In this video Stan hops out from behind the camera to show us how easy it is to swap out your AR-15 upper to allow you to shoot multiple calibers from the same upper. Calibers in this video: 22LR, 5.56NATO, 300 Blackout, and 7.62×39.

I have a M&P 15 Sport 2 Lower receiver… I’m guessing I can use any upper on that lower receiver right ?
I am a bit confused. A couple of local gun shops says for the use of any 223/556 lower is only to be used with 223 or 556, not for any other upper calibers such as 300 aac or 22 or 7 63×39. They claim you must have a lower marked as a multi caliber.
I called Brownells and Midwest and spoke to their gun smiths and they claimed that any mil spec 223/556 marked receivers are totally compatable. I couldn't understand how either marked receivers would be different as far as changing uppers. Isn't a receiver just like any other mil spec receiver. The receiver only contains the trigger mechanism, buffer group, and safety and plays no roll in the cartridge itself.
What's up with that?
What complete uppers were the 22LR and 7.62×39?
Is there a company that sell a complete upper in .22 Lr with the proper BCG and magazines? IF there is a company that sells all of the needed stuff together would it be better to go with the complete upper or just buy a dedicated AR in .22 Lr like the S&W AR-15-22 or is that a S&W AR-22?
Where did you get those .22 magazines ?
Why is this guy shooting without the stock at his shoulder? Does he not know how to shoot?
What 7.62×39 upper are you guys using?
They guy shooting has no idea what he’s doing, but speaker performed well
I really enjoyed the video. Would the standard 5.56 lower work with a .308 and 6.5 Creedmoor? Also, where may I find the different inserts for my 5.56 magazine?
Thanks for this video. This explained everything i needed to know. I was wondering if looking for what upper to get, if they had to match the lower. But u explained it all. Great video too
Then Stan dropped the BCG😂😂😂
Mutual of Omaha's Wild Kingdom!
amazing!!!!
Drop with it Larry
Just be careful mixing and matching barrels and ammo. You do NOT want to shoot a 300 blackout in a 5.56 barrel, your gun will explode.
My ar15 stands for Anderson upper rock river lower
Interchangeable is my favorite topic
What lower is this ???????????

Great video, is the shooter intentionally not shouldering these guns because they are technically pistols? The laws are very confusing
I have a AR-15 rifle with a.300 Blackout 16 Inch upper, I want to get a short barrel pistol AR .223 Wylde 7.5in upper for cheaper training sessions. Would I be able to do it ?
So wandering I’m thinking of buying an AR-10 and been comparing between the two. I’ve heard that converting an AR-15 to .308 is very difficult and makes the AR-10 more versatile for changing yo different calibers. This will be my first rifle as I’ve got my handgun and shotgun already. I just want a rifle now.
I'm relatively new to ARs and just bought myself a 556 upper. I didn't know changing out the uppers would be so simple so thanks for the tutorial!

What lower is that? He gave no details (brand or cal) on the Lower that accepts 7.62 & 5.56.
What specific Lower Receiver is that?
Is he scared of that charging handle? Rip that damn thing. Its not woman.
Very cool video, but your assistant seems to be lacking…. Well…. Expirence. I'm sure he's extremely smart when it comes to firearms but damn, he doesn't do the greatest job at conveying such.
Joe, I loved the subject, great info, well presented. If your target audience is YouTube you really need to record in landscape. Portrait is good for Tik-Tok.
Informative and well done presentation.
You should do this with a polymer lower on all these calibers along with 458 socom, 350 legend 450 bushmaster and 12.7×42
You can buy the bravo 22 lr conversion kit by bravo and just swap out the bcg and never change the upper.
I'm no expert but the handler is camera shy or gun newby.
I just put a video out on how my cobalt kinetics doesn't fit my other uppers
Could you get a 308 upper ?
This video is very helpful! Just got my first multi caliber lower and my first 556 upper!
16" 5.56 with .22 insert, 300 Blackout, 7.62 x 39. In my war bag.
Be sure to mark 300 Blackout and keep 5.56 and 300 ammo separate
he kinda looks like Stoner!
so if i get one 556 lower machine gun what happens with a 22lr upper?
What trigger and hammer do you recommend?
Interesting weapon handling…
Very help ful. I am a newbie and shopping for an AR lower and upper! So you can just connect an upper like 556 to a multi caliber lower and make no changes to the lower and you can run with it with it
