AR question re: switching uppers

[Outbreaker]

Oh wow! I had no idea that many calibers could be used. I also didn’t know all I needed was a new complete up to swap. Thanks for the info

And .204 ruger

6.5 Grendel

6.8 SPC

50 Beowulf

.458 Socom

5.7

9mm

45 acp

277 wolverine

22 Nosler

.22 LR

30 AR



All I can think of for now and all on AR-15

For clarification some of those will require a different bolt and mags.

My recommendation would be to get a complete upper BCG and charge handle and all. It will make swapping quick and easy.

ALSO... make sure you label your mags and uppers cause you don't want to put a 223 through a 300 blackout.

Out of that list mainly 9mm, but From what I’ve read I’d have to have a special mag block or something to do that.

You are correct with all the pistol cartridges.

I just built a 300 for a guy I'm doing a trade with, finished the build, installed it on my AR15 lower and took it to the range today.. that lil 300 blk out cartridge shot so good! I was really impressed with the speed, cycling and impact energy. I'm going to build me one now!
