You can now shoot the incredible 5.7x28mm round using your AR15 lower. Just add our AR Conversion magazine and one of our Radial Delayed Blowback uppers and you’re ready to go! We even have bolt/barrel combos for builders.

A little on the high side , upper should be lower than $500
Any plans for making a more compact 20 round mag?
Until all the rounds shoot out of the magazine due to poor design and QC. New mags on the way… let’s see if they suck or not. I have my doubts because this issue was known a full 2 months before I got mine and I was assured it was fixed…. yet It is still happening.
How much did that magazine cost to design? If it wasn't too much, think of this: 30 carbine.
I was told its a felon charge if i put my lower ar on my 5.7 upper?
Over priced
Standard bcg?
Just shot the pistol version today and now I want one! Can't decide between the complete package, or this kit……
Sorry, I would rather have an AR57, and I hope you, or someone acquires it. 50 round mags are the best mags. Now with pistol braces and the AR57 pistol upper, I think it's time has come and no one is producing it.
I wondered if shooting the AR57 would be hearing safe as it ejects down? It is full ambi. Did I say 50 round mags?
Ffuuuuccckkkk I love you guys so much.
What buffer weight is recommended?
could you make it in 17 hmr or 17 wsm??
Just want to say I really appreciate what this company is doing for the AR market.
I can have the same gun, and now I can change it out to shoot multiple calibers. Very innovative and impressive!
PS. Best customer service ever
Anybody else here and subbed because Johnny B sent them?
Wow , splendid gotta get one of those if i manage to get in our law enforcement , gotta love clearing rooms with that small barrel
We need this in 9mm and 45acp.
When in Canada?
The 10 round may that is getting released, is that going to be shorter? Or is it just going to be a pinned full length magazine?
Can the barrel and bolt be used in a standard upper?
Worthless crap
You have my attention!
WOW is that all I need?? $2 grand worth of rifle stuff to shoot a pistol cartridge.
So it's full auto?
5.7 picking up steam
Shut up and take my money! The only thing to be improved is a 50 round mag instead of a 40 round one.
I’ve no shit been waiting for just this type of product to come out! Nice.
I'm sold
damn, imagine a 5.7 with that sexy 16 incher
