CMMG 5.7mm Banshee 200 Upper & Conversion Mags

Expensive ammo that's not desirable for home defense. A 10mm is way superior for that purpose and cheaper. Distance then go with the 5.7 but 223/5.56 will be more practical and cheaper!

Those mags 🗑 bullets fly out on it’s own not safe at all

This would be great pre covid ammo prices….

Can you use a law tactical folder with this bolt carrier ??? How loud is that comp ? Also maybe you could do a follow-up with CMMG's 22lr conversion for it.😁
Thank you for another great video !!

did you have problems with the magazines spilling out ammo? mine spew out ammo just sitting on a table without being touched. i have 5 magazines and they all do this. if you push down on the tip of the first round I can get anywhere from 3-20 rounds to shoot out. I dropped one from about 8-12 inches loaded and about 6 shot out. Anyone else? i bought 5 mags and they all do this. I've seen one other video that shows this and I've barely seen anything else. Maybe my experience is uncommon, but for all 5 of the magazines that I got? I feel like we should be hearing a lot more about this. buyer beware and all that.

I shoot my fn 5.7 at 250yards my masterpiece arms in 5.7 at 250 & 300 yards with ease ! 100 yards head shots all day ! I m getting one next month a longer barrel of course

Don’t Kidd yourself or anybody else about ammo , the commies will ban this stuff just as easily as any other caliber. Also There will be ammo shortages in this cal .
The only people who run out of ammo are the ones who didn’t stock up on ammo and reloading components way ahead of time

I’m worried… mine is about to ship and I just watched a video of major magazine issues… and several people in the comment section of said video saying they have the same issues.. failure to feed and rounds just shooting out of the magazine for no reason…. what gives ?

The firearm is great the conversion mags develop issues. I have experienced the same problems as this guy after leaving loaded mags for awhile.

My 5.7 banshee shot fine to sight it in… Then… Coyote in my yard got away because of what cmmg said is a out of spec firing pin 😟 Thank God I wasn't using it for self defense 🙏.

Make that shoulder jiggle!

Overpericed and garbage customer service rather buy a diamonback dbx

Can u slap on any lower on this 5.7 upper? Will it perform the same?

I live in California, can I get this with a 10 round magazine?

Please, CMMG, build one in .22 TCM. Better than 5.7.

This is also available in 7.62×39 with a mutant type bolt face and standard AK mags. If you need to penetrate windshields and car doors.

Where did you find 5.7 ammo, I called around to the shops here in Vegas and it always seems like they don’t have

great video man…nice explanation & articulate. But i would have loved to see some 75-100-150 yd shooting at the end, but that's just me. Cheers mate!

They have ten round mags so you can ship to cali but if it’s not on the hand gun roster the I think it would have to be a sbr ? Idk 😐

What's your thoughts on this over a Masterpiece Arms MPA5700DMG carbine in a 16 inch barrel and folding stock?

One thing that sucks about CMMG.. they use a proprietary cam pin. So it's a bitch to use a side charging upper. I had to have my cam pin specially made. Cmmg was zero fucking help.

Can you use this magazine on a cmmg banshee 5.7?

Now all you need are some black tips

Unless you already own a 5.7 handgun [ and I have only seen 4 or 5 people carrying one in over 10 years ], why bother? The round is comparatively weak, there are so many better options.

I want one 😮

Sexy looking gun

I literally just bought one yesterday, can not wait for this to all b over to go and shoot it!!

There's no need to buy this firearm or any other firearms chambered in this round when there's not enough ammo made in this caliber! Hell, it's way expensive and none to be found!?
I don't even ammo for my Ruger 57???

The sneak governor of Virginia just signed gun control laws into effect and no one knows cause of the pandemic!!!!

1500 rounds of 5.7??? You must be a billionaire

I do run an H2 buffer in my SBR and Pistol AR lower, and occasionally subs would fail to lock back on last round, but otherwise they ran fine. Probably would LRBHO with a lighter buffer, but the tuning weights don't seem necessary.

Not only is that bolt spring-loaded, but the back of the locking lugs are chamfered to force the bolt to rotate before moving backwards. That's what causes the delay and why it's called RADIAL delayed blow-back.( RDB)

Is that the range near cold creek?

Shorts barrels are sexy

This is literally my dream home defense gun that I didn’t know existed

Short recoil, snappy bolt action…..great truck gun!

I went to my gun range yesterday and look at some cmmg I thought they were junk AR man I got fooled I got to get me 2-3 of them

I hope we all come out realizing that the whole fixed mag or 10 rounds is a huge issue and needs to be dealt with for our own safety

Badass 🤘🏼

I’m definitely getting one of these after I see some more positive reviews. It will pair nicely with my Dead Air Mask HD that is rated for 5.7.

Very expensive way to have an underpowered ar15. I had a 5.7 with the FNP 50 rd mag. Not a fan. I built an AR15 in 22TCM. 2800fps for a 40gr out of a 16 inch barrel. I can make ammo from 223 brass.
