What do you like about the product?

I ran the first 300 in full auto on a number of different host weapons. My rifles ate all the 5.56 I could give it without stopping. Will be buying more now.

What would you like us to improve?

I mean, maybe the next free gift is a velcro patch with your kick ass logo on it?

Comment

Can't wait to try the 300 BLK now.

What do you like about the product?

I was sent some sample ammo and it shot great at my 100 yard targets. I came home and ordered 1000 rounds. It was delivered in two, 500 round ammo cans along with a hat and sticker in each can. Fast and Free shipping.

What would you like us to improve?

I don't know what you can improve on, just keep offering quality ammo at reasonable prices with FREE shipping.

To everyone out there; it's time to stock up, with all the wars going on around the world, ammo isn't going to get any cheaper.

What do you like about the product?

I like the ammo can and ease of knowing that it will go boom when needed

What would you like us to improve?

Maybe a little better package if would be nice. My sticker was a little crushed when shipped inside the ammo box but it’s not that big of a deal.

Comment

I like the ammo for the price point. I ended up giving it a chance when I saw it was 37 cpr. Went to the range today and shot probably close to 150 rounds thru my ar. Everything went boom and no issues when firing in semi auto and with my binary trigger.
