So, Magpul has come out with a Personal Defense Weapon, chambered in 556 and taking standard AR mags.
Here is the PDF:

Now here is where it gets fun:
The over all length with a 10.5" barrel is 18 inches and with a 12.5" barrel it is 20 inches. SO, that means, in order for this weapon to NOT be a SBR, (min overall length of 26 inches) it will have to have an 18.5" barrel.
If you want a SBR, that’s cool, but for those of us who either don’t want to do the paper work, or live in a Non-SBR state:
You can have a 556 weapon, with the INCREASED range and terminal effectiveness/fragmentation that the extra velocity from an 18.5" barrel, AND have an overall length of 26 INCHES.
Holy crap.
It gets better… Suppressors become quieter as barrel length increases due to the increased amount of powder burned inside the barrel, AND there will be less wear inside the suppressor.
It would be nice to have a Suppressed weapon, with an 18.5" barrel, that is SHORTER than an unsuppressed M4 with the stock collapsed.
PLUS, according to the PDF the mag release is right next to the trigger, NOT back next to the mag itself, (but there is a secondary mag release there also).
This is definitely something I am gonna buy. If they make it with an 18.5" barrel, so I don’t have to SBR it.
