Most Helpful Positive Review Price can't be beat
Fit and finish was what you would expect. No issues. It came packaged nice and was oiled down. Went right on my PSA pistol lower without a problem. Shipping was quick and hastle free as always from opticsplanet.
Most Helpful Negative Review incorrect install
Ordered it. Nice finish. Seemed Nice but the forward assist was installed correctly and the pin was broken had to take it to a gunsmith to have fixed. It's accurate but it conserns me that parts are installed incorrectly from a manufacturers part how many more people had this issue.

Handguard was different than pictured

by Evrev, Verified Owner from MN, United States Written on July 8, 2019
Handguard on what I received was different than the picture listed, it was still mlok same length etc but the one I got extends down below the takedown pin holes instead of being even with the bottom of the lower edge of the upper.. it's completely aesthetic but still very annoying that I got something that looks way different than expected.

Great upper!

This upper surpassed my expectations by miles. It is very well built and functions flawlessly. For the price, you can't beat it. I plan on buying another on 5.56 soon. Thanks to optics planet and radical for being awesome.

Happy customer

by David, from GA, United States Written on October 1, 2018
The upper bolted right up with my lower no problems assembling. Function seems flawless so far. Fit and finish are very good and seems to be a solid piece. I would recommend it to others looking to build a budget weapon.

Good product minus the wait

by Pablo Lozada, Verified Owner from TX, United States Written on September 20, 2018
Assembled 300 blackout upper, sturdy, reliable and very sleek. Just what I needed to complete my AR Pistol. Only setback is the ridiculous wait time. Besides my being inpatient, it seems the product is in high demand and always sold out.

Solid setup

by gijohnny223, Verified Owner from WI, United States Written on April 25, 2018
I purchased this upper for a pistol build and it is 100% No failures shoots consistent groups out to 75 yards. I have no plans on using it for anything further than that. This is with 19.8gr of H110 and a Hornady 110gr V-MAX. I also have the 16" Radical upper in 300BLK ant is consistent out to 100 yards. I used 20gr H110 and Nosler 125gr ballistic tip (green). Price is right and I have no worries of failure from either upper.
Pros:
  • great quality
Cons:
  • Cleaning the oils off when received
Best Used for:
  • hunting or plinking
Would recommend: Yes

worth the wait

by Bart, Verified Owner from FL, United States Written on September 6, 2017
Sure, I had to wait for this product, guess because of demand-but it's worth the wait.

Previously, I bought another SBR from another company but was not the same quality as the Radical Firearms product. This item is much better, you can see the quality and the pride in workmanship.

Functional, performance and priced right.
