this should be a give away with a maxim CQB PDW brace
That looks great, how can I find the best lower for the cmmg mk57 upper
Is this gun an sbr ?
Kind of a dumb question maybe, but can i use my 5.56 can on that 5.7 upper without baffle strikes? Thanks in advance.
Came here to watch a video on a banshee.
Leaving being sold on an echo trigger.
Cant support cmmg they need better customer service
Cmmg hit it out of the park with their radial delayed blowback.
Nice.
..
How much?You're already out of stock…
I love how they advertise it, but only carry a dozen @ best..
What! $750….. just for a complete upper and 3 mags..?
CMMG must be on crack, I rather go the long haul and get the original 5.7… a PS90
How much
Thinking about
PS90 and done. This is useless as tits on a bull.
That's cool!!!! I want one for each hand! With full auto option of course! And suppressed!!!!😁 Hey maybe throw in that one with the BMG for a ankle backup.😀
YouTube doesn't like guns disassembled on video
>Sad ForgottenWeapons noises<
Rather a use a "pistol" AR loaded with Green tips.
Cool but grossly overpriced
We can't get the "good" ammo so meh…
Cmmg is one company I will never do business with until they learn to be reasonable on the pricing…
This is really the dumbest thing you can buy. A more expensive under performing round than 5.56
Get rid the buffer tube slap some under arm slings on and akimbo up chuck norris style
Unmitigated Junk
I'd buy one if it had a longer barrel. Like 10.5" , you lose too much velocity out of a 4"-5" barrel.
This will go great with my Ruger
They’re all sold out 😿
Awesome. If the cost of ammo would come down I'd buy one. But until then nope. I like to shoot mine.
Wanting an ar15 gun that shoots a 5.7 it's like saying I want to pay rent to have a smaller penis
I cant wait to purchase!!
Looks funky
I think for the price, just buy a ps90 and get 50 rounds and pretend your at stargate command
Cool, but why?
Hey, I’d really like to change from a larger, more powerful less expensive, more common caliber to smaller, more expensive, less powerful, less common one.
???????????
22LR conversion makes sense but this is just… dumb. Cool, but dumb.
Sorry man, but it's crazy to spend the price of a fully completed AR just so I can shoot extremely expensive ammo that I'll prolly never have a real need for. This is a product without a market
Your hand gets pretty close to the end of that barrel….
Until i win a give a way gun i wont believe you guys actually give them away😉🤞
What is wrong with the mag insertion that you have to hit on the bottom of the mag?
57center has been making a 5.7mm AR upper for quite some time now. I've owned an upper from them for years. 6" barrel, 50 round FN P90 mag, side charger. Top loading and brass ejects out the magwell so you can use a hollowed out mag to catch the brass. Loads of fun. But ammo is not popular and thus not cheap. It's one of my favorite firearms though.
5.7 is better than .223 for pdw work – less recoil, decent armor penetration, light weight (read better ability to carry), and who cares about the lack of range? Plinking is great fun and the lack of gas impingement means no worries about bringing the barrel under 9".
About the only downsides of this compared to a similar 9mm for plinking are the lack of ability to shoot at many indoor ranges nor shoot at steel due to its higher velocity and its higher expense.
