MP5+5.7=MP5.7 ??? Anyone?

Piston Driven · Post by **Piston Driven** » 27 Oct 2012, 22:54

So, crazy, but a mp5- 5.7? We all know their isn't a chance Germany won't produce such belgian blasphemy but could we :skep: ?? How many hundreds of hours would it take? Could we modify a $400 .22 mp5 to such degree and mix match it with a $500 MPA 5.7 MAC? :thumb: Sorry for all the question! Thoughts, solutions, love, Ideas???? :ponder:

Post by **blueorison** » 28 Oct 2012, 06:12

- Why?

Because the P90, even out of polymer, is better-made than an MP5.

HK fanboys probably won't sleep well unless they start a flame war, now.

Arguably true, I think of it as a personal challenge :thumb: and PERSONALLY prefer the MP5 ergonomics and in theory it could be a lot cheaper but a lot more dangerous :lmao: !

srt-4_jon · Post by **srt-4_jon** » 28 Oct 2012, 12:35

all you would need to do is redesign the magazine, magwell, bolt, locking system, recoil system, and barrel. sure sounds cheap to me. I wonder why no one has done it yet?

:thumb: Thats what I was thinking'... Sounds like easy redneck innovation !! I think the eject port would give you trouble though..... :ponder:

I wouldn't say the MP5 is any less well made than a P90 is. The worksmanship and quality is equal. If you have ever handled a real, military MP5, particularly their PK and SD models. And the MP10, well that is a fun and hot gun.

The P90 is great too.

P90, even out of polymer, is better-made than an MP5? Sorry Blue! Not an H&K fanoby by no means but the PS90 or P90 is no where near the quality of weapon the MP series is....

Piston Driven · Post by **Piston Driven** » 31 Oct 2012, 13:11

Funny me an Irish and toylsr agree! But the MP5 series in general just has decades more experience and pounds of more metal! The main edge in the p90 vs mp5 debate is the 5.7. And I personally love the Mp5's ergonomics, the folding stock the whole shebang !!! I think the Mp5.7 would be better than both rifles!

Piston Driven · Post by **Piston Driven** » 31 Oct 2012, 13:13

:topic: Enough arguing ! All can agree its cool! So any one have any clue HOW?

toyslr · Post by **toyslr** » 01 Nov 2012, 06:24

Dependability / Reliability goes to the MP Series. The 5.7 is a better round than anything the MP is offered in, other than maybe the UMP in .45

Nahhh, 5.7 great ballistics and fraction of recoil of .45! But the .45 does have more knock down power...

When it's so powerful it knocks you down.

:laugh: Exactly, self explanatory! The foot lbs of force it hits you with is general stopping power if I'm not mistaken... All around 5.7 a great round, and superior to .45 in most applications but its not why but how?? Any attempts ever at it?

It'd be easier to take a $600 HK33 clone and down-scale its internals to the 5.7x28mm than to try to shoe-horn the 5.x7x28mm into firearm designed for .22LR (or 9mm, 10mm, or .45)

Not that it would be "easy." (and HK be still be HK and would still hate you.)

Thanks for going to the OP! Hk 33 or Hk 53 would be good as well!! Id probably scalage a ar 5.7 barrel and machine a 5.7 bolt possibly, or modify a .223 hk 53 bolt (a lot )... The more though I dedicate to it the harder this gets! :lmao: Hk's can seem to hate you some times!

I find it amusing when I hear the various "knock down power" definitions rendered by people going mostly by what they read in a book or on the internet or what they saw in an action movie. I'm sure most of them have never been hit by one of those "Man Stoppers" they write about.

I was working as a DOD contractor in a middle east country and was caught in a terrorist ambush on a local police checkpoint. I was hit by a 7.62×39mm round from an AK, and while it did f**k me up badly, I wasn't "knocked down" or "go flying through they air" from the foot lbs of force of the bullet. I wasn't out of fight until it was all over. I didn't realize that I was hit until I saw the hole in my chest and started having real trouble breathing. I'm living proof that the body can take a lot of damage by one of these great "knock down power" bullets and not get "knocked down".

I just think that before you write about things that you think you know about, maybe you get some info from some LEOs or Combat Vets who have seen the results of the bullets that you want to write about up close. I'm sure that I'm not the only forum member with a story to share.

Just my 2 cents.

:thumb: You gotta a lot of balls sir and tough story! It doesn't mean every bullet "that has stopping power will knock you down" stopping power is also sometimes considered the ability to stop a object, which I'm assuming it slowed you down! The 7.62x 39 has more of a rep as a hole puncher, exerting so much force it pierces through skinnier people. Hence the Broskies made the 5.45 to tumble, be nasty and kill. I assume you were also wearing BA which could have been a life saver too. Most people have different definitions of "knock down power" but the .45 is always pretty high on the list, at least higher than the 5.7. I've had dozens of friend who faced a lot of combat contest to the "man stopping" ability of the .45. :ponder:

Haha well said, back to OP, we can start a stopping power debate in another thread, any other insight in creating a 5.7 Mp5 or Hk 53, 33?? :ponder:

Sorry if I confused the issue. All I was trying to do was point out that neither the force of a .224, .45, or a 7.62 is going to "knock a man down". Am I wrong? I just think that the "knock down power" that people talk about is largely a myth. Proper shot placement by just about any round is more important than the round itself.

Again just my 2 cents.

it isn't the answer you wanted to hear so you keep on asking like it's going to change.

The .45 UMP comment was a JOKE! I think that is one of the sexiest weapons out of the H&K line up.
5.7 x 28 is superior in ballistics but don't see FN giving them permission to produce ( if it would even be needed?)

No permission needed to make a gun in 5.7x28.
