Most Helpful Positive Review Patience is a virtue
This is the best upper I own to date however acquiring it requires patience. When I was looking to buy a top of the line upper I was contemplating between DD, Geissele, BCM and Sons of liberty gun works. after eyeing the markets and noting nothing has been in stock for months besides DD, Geissele an...

Most Helpful Negative Review Great upper, sub-par build quality
The 14.5 upper has a pin/weld muzzle device. Radian DOES NOT take the time to properly time the muzzle device. This results in your pin/weld location in random visible areas which makes attaching a suppressor a guessing game. It also results in the pin/weld mark in visible areas instead of the 6'Ocl...

My favorite Upper

by Oscar, Verified Owner from FL, United States Written on April 2, 2025
I swapped out my DDM4V7 upper with this 10.5 Radian. I'm impressed. Fits perfectly. I've put a few hundred rounds thru it and have really enjoy'd it. Honestly, I get more fun out of this setup than i do with my 16in DD upper.

This will not work with my DD AMBI Lower

by Deuce, Verified Owner from NV, United States Written on June 17, 2023
On my DD ambi lower, this upper will not fit. The forward assist hits the right side bolt catch. So I can’t even line up the takedown pin. If you look at the Radian ADAC-15 lower, the bolt catch on the right side does not sit up like a typical one. So it won’t even mount to my lower.

Now I’ll have to buy the ADAC-15 lower and build it. Not the end of the world, it will get done. But had I known before, I would have sought out the Model 1 complete rifle instead.
Pros:
  • Build quality
Cons:
  • Will not match up to every AMBI lower
Would recommend: Yes

best upper ever

by Juan Marmolejo, Verified Owner from GA, United States Written on October 18, 2021
As a former W1 SOC medic I thought benchmark upper was the MK18. This blew my mind. It just feels special in your hands . Hands down beats any high end rifle on the market. I will definitely come back and buy more stuff from radian

perfect upper

by Mike, Verified Owner from NJ, United States Written on June 1, 2021
The radian upper is as good as it gets. Optics planet is as well. The 14.5” is the sweet spot and the attention to detail is second to none. Buy with confidence. The fit and finish are top tier. The performance is elite.

Worth Every Penny.

by Samantha Macarages, Verified Owner from NC, United States Written on March 15, 2021
I decided that I wanted 1 solid AR15 at least in the 16" configuration. Rather than buying multiple ARs I decided to spend the money on a top tier rifle. I bought Radian's ADAC lower a while back doe thr ambidextrous controls. There is no play with the upper and lower. It is super tight. The grey finish looks super clean too. I knew I'd have to wait a while to receive it, but it was actually cheaper to order through Optics Planet than it was Radian. I highly recommend this upper!!
Pros:
  • Quality, Performance
Cons:
  • None
Best Used for:
  • Fun at the range, home protection
