Great ammo, no issues. Solid 5.56 rounds from ZSR. Great for target shooting.

Ran about 120 rounds through my smith and Wesson AR15 pistol and AR rifle and rounds ran through fine no jams. I noticed significant more fire out of the barrel compared to shooting my other rounds. Good price no issues.

Shot 120 rounds ran flawlessly

Shot 30rds of this stuff and had zero issues.

This is a great deal and it runs flawless through 3 of my AR's that I've tried it in.

Took a chance on this, since it did not have any reviews. Tested in a firearm, that was clean, lubed and has cycled all the .223 Russian steel it has been fed, flawlessly. Thought I might get some better accuracy from this 5.56 brass cartridge, without having to buy a whole case... No better accuracy and had two failure-to-chambers, out of 30. I will test again next session but if I have any more failures; out it goes and I'll be stuck with 10 boxes... Decent price, initially but not a good value, so far. I will not be buying this again. Update: Cleaned firearm, shot another box of this and had two failure to chambers, which jammed in the chamber, just like the first failures; crimping the cases, making them very difficult to extract. Shot a magazine of .223 Wolf steel, immediately after and it cycled flawlessly, like it always does. Definitely will not buy this again.

Its shoots well. Rounds were not crimped very well and had one that failed to fire. the bullet squibed in the throat when I extracted the round due to how terrible the crimp was.

Looks like run of the mill 5.56

Excellent bulk ammo. No issues with cycling. Good product
