This rifle is insanely good. Tried variety of bullets and it took it like a champ. Good grip and always good to go.

This is shotgun is very nice, it reminds me of a Remington 870 which is already made into a tactical home security.

This shotgun rocks for the price you can’t beat it, I was really surprised at the smooth action, shoots 3 inch slugs very well handles high brass rounds with no jams. For the money it’s a 10 out of 10.👍🏻👍🏻👍🏻 well done ATI

This seems to be a sturdy little shotgun for the price. I've seen a couple fail reviews where the shells get stuck when sitting multiple times but haven't had that experience.

This is the first firearm I've ever owned, and so far, it's great! I've shot about 50 rounds through it at this point, and the only problem I can think of is that the action will sometimes jam up if I load the magazine full. Very well could be user error as this is the first shotgun I've ever used, but if the problem persists I will update my review. Overall, I couldn't be happier considering the price I paid.

that gun fires real nice and smooth little kick but not bad.

The American Tactical MB3-R is, for me, the first choice of home defense weapon. It easily accepts a CHOAT +2 extension making it a capable six-shooter. The stock and hardware are utility grade, as they should be. The included picatinny rail has been mounted with a simple red/green reflex optic. Smooth action. Very pleased.

Great shotgun for a great price. Wish the loader was longer. I would say use 2 1/2 inch shells to get 4 in the loader.

For the price I was hesitant on purchasing but gave it a chance.
After cleaning the factory lube everywhere I too it to the range.
Good shotgun with no issues. Kicks like a angry mule, slugs are brutal.
Birdshot and buck were flawless.
I would depend on it for home defense and truck gun. Thanks again
Buds!

Buds t ha is as always ! Good little inexpensive gun ! Get you one you won't regret it

Just pick it up today and shot 25 00 buckshot rounds and 25 slugs. Fiber optics front sight fell off. Probably the worst shotgun I've ever shot. 1st shot had a malfunction with trigger would not fire. Until I gave up and threw it on the ground. When I picked it up and the trigger started working again. Barrel has a huge stamp that says made in China. Why 2 two stars? Because it goes boom and it was $150. Would I depend my life on it? No way. Zombie apocalypse happens this one is staying behind..

I am very pleased with my purchase. I wasn't expecting much for the low price I paid but it's actually really decent so far! No malfunctions whatsoever and fun to shoot. I got this for a bedside shotgun but as much fun as it is I'm sure it'll find it's way outside quite a bit! Thanks to Bud's for the great deal, super fast shipping, affordable lifetime warranty and the easy transaction. This was my first time buying a firearm online and certainly not my last.

I have been looking for a really good deal on this type of shotgun, and of course, Bud's is the one who delivered, and in a big way. The gun is from what I see a perfect choice for home defense. I plan to take it out as soon as I can and shoot it with not only my defense rounds, but also some hunting rounds, just to see if it will throw slugs and buckshot with any accuracy, that would let me use it for a thick woods deer gun. The team at Bud's was super fast, with delivery in 3 days, and the interface on their website couldn't be easier. I have bought firearms online before, and they are just about the best as far as making things super simple. I am pretty much finished buying guns for awhile, as I have what I want, but when the need or desire strikes me again, Bud's will be at the top of my list, both because of the ease of ordering, but also a big factor is the free shipping on their firearms, which many online sellers are from 20-50$, which is not insignificant when only trying to spend 160$ on the gun itself. So extra for shipping is a huge deal breaker.

For the price this gun performs very well and I would recommend it.
