How successful will this be and will the 5.56x30 come back as a viable pdw cartridge?

>How successful will this be
lol
>will the 5.56x30 come back as a viable pdw cartridge?
Come back? Was it ever here?
>viable pdw cartridge
I don't see why not, it does what everyone wants, less available than 5.56, less effective, but at least it'll be more expensive! The best part is there's an even better, more established cartridge for the role that is dramatically more useful thanks to its presence in pistols and PDWs with a superior magazine capacity.
I'm sure this roaring success will sell at least one gun if they ever actually put it into production. Anyway tell whoever made the product listing to delete this cringe shit and write something less retarded, also fix your spelling errors you stupid shit.

They're literally hand making these by cutting up and rewelding AR-15 parts. I really want to shit on how retarded this project is but I think (hope) they know it's retarded and are just planning on building these for the handful of people who want them because it's a fun project.

Doubt it, since everyone seems to willfully ignore the fact that .221 Fireball (5.56x35) exists.
>>64832417
5.7x28 is ass.

>5.56 MARS
Doesn't exist, so they can make up whatever they want about its performance.
>vastly better performance
Then why not use 5.56x45?
>uhhh it's compact and light
Nigger come on. if you want a more compact gun....well 5.7 definitely does that better. Better capacity too. And it's a real round that actually exists and has numerous loads with different projectiles for different uses.
Meanwhile you could just get an AR pistol that is just as compact and weighs the same, and will have better performance. It's a concept to be hand made for the two people in the entire world that are into obscure Colt prototypes but also don't really care if it's made by Colt, since you know, Colt collectors buy Colt guns and this isn't being made by Colt.

The MARS 5.56x30 is a cut down 5.56x45 with rifle pressures and near-rifle performance. The jeet 5.56x30 is a knockoff 5.7x28 with even worse performance. They're not even remotely comparable.

.221 Fireball is less than a quarter inch longer than 5.7 FN, and fires a 5gr heavier bullet 600 fps faster out of a 2" shorter barrel. 5.56x30 MARS will be closer to .221 than 5.7.

>>64833075
ok you saved zero weight on the rifle since there are lighter AR's with the same barrel length, magazines are only available in 30 round capacity so you don't get any more, also the round is the same width as 5.56 so not really making any gains at all in terms of capacity even if anyone else makes mags (lol).
>improve your combat loads
it fits in AR-15 pouches so no, same combat load.
>and weight
Same projectile weight as 5.56, so again, no. That's where the weight really is in a cartridge.
You are getting worse performance and zero actual benefit.

Ok that's great. So why not use 5.56 if performance is what matters and not being compact and light?
>uh because the perfect middleground is a gun that weighs the same as an AR, is as big as an AR, but is less effective than an AR
Somehow I doubt it.

fake answer:
>the awesome performance of the meme round that doesn't exist and never will go into real production
real answer:
>they're hand making these by cutting up AR parts and welding them back together, this is clearly a project with zero practical value done because it is someone's autistic fixation and they're willing to sell it if anyone wants to buy it
>since it's hand done and a max of like two people want this it doesn't really hurt to offer it for sale since they don't have to waste time stocking product it can be done to order
>>
>>64833091
Wow you convinced me, you buy this gun with your money then. Go spend $3000 on a copy of a failed prototype made of cut up and welded together parts that may or may not work, and go buy ammo that doesn't exist for it. Enjoy the two magazines that come with the gun because they are the only ones you will ever get.

>>64833101
Oh no, my problem is entirely that it is utterly pointless and offers zero advantage over any existing cartridge or rifle, and numerous disadvantages.
It is a shit idea and you're a retarded faggot. Now fix your spelling errors in the product description, shill.

>uhm it's so much better than 5.7!
Oh, then why not use 5.56 instead?
>uh because I don't care about performance!
Then why not use 5.7? You'd get more capacity and actually be able to buy ammo. And an actually more compact gun.
>nooo I need better performance!
Then use 5.56.
>nooo I need this specific handmade gun with ammo that doesn't exist, only two magazines! I can't just get a lighter weight AR, or an AR with a shorter barrel, that would ruin everything!
I have an ever better idea. Let's make 5.56x40. That would really give the best of all worlds.

Its not as compact as 5.7 because its not straight walled and can't be shoved into a 50 round plastic mag that doesn't stick out the bottom.
People have been butthurt for over 25 years over this but the objective fact is that 5.7 succeeded because of the mag. You can deny it however you want but P90 mags are just worth all the problems.
