I have 2 very similar AR pistols, one is .300 BLK and the other is 5.56.
I am very conscious of loading the wrong caliber in either one, and having a bad day at the range. I ran across a local company (to me) that makes these caliber ID tags.
Helps avoid an ‘oops!’
I am in no way affiliated with this company, I just found their product handy for my needs, and thought someone else might as well.
They are for M-Lok handguards, and are very nicely made aluminum.
Thats a wonderful solution to the wonderful problem of having too many guns to keep track of.
Great idea, easy enough mistake to make.
Similar rounds always scare me.
I’m a .308 fan so for that reason I will NEVER own a gun that only shoots 7.62 NATO
Definitely a good idea. I used etched ejection port covers back when I had an AR chambered in .300 Blackout. Then different colored mags to go with it.
I never liked the etched ejection port covers. Most of the ones I’ve seen looked cheesy.
I never load my mags during a cease fire, First mistake for some unknown reason 5 years ago at the range I did.
5.56 mags on my right 7.62x39 mags on my left, the mags were all 10 rounders second mistake
no marking on the mags and both rifles are in the AR platform. The range was declared Hot
I had the 7.62x39 ar on the table and I was going to continue to shoot, I removed the chamber flag and loaded a mag hit the bolt release flipped the safety off and pull the trigger and I hear puff I thought I had squib. I dropped the mag and realized what happen.
Scary. I’m a little paranoid about that.
Since adding .300BLK to the herd, I have a few rules I abide by.
NEVER load 5.56 mags in the same room as .300BLK.
NEVER take both calibers to the range at the same time.
NO loose bulk ammo of either caliber. It’s too easy to get them mixed up.
All .300 BLK mags are marked with mag bands. I mark subsonics with a second band.
I’m slowly switching over to Gen 3 Pmags in coyote brown for all 5.56 guns. I have about 2 dozen now, and pick them up as a see a decent sale.
