This is why all my guns are color coded with bands around mags. For example, my JAKL:

For me its 300 blk in plastic mags only, aluminum for 5.56.
I have 2 ars in 300, one has my thermal living on it, the other is a 8.3 inch. I typically only bring one caliber to the range at a time, but I actually just realized that when reading this thread. |

I don’t think having unique mags hurts, but having the wrong round in a can full of loose rounds definitely hurts.

Due to the physical characteristics of the 5.56 and .300BLK rounds and the distinct possibility of an accident with destruction of the 5.56 rifle and possible personal injury, I think you'd have to be nuts to have both calibers at the same time.

Quote HistoryOriginally Posted By DVCER: I don’t think having unique mags hurts, but having the wrong round in a can full of loose rounds definitely hurts. I can see this being a distinct possibility for me. For non-precision rounds like 9mm, 300 Blackout subs, 7.62x39, and a few others, I dump bulk rounds into .30 caliber ammo cans so I don’t have to monkey with 20 or 50 round boxes while loading and shooting. However, I could see inadvertently dumping a handful of cartridges in the wrong can by accident. Thanks for mentioning this, DVCER. |

Wrong ammo in a can usually happens when you take someone else shooting with you, and they don’t know the difference.
Happened all the damned time when running handgun classes, where the agency or academy supplies ammo and has people clear out mags and weapons at the end of the day, then the first ammo loaded the next day came out of those loose ammo cans. Of course a 9mm fired in a .40 won’t blow up your gun, and a .40 just clogs up a 9mm action real well. .300 BLK just needs some extra safety measures in place. Personally I just do subsonic anyhow, and that won’t be causing the issue. Parts commonality is worth the headache. Life has always been difficult when people make mistakes, or are just plain stupid. You want 100% safe? Stay away from firearms… |

DSG used to sell blaze orange D&H mags. Those became my .300blk mags. I since added some .300 pmags, but I wrap the bottoms with blaze orange duct tape to keep consistent. Then my .300 uppers get a blaze orange index clip somewhere along the rail for ID. I see blaze orange and I know to be careful with what I'm doing.

In the meantime, there are clear Lancers, ETS, & 2nd Amendment mags that allow the Eldest Son to be seen. The reason I like bands vs clear mags is that others know also. I don't let folks shoot my guns without me there, but eventually my stuff will be transferred to one of my kids. Hopefully that is not in an emergency type situation but instead a chance that I can sit down and show. But just in case that is where the bands come in handy IMO. |

Found this chunk of receiver at the range a couple weeks back. I have a suspicion of what may have caused it but no other pieces were found at the scene to confirm if 300BO claimed this rifle.
