Best AR 15 Add-On You Can Buy
This really is the coolest add-on you can buy if you have an AR15. You don't need to do anything. You just switch the uppers. The 5.7 magazine sits on top of the upper, so no adjustment to the lower on your AR. In 30 seconds, you can go back and forth with two different calibers on your AR. The cartridge ejects through the mag well. Well built and looks super sleek! Highly recommended!

ULT AR57 UPPER
Bought this and an put it on a Aero Precision Lower and it functioned fine. I recently fired it for the first time and it cycled pretty well putting 150 rounds through it, 2 jams out of 150 that cleared right away using American Eagle 5.7 range ammo and genuine FN Mags. Haven’t fired genuine FN am...

Expect Jams
I think this company sent out of business because they couldn’t get it to cycle correctly , I believe these are all old stock. Good luck getting any support, you’re better off reading the forums. Do not use the buffer that is included and instead order a 9mm heavy buffer, around 7oz. Oil it and shoo...

Ran Through 500 Rds Flawlessly
I had this upper fixed onto a cheap Anderson arms lower for around a month marinating in clp before I was able to take it out to the range. The anticipation was killing me from the mixed reviews here, with even some of the positive ones claiming jams. Had a blast plinking steel from 75 yards. 500 rounds later while sighting in a red dot, it didn't jam a single time. Crazy powder fouling is to be expected but honestly just makes cleaning that much more satisfying. All in all, I'm more than happy with my order and will definitely be recommending this upper.
Pros:
- Fun
- Capacity, Color, Quality
- Interesting concept
- Reliability and ease of use
- Comes with buffer
Cons:
- Expensive ammo
- Barrel shroud not removable
Best Used for:
- Target shooting
Would recommend: Yes

AR57 5.7mm x 28mm pistol round in a rifle
I've been wanting to get a small caliber neusance animal in a compact rifle. I looked at this one several times and read many reviews! Decided t I buy one try it out! I also bought flip-up iron sights. Mounted it on upper and a lower! 3 of us shot it straight out box no adkmjustments hitting rmtarget groups very effectively! One son shoots left-handed. Same results, very accurate at 60' standing! Loved it so much, Bought 2nd one and some 50 round magazines. Worth the price!
Pros:
- Easy to mount to lower! Acquire targets!
Cons:
- Hard to load mags. And, ammo is high priced!
- Harder to load mags. And, ammo is too, high priced!
Best Used for:
- Fast, short range, predators, target practice.
Would recommend: Yes
Can find it cheaper with a Mag
Looking around you can buy the same upper with a magazine for a little cheaper at Palmetto State Armory. With that being said upper functions great and would recommend it.
Pros:
- works with FN mags
Cons:
- cant get an empty AR mag in the mag well to collect brass
Would recommend: Yes
No clip/magazine
Ad clearly shows the magazine mounted on the unit. After receiving the unit i had to scour the ad looking for the lack of a magazine. So hopefully you will see this. I haven’t shot it yet… guess why.. seems pricey for an upper
Would recommend: No

Didn’t work.
Took to the range, it would never fire. It would load from magazine but firing pin isn’t hitting the primer. I believe it’s not going in to the extractor correctly. Looks cool. Wish mine would function.
Pros:
- Looks cool
Cons:
- None
Would recommend: No
