PDW builds - Lets see them, and share results

One can be say 300 Whisper is kind of pointless when surplus 7.62x39 cost about 15 cents a round without the pain of collecting, cleaning, sizing and reloading :p

However I just notice on Robinson Arms' website, they now have a listing for 7.5" & 10 barrels in .300-221 cartridge for the XCR Micro :)

This is just it for me. Practicality of availability. Plus, todays 300 Whisper may be tommorow's 6.8 spc. I love the shortie Ar platform, I just feel it's not well suited to the 5.56/.223 round, in the big picture. Some of you have done some beautiful work, and some of you need to have a beer and shake hands. There are no new ideas, someone has already thought of it, they just may not have documented as well. As for intellectual property, doesn't exist, just ask the chinese.;)

The .300 Blackout's lineage has been around for decades. The only thing that was holding this cartridge back was a lack of SAAMI certification and the proprietary nature of the .300 Whisper developed by J.D. Jones.

Now that the .300 Blackout has been SAMMI certified, the firearms industry can use the cartridge without having to pay royalty fees for its useage.

The .300 Blackout is arguably far more versatile than what the 6.8 SPC is or could offer. With the amount of momentum and industry support behind the cartridge, one could only hope it doesn't end up the debacle that the 6.8 SPS is.

I am surprised to hear it's been around for so long... sadly, business politics have a huge effect on innovation.
 
Let's talk about some performance figures for the 300 Whisper in a comparable bullet to the 7.62x39.

I don't want to discount the 300Whisper because I personally think it's a cool round but 'what if' you could buy 10rnd mags that would accommodate
7.62x39 with a new drop-in bolt face and barrel. Would it be something you guys would consider. I think the only reason the 7.62x39 round doesn't work well in the AR mags is because of it's tapered casing. So now if the chamber was cut so that the casing blew out a bit and worked in AR mags, would this be something worth having?? Also, with a newly resized batch of casings, you could reload with whatever 30cal bullet you wanted as long as the twist rate of your barrel suited the weight of the bullet.
 
Here's a youtube video of Tom Hines shooting a 330 yard 18x18 steel plate with the 7" Diablo upper by PWS using Wolf 75gr ammo.

When you live in the "Land of IF" then anything is possible. When you take into consideration everything you've just said, you no longer have a 7.62x39mm but yet another wildcat round. You're re-imagining the cartridge for something it is not.

Impressive shooting!

Did you really think it was impressive? It didn't appear all that accurate to me. The scope on the PWS was completely over the top as well. Nobody buys a PDW and sticks a scope on it like that. What was the point in doing so then?

So, the rifle can hit a target 300 yds., so what? Did anyone believe the bullet was just going to fall from the sky after 200 yds.? :p

I agree, the scope is a little over the top for a PDW. IMO the impressive part is you can still be confident in your rifle in close and up to 340 yards using readily available .223. There are a lot of combination optics to use or not on a PDW.
 
I had never seen a quad rail the clamps on. Aside from looking a little on the cheap side, I guess it really doesn't need to do much besides protect the barrel and gas system.

Is the barrel centered in the quad rail?
