Most Helpful Positive Review Sweet Addition to my AR-15
This upper is sweet!! I highly recommend - it was the accessory I didn't know I was missing. Having the ability to switch out my 5.56/.223 upper with a .410 is great. It comes with everything you need, you literally just switch out your upper, insert the .410 mag (comes with two!) and start shooting...

Most Helpful Negative Review Sketchy chamber!
Finally got out to the range with this .410 upper. Would not cycle reliably. Multiple extraction failures and when you look at the spent shells, the brass has a huge bulge in it. Upon examination, the shell is not fully supported by the chamber and allows the brass to deform into the extractor cut o...

Wish I could feed the beast!

by Jack, Verified Owner from MT, United States Written on March 7, 2023
If only it came as advertised, then I would have magazines to feed it. Looks sick, on the wall or in a safe, that's all it's good for. Place a backorder, they may have mags made by the time they're available... or not, good luck!
Pros:
  • It comes in black
Cons:
  • That's about it
Best Used for:
  • Telling your friends you have one that almost works.
Would recommend: No

On the fence

by J, from TX, United States Written on February 23, 2023
The kit came with everything needed to swap the upper and get after it. However, after making a significant investment in home defense rounds, Winchester 2.5” .000 buckshot, THEY WONT LOAD IN THE MAGAZINE, that was provided by spearhead. Not supper excited about that. Hopefully I can find a magpul replacement.

This is a great addition to my AR15

by MRZ, from ID, United States Written on June 15, 2022
I took the new upper out to the desert and tested it with great results. I'm getting another one for my son.
This is a great addition to my AR15. It's like a survival rifle combo with high-quality components. I mounted my QD 65 MOA circle red dot site from my.223 Wylde upper and chose the circle without the dot (purposely did not change zero though)...it made a perfect shotgun option and the pattern hit where the circle showed as I fired from 5 meters making this a great home-defense setup as well as a small game gun.
It resides in a Pelican box with my AR.
Pros:
  • well made
  • All accessories AR specs
Cons:
  • None
Best Used for:
  • fun

This upper is amazing.

by EM, from VA, United States Written on June 7, 2022
Perfect fit on any lower I have tested it on. I have run several hundred rounds through it so far and not one hiccup. This configuration is versatile for every need. Great for home defense and for small game hunting. Looking forward to other products these guys come out with.

Awesome product!

by KP, from IL, United States Written on October 27, 2021
I always loved unique and versatile firearms. This upper definitely fits this category. within a few seconds, if you have an AR15, disconnect the 2 pins, replace the AR15 upper with this one, and you're all set! no need to buy or build a different lower. if you're on a budget, this product will save you the need for a lower. Already have a favorite lower setup with an awesome trigger/stock/grip that you love? use them with this upper! own an AR15 and need to switch it up to a small game hunting/pest control? 10 seconds and you are ready, with a .410 cal to do the job. the product works great. the build quality is good. had no issues with or jams so far. The product is great!
Pros:
  • Quality & Functionality
  • Cost & Features
Cons:
  • None
Best Used for:
  • Small game, Varmints and plinking
