I saw a pic of an AR with what looked a silicone band marking its PMAG as "subsonic .300BLK". I thought that was a neat idea.

Right now I typically use black pmags for .223 and OD green for 300BLK. But I can't tell if a loaded mag is 115gr supers or 220gr subsonic.

It also would be nice to tell the difference from 77gr match reloads vs the cheapo 55 gr plinking loads. Right now I tend to only use match in the shorter 10/20 rounders as they work better off a bench rest.

Silicone bands seem like a good idea, but then maybe there's something I'm not thinking through- like they won't fit into my High Speed Gear Taco mag pouches, etc.

I'd like to tap into some knowledge out there as I don't shoot AR's on the range nearly as much as I'd like to be, so I'm a little rusty.

I've got ranger plates on 300blk mags so I can tell at a glance.
Just because you are unique doesn't make you useful.

I’m hoping Magpul will come out with .300 blackout TMags.

Or just use paint pens unless you're wanting a less permanent solution.

I just use different colors of duct tape around the bases to differentiate between loads, bullet weight, etc.

That's all 5.56 though.

Were I to differentiate between 5.56 & .300BO, I'd go alot further, to include some kind of physical, tactile difference, for obvious reasons (do NOT want to be mixing those up).

I do two things.
I have a bunch of Lancer 30rnd mags that I've only put .300 Blks in.

But then, I bought a bunch of these...
Some are clearly marked 5.56 some are .300 Blk and some say Subsonic...
Rarely do I shoot .300 Blks that are Supers though, so Subs is kind of a given.

Amazon Product

I use the bracelet-like rubber bands for a visual and tactile difference. Just search "mag band" on amazon as others have pointed out above.

I ONLY use them to distinguish .300 blackout from 5.56.

Blackout is banded. 5.56 is not.

My brother uses different colored electrical tape.
Blue for 223.
Red for 300
It's cheap and works.

I bought the 300blk Pmags, and the Die Free Co. FDE das boot +2 magazine extensions. They're the only magazines that have that type extension on them so they stand apart from the rest of my AR mags

I also use the bands.  I only use them on the blackout mags though, so it’s easy for me to distinguish between them and 5.56.  I also have been buying random mags with designs on them for the Badger.  Because the Badger don’t give a sh*t!  😂

I laser engraved my pmahs with a camo pattern similar to the rifle for my 75gr speer self defense. And so on for my 300 blk...

As far as paint pens, which is better than the other, I bought Markal 96882 Paint-Riter+ and Sharpie Oil-Based Paint Markers

Waiting for them to arrive.

Curious what markers others use and like.

Markal way better than Sharpie
