MagPul PDR 5.56 PDW SMG

[lup]

MagPul PDR 5.56 PDW SMG można by rzec "mała masada" ;)

 

To coś nowego czy ja coś przegapiłem?

Najbardziej interesujące to faktycznie "zasilanie" nabojem 5.56x45mm NATO.

 

QUOTE("Defense Review")

MagPul is currently in the process of developing a 5.56x45mm NATO/.223 Rem. NATO (5.56mm NATO) bullpup PDW (Personal Defense Weapon)-sized subcarbine/SBR (Short Barreled Rifle) called the "PDR", which stands for "Personal Defense Rifle". The MagPul PDR™ is approximately the same size as an FN P90 PDW, yet surprisingly lighter in weight, without resorting to a proprietary sub-5.56mm PDW caliber like the 5.7x28mm cartridge developed by FNH (FN Herstal) for the P90 PDW or 4.6x30mm cartridge developed by Heckler and Koch (HK) for the MP7A1 PDW.

 

In fact, that's the whole idea behind the MagPul Personal Defense Rifle (PDR)--give the warfighter a lightweight 5.56mm NATO weapon in a compact PDW-sized package. Since it doesn't require special ammo (i.e. a proprietary cartridge), there are no ammo supply and procurement difficulties, other than the occasional shortfalls of 5.56mm NATO ammo supply, due to inadequate U.S. ammo production capability in the face of an ongoing war (Iraq and Afghanistan).

 

DefenseReview got to view and handle (and photograph) a MagPul PDR ™ non-functional prototype mockup at the MagPul booth at NDIA Small Arms Symposium 2007. The version we handled utilized a P90-like receiver (with regard to physical appearance), except the PDR will utilize box magazines. In fact, Drake Clark, MagPul's PR officer, has informed me that the PDR will be able to utilize standard 20 and 30-round NATO 4179 STANAG USGI AR-15/M16 box mags as well. Mr. Clark also showed Defense Review a prototype molding for a different configuration that incorporates a more conventional (and U.S. military-preferred) vertical foregrip. DefenseReview prefers this vertical foregrip setup/config. It's an interesting concept, and we look forward to seeing how the functional PDR prototype performs.

 

The PDR ™ is slated to incorporate polygonal rifling, which increases bullet velocity over traditional rifling by creating a better gas seal around/behind the bullet, and allowing less gas to escape around the bullet as the round is fired. Heckler & Koch (HK) and Glock have helped to make this type of rifling popular and prove the concept.

 

Defense Review is particularly interested to find out how controllable the weapon is in full-auto. Since th PDR has a projected weight of 3-4 lbs (approx.), full-auto controllability is likely to be an issue unless some kind of recoil attenuation/mitigation system is utilized. The MagPul team might also consider some type of mechanical or hydraulic rate reduction system to reduce the weapon's cyclic rate/rate of fire (ROF) to the 500-650 rpm range, if the PDR's natural cyclic rate is higher (unknown). A recoil mitigation system, combined with a cyclic rate reducer, should do the trick, provided that doesn't increase the weapons overall weight by too much or reduce the weapon's reliability or durability.

 

For the recoil mitigation system a.k.a. recoil attenuation system, DefenseReview would recommend that the MagPul PDR development team contact legendary infantry small arms designer Jim Sullivan (L. James Sullivan) of Arm West, LLC. Mr. Sullivan is the master of recoil attenuation/mitigation a.k.a. "recoil reduction" in lightweight small arms (specifically, lightweight, man-portable machine guns). There is simply no one better.

 

Mr. Sullivan designed and developed the Ultimax 100 5.56 LMG/SAW (Light Machine Gun/Squad Automatic Weapon), which is the lightest and best 5.56mm NATO LMG/SAW in the world, today, and has been ever since it's initial introduction (in 1982, if I'm correct). That's right, the Ultimax, which proved that a lightweight machine gun could outhit a significantly heavier machine gun (in the same caliber) on full-auto, is approx. 25 years old, and it will "house" (i.e. significantly outperform) the FN M249 SAW in pretty much every infantry combat-relevant area, including reliability and durability in adverse conditions under high round count, controllability on full-auto, reloading speed, weight, etc. Development actually began on the Ultimax 100 in 1978.

 

For the cyclic rate reduction system, MagPul might want to take a look at the FERFRANS Specialties rate reduction system, which they developed for their SOAR (Special Operations Assault Rifle) AR-type subcarbines/SBRs (Short Barreled Rifles). It's possible it can be utilized or adapted for the MagPul PDR (unkown at present).

 

In any case, the MagPul PDR is indeed interesting, and we look forward to running one at the range when/if it's introduced.

fotki widziałem też na arnim dla tych co zarejestrowali sie na forum

W wersji z chwytem a 'la P90 wygląda prawie jak giwera z Ghost In The Shell :)

A w pierwszym wariancie widac podobienstwo do HK :P

rzeczywiście, dodać tylko "górę" z P90, normalny mag i mamy prawie to :)

[wantacz]

Hmmm... upper reciever od P90 ale raczej z wersji z kolimatorem żeby było łatwiej przerobić coś na ten styl:

I zamiast kolimatora założyć mechaniczne przyrządy celownicze, oraz zrobić lekką kosmetykę body i mamy to:

Hmm... Doskonale... Kto się podejmuje? Z rozkoszą obejrzę ewentualne efekty. Ostatnio jestem wręcz chory na replikę jakiejś Shirowowej broni. Choćby i CZN-M22.

też by uszło;]

Padło słowo pokraka... jak Magpul i pokraka to trzema pokazać to

1. To jest wątek o Magpulu

2. To jest dział o broni palnej.
