmg May 7, 2012 at 02:47 am

In order to ensure reliable operation in a 9mm weapon, the external profile of the round would have to resemple the round nose FMJ. Because of this I doubt it would be practical to take an existing assault rifle bullet and put it in a sabot. Also, a rifle bullet that is more elongated will need a faster twist rate than what 9mm weapons offer in order to be adequately stabilised.

Since you’re not touching the rifling, the projectile does not need a jacket, it can simply be made from solid steel, and can simply be a 7mm diameter cylinder with a pointed nose, making it cheap to manufacture along with a synthetic sabot a la Remington accelerators.

The only disadvantage is that steel is less dense than lead, so a lead core might still be beneficial to retain a good ballistic coefficient, while retaining a thick wall of steel preserves the hardness needed to penetrate armor

A tungsten core would obviously offer more benefits in terms of hardness and density, however it would be more expensive, and if the object is to penetrate body armor it would be a needless expense.


Lance May 6, 2012 at 07:32 pm

I’m Larry Vickers’ long lost son. If you see him just let him know he’ll need to swing over and pick me up ASAP.


Toadstone May 6, 2012 at 09:06 pm

No way, the Magpul PDR is way cooler… oh wait, you said “in existence”. Nevermind.
Seriously, though. What the hell, Magpul? PLEASE make the PDR. What the hell.


bbmg May 7, 2012 at 03:02 am

Apart from being “cooler”, it’s also chambered for the standard 5.56mm round


Ben Branam May 7, 2012 at 10:22 am

The last comment was great. You know we are all thinking something like that from time to time.


boris May 8, 2012 at 11:01 am

What is he on about? “because its so small you are going to need to put a lot of rounds down” the round can defeat body armor so why do you need more than one. im sorry but one round through the centre of mass on anyone would put them down. what is wrong with aiming.
