Make sure you label your 5.56 and your 300 blackout magazines and keep them separate with their AR. You can buy stickers off of eBay to label your rifles and magazines and they look great.

Is this similar to the 16ga in a 12ga debacle?

Or, like I do for my 6.8 vs. 5.56, use different types. Since I only have metal mags for 6.8, that makes it very easy. I won’t use anything but Magpul when I have the option, so that’s what all my 5.56 mags are.

Great Idea. As long as I’m not mixing weapons on the range, I have my magazine ammo cans marked. I also try to reload the mags after range day.

It isn’t as much me that I am worried about but the people who I take shooting with me. I have my own personal range. I often let friends and family shoot with me. I never have one of my 5.56 AR out at the same time as I have one of my 300BO ones out. Since more then one person has a weapon out we m…

Anytime that I build a 300BO for a friend I always label a few mags for them and tell them about Ranger plates. I also always get a dust cover showing 300BO as a safety feature for them and their family. It is cheap and easy to do. [20210417_173400]

My 300 blackout is my only FDE gun and it only uses Lancer 300 blackout mags which just so happen to have the FDE floorplates that match to the gun. Everything else I have that shoots 5.56 uses USGI or PMAGS. That way I can’t mix up the mags and I can’t mix up the colors!

Awesome! I’m a poor man and use hex magazines and P-mags. lol

I keep my 300 blackout mags fde or white and 5.56 black

I have seen several people do this and also have the dust covers show the caliber (like on the DB rifle series)
