These bags are heavy duty shoulder bags originally designed to carry 300 rounds of linked 7.62 NATO ammo. They are extremely heavy duty, with a really nice shoulder strap that has a quick release.
These are great for carrying ammo to the range, lots of AR magazines, for walking around the gun show and tossing in stuff you buy- and unlike most shoulder bags they won't sag or rip when you toss in a few hundred rounds of .45 ammo.
The sling/strap is very heavy duty and nicely made, and is nicer than meany rifle slings that cost more than these bags are selling for with the strap.
Made in the USA, real military issue.
