Questions & Answers
Is this lake city ammo?

Yes, This is Lake City ammunition. There are two companies that supply from Lake City ammunition plant.
The most common is from Winchester. The other is Remington. Ammo that's 5.56 labeled (NOT .223 LABELED!!) from these two suppliers are LC headstamped.
Please don't use ammo labeled 5.56 in a rifle or barrel that's labeled .223. You may have a great big KABOOM that could endanger your safety, your body, and even someone else that's in close proximity.
Lake City 5.56 cases are stronger than .223 cases.

Helpful Positive Review good product by Nick, Verified Owner, May 8, 2023
Nothing super special shoots and feeds well. Good for the low price. When you order the cheapest you don’t expect perfect ammo but I haven’t had any issues. Wish I had ordered more ammo than I did at the time.

Helpful Positive Review Great for any application by Jamie Chartraw, Verified Owner, February 25, 2023
This is the main ammo I shoot. This ammo shoots really good groups at 150 yards. It’s always dependable and have never had a misfire or failure to eject. It’s nice to be able to know what you are getting with this Winchester ammo.
