What do you like about the product?

Runs good in my 16” PSA and 14.5” BCM AR-15, no feeding or cycling issues.
Good accuracy—holds about 1.5-2 MOA at 100 yards, consistent for training and drills
Clean enough, doesn’t leave excessive residue like some bulk ammo.
Brass is good (ATS headstamp)

What would you like us to improve?

Would love to see MAGZ similar to what you have for 7.62x39, Maybe offer a bulk pack
A 62gr or steel core option would be great for variety.

Comment

Good value, reliable, accurate enough and clean. Perfect for training, drills, and stockpiling. Definitely recommend if you’re looking for bulk 5.56 that runs smoothly in any AR setup
