Top quality Blackhawk branded ammo cans. I'll be purchasing more in the future. You can NEVER have too many ammo cans!
Already filled the cans up with .223 and .40S&W.

Metal cans for sure. Lids seemed a bit warped at first, but pretty much worked out the fit with opening and closing a couple of times. A very tight top fit, which is what you want. They got a 4 cause I felt they were on the line between mil spec 1 & 2. I will buy the brand again because my other purchases from this brand have had no problems. And you can't silly because you got a tight fitting lid seal.

These cans arrived in a timely manner but I could immediately tell these were not "new" cans. The hinge on the one is oxidized and corrosion starting. It appears like the cans were re-painted and in a rushed horrible fashion with big globs of paint in multiple areas. There are scratches all over the cans with some paint scrapped off in spots. The seals are really what gave away that these were likely refurbished cans. The seals had the typical white crusty look with cracking dry rot that you find in used army surplus cans at the local outdoor stores. The only reason I originally bought these, considering the higher than average price, was because I was expecting a new quality product, not a refurbished one. Save your money, I will be returning these. The cans that arrived were in a box from solid tactical, so I left the same review on their listing.

Cans are new and are come in the typical olive green color as pictured. They seal tight, which I love. When they lock down, there is no question that the cans are sealed. They feel durable,

Just a though for those who will add the lock unit sold by another manufacturer on Amazon, this is not a knock against either manufacturer, On the 50-cal can, I had to use a dremel to open the hole on the latching flap a bit more as the tolerance was too tight for the bolt to fit through. I would prefer to not have to put a lock on the cans, but kids can get get curious and I'm locking up the ammo to add a measure of safety.

The cans arrived with no issues. The only thing worth mentioning is that the cans smell from the paint. The paint was done evenly. No drips along the side or blemishes. It's definitely stronger than the plastic ones I have. Not that I'm going to be lugging bullets all over the place. The small can takes boxes of 40 caliber perfectly. The bigger will handle 9mm. Maybe I'll try mixing them up in the big can to see what pattern of boxes maximizes the amount of boxes I can fit in. I thought I had more boxes of 9mm rounds so I have to buy some more to try it out.
Expensive for ammo cans but worth it when comparing sturdiness to the plastic boxes.
