What do you like about the product?

The rounds I received were some of the best I've seen recently. Clean, consistent, reliable and accurate.

What would you like us to improve?

Some mark 1 merchandise and gear to proudly wear and use to show my support.

Comment

These guys aren't afraid to unashamedly stand for FREEDOM and that particular way of life and I will continue to use mark 1 as long as they do. The only thing better than the rounds they produce is the customer service they offer. Outstanding job gentlemen and keep up the good work! Stay FREE

Heck yeah, brother!

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.

Mark-1 Team

Thank you for your feedback! We're glad to hear that the ammo performed well for you. We apologize for the inconvenience with the packaging and the sticker – we're constantly working on improving our packaging to ensure everything arrives in perfect condition. Your feedback is valuable to us, and we'll certainly take it into account. We appreciate you giving MARK-1 a shot, and we're thrilled it met your expectations at the range. Stay safe and happy shooting!

What do you like about the product?

Like most folks, I was skeptical of a new brand, but Mark 1 made a great intro offer. I’m pleasantly surprised. After shooting about 100 rounds suppressed (RC2, 11.5” barrel), I found the ammo to be solid range plinking material. Will happily buy again around the same price or slightly higher.

I also found the customer service and the experience to be great — an ammo can, a handwritten thank you card, and a hat on the first order. These folks really seem to care, let’s hope that care and the quality holds up!

What would you like us to improve?

Only availability. Doing great!

Thanks, folks!

What do you like about the product?

I love the product because the ammo shoots so well at a great price!! Super consistent with my shots at 100 Yards. Poa poi for me off a bench. It doesnt shoot very dirty for me, casings eject well!

What would you like us to improve?

The ammo, stickers, and ammo boxes are awesome and i have nothing negative to say. Only a suggestion to maybe have an option in the future where we can buy a box without the ammo if it saves us more money or lets you guys be able to pump out more ammo? Otherwise im going to find myself with a ton of ammo boxes, though thats not a total negative. I just wont have the room for them!

Keep up the awesome work. Your customer service is great, and you move a great product.
