still wish it was 50 round just for ease of loading
yeah, and i have a feeling im going to finally buy a fire arm with a binary trigger. which is kinda sad cause it is not a cheap round to be doing that with lol
so what we’re looking at is a 1249.99 dollar x57 with binary trigger i bet.
So should I load up on Beef or Chicken Top Ramen?
Shrimp!
2:20 to 3:45. Sounded like they got the designers of the x5.7 to talk about it.
Or like the ruger 45acp pc carbine, that would be dope for suppressed configurations. Would be like HK MP7 at home but legit bussin bussin fr fr
loved the engineers there to talk about the x57… but watching further i loved that he showed us and spoke about the stg44 so that yall can know that it is still coming!!!
I don’t think I’ll be buying a X5.7, but I’d love to have a couple of those 40 round magazines for my Rock. Maybe they will start producing them first.
I’m not sure why you would turn down pure sex, but whatever rocks your socks. I am 100% with you on getting some of those magazines to run in my rocks and a pebble when those come out.
That Pebble sure will be nice and compact with a 40 round magazine threaded barrel and a suppressor. 
Please give us an 8" barrel on the X57…
Amen!
X2 on this!
It feels like the engineers’ main motivation was to bring an MP7 to America, not necessarily to make a rock carbine. Surely we’ll get barrel options though, right?
Whatever the intent, I will be thrilled with this based on everything we’ve seen so far.
the video i saw of them speaking with a youtuber did not give that feeling at all. In fact they were pretty hard core into the 5.7 round itself. and were pretty proud of the interchangability of the Rock’s parts with the x57…
As much as I like 5.7 I don’t the point of the point of the carbine. 
Lightweight low recoil high capacity optimized ballistics…
There are advantages to having a carbine and a pistol in the same cartridge. Besides sharing ammo, if you can share the mag, that’s even better. It’s especially useful for those folks who are wanting to downsize their life or consolidate calibers, etc.
Now, for my part, I have no interest in a 5.7 carbine or shorter barrel PDW in 5.7. My reasoning is that if I’m going to go into a carbine or PDW, I am best served, personally, with a 5.56 (or 300 BLK, but let’s keep it in the same .224 caliber bullets for this discussion). Once I upsize to a carbine, I personally don’t have a ton of advantage in sticking with 5.7. the 5.56 has more range, armor penetration, and ammo options, all at a lower cost, than the 5.7.
For my purposes, the sweet spot for 5.7 is the Duty Size pistol; something with roughly the footprint of a classic 1911 or maybe a G17 and has a 4.5" to 5" barrel. That hits the ballistics for the 5.7 that I want without crossing the threshold in size that makes me want to switch to a 5.56 carbine.
It is absolutely true that a 5.7 has less recoil than 5.56. However, out of an AR carbine, that difference is, frankly negligible. If you can put the butt of an AR into your crotch and pull the trigger without racking yourself (which you can with an AR in 5.56), then, in my opinion, there’s not really my incentive to reducing recoil more.
All that said, a 5.7 PDW or Carbine does have a cool factor and, I admit that I’ve bought guns before just because I thought they were interesting or neat even though they did have wonky and scarce ammo (I’m looking at you two, Astra 400 and Enfield No. 2 Mk 1* revolver!)
Further, I still kinda want a levergun in .45 Colt to pair with my SAA in the same, not because it fills a niche but, well, just 'cuz I want the pair. Maybe someday, I’ll get one.
So, for myself, while I don’t see any “point” to it in my arsenal, I certainly don’t begrudge someone else wanting one. There absolutely are valid reasons. They just don’t apply to me at the moment.

I think you make some perfectly good points here, but once you get a 556 down to the size of the x57 then any ballistic advantage that it used to have is far out the window, It’s just a heavier fireball machine at that point.
One of my favorite things that illustrates that is a video of some guy testing 5.7 versus bulletproof glass. And of course it doesn’t work because we’re talking an inch and a half of polycarbonate maybe more. And then he pulls out his 10.5 in AR-15 and is like “this will cut through it no problem” which it then fails to do and he remarks that the rifle and 556 that he tested this with yesterday did that no problem.
And that is absolutely an issue for 5.56. For me personally, I chose to address this issue by making my AR Pistol in 300 BLK.
