9mm comment aged poorly haha. Full auto suppressed sounded like a laser gun
I swear your mic is the only one that comes close to demonstrating how loud guns are
Did you modify the bcg or did it run factory FA?
my ears hurt!
What kind of Brace is that. Love the design
A 5" barrel and 4" handguard is just absurdly short IMO. I wear size 3XL gloves and I couldn't even get a hold on a handguard that small. Would have to hold the magwell so I don't potentially shoot my fingers off. Even for people with normal sized hands, that handguard/barrel is too short. I know that have an 8" one, thats much more practical IMO.
Mags are shit
Binary lower?
So I'm not as knowledgeable on these conversions, so if I am understanding this correctly, If I have a standard 5.56 lower, I can add this 5.7×28 upper conversion to it and shoot my 5.7 with those 5.7 mags and use a 5.56 suppressor on it (with tax stamp). Also, I can still put my 5.56 upper back on and fire 5.56 with the 5.56 suppressor too? Do I need to change the buffer when you swap out between calibers? This sounds like a win-win. Sorry if this is all obvious. I just have a few handguns and no AR styled rifles, just cheap soviet surplus stuff so far. Thanks,
Is that the 200 mk57 or the 300 mk57 upper?
Should we suppress it anyway?
Yes the answer is always yes
I saw a video, that 5" can reach up to 500yds, pretty cool
Can you use FN mags?
Which is better overall – this upper or Rattler? With short can, binary trigger and side-folding brace.
Any gas to the face suppressed? Are you using a standard carbine buffer setup?
LOL, It literally sounds like pew pew pew
I’m so glad I saw this video. The full-auto action just made me a buyer. I was skeptical if it would work with my Echo 2 trigger. This upper with a mvb micro buffer will make this a great backpack/car gun.
Can you add a mussle brake?
Sorry, I would rather have an AR57 if I want to shoot 5.7. I hope 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?
Remember the gun noises we'd make as kids? Ptchooo ptchooo ptchooo. That is how the suppressed 5.7 do.
How can I get that lower?! 🤪😂😅
No eye pro smh
Sir, thanks for your time putting the video together.
Recently been looking into the gen 2 echo trigger and wondering if the included BCG would function. Would love to hear your thoughts seeing as you were firing “full auto”. Thanks!
So will any 5.56 suppressor work with 5.7? I thought the 5.7 round is slightly larger in diameter than 5.56 no?
Why not 150 rounds heck why not 250 rounds? 🤔😂🙏🏽
What lower do you have on that bad boy? Thanks…Love the Video
Really appreciate your channel – keep up the good work/solid content
I am wondering if the upper on the Banshee is the same? Have on lower for the 40 rnd mags, and another lower for the fn five seven mags.
Ordered an 11 inch upper with one mag, and a 3 pack of 40 round mags around 2 weeks ago. Sight says they are shipping mid February. Going to do a pistol build on a PSA lower with a SBA3 , I have an extra Larue MBT S1 trigger I am dropping in. Wish I had a select fire lower. That is extremely nice.
SGAmmo or TargetSportsUSA has the good pricing on AE TMJ 😀
Shoot that expensive EA ammo up! HEHE
My 9mm ar is this short, actually a little shorter, but yea I am sure that it is heavier. However, it is subsonic most of the time with 115 grain, and all thentime with 147 grain. Do yo think the 5.7 is more quiet than subsonic 9mm?
Ruger. Please come out with an AR-57 that accepts your new handguns magazines 🙏🙏🙏
Cool
Top Job Will!!!
That's a slick little package there.
Finall, straight blowback should have died 40 years ago along with drum brakes
Gotta love the sound of that thing while suppressed.
I like it…Alot 👍
Too boo coo bucks!!!
👍
Dude please wear eye protection, this video is making me cringe for safety reasons
About damn time!
I wont even crack a 300 joke. Just glad you're back. Cheers!
It's nice you can take an existing SBR and slap that upper on it. Come on though. You have to admit the cost of 5.7 rounds is way too expensive.
Okay I thought watching & having a
Guinness would be great with this my first comment then realize your camera man sounds like it could be your wife I think I love her for loving you awesome🍻💘👍
Minute 44 into the video and I have to say I'd like you to try a 16-inch upper looks like it's going to be a pretty badass video🤘🇺🇸🦅🇺🇸🦅🤘
Looking good 😄
Get a folding brace on that thing!
