Most Helpful Positive Review Fantastic upper but wrong item to what’s advertised.
Amazing upper, smooth as silk once the gas block was adjusted. Fit right on an m4e1 lower with 0 problems. Wish it came with the Q BCG and it showed up with the Clear ano hand guard as opposed to the cerakote.
Most Helpful Negative Review Wrong BCG and color
This listing for the 13” 5.56 Q upper shows the handguard as black handguard and tan upper a quick Internet search of the part number 850035705087 backs that up. Also this did not come with Qs 2 piece BCG , it came with a black non branded BCG, it did include the radian charging handle that you woul...

Q... Quality without Question

by S. Templar, D.D., Verified Owner from WV, United States Written on December 31, 2025
I have extensive experience with the AR platform. From top to bottom tiers, from old rattlers to ultra-tight comp weapons. This is my first entry-level Q upper.

Overall, I don't see how anyone could complain one iota about the quality of this upper. Everything is well executed and tight. The heavy barrel is top-shelf stuff.

I did replace the generic afterthought BCG it came with. I installed an Angstadt carrier with a Sharps DLC Reliabolt. Since they don't, or didn't, normally include a BCG with this upper, I expected to provide one.

Excellent build. Fantastic execution. Easy to adjust gas block, even in 5.56.

This good doctor's opinion is that this is a great choice for anyone looking for a high quality upper for their next build. She's attractive, reliable, and strong.

Highly recommended!

Buy for Q not any other reason.

by Allen Williams, Verified Owner from GA, United States Written on August 30, 2025
Anytime a Q product is purchased it’s 100% worth it. Mine sowed up with the 2 piece bolt and honey badger radian. It was missing the gas block and the situation could be handled better. All in all the quality of Q and Q customer service is unmatched.
Pros:
  • 2 piece bolt HB radian
Cons:
  • No gas block on a complete upper
Would recommend: Yes

ABSOLUTE STEAL

by Baked.Baker, Verified Owner from FL, United States Written on May 27, 2025
This upper (13in 300blk) retails for $1250. I paid $830 shipped (on sale & used a 12% code).
If you're looking at this upper id, recommend possibly holding off to see if you can catch it on sale. Came with Q's 2 piece BCG, Radian charging handle, Q cherry bomb, adjustable gas block. For $830, absolute steal.

As of writing this review its back on sale for $889.99
Pros:
  • Came with Q's 2 piece BCG
  • Radian charging handle
  • Q's adjustable gas block
Cons:
  • None
Would recommend: Yes

Q Sugar Weasel 13” Upper

by Eric, Verified Owner from AZ, United States Written on May 13, 2025
Fantastic upper. I really like how easy it is to access (right side of handguard) and adjust the gas block to fine tune for your specific ammo. I’m getting good accuracy with all ammo grains I’ve tested— 55gr/69gr/77gr. I’d absolutely recommend this upper.

Q Sugar Weasel Upper (.300 BLK)

by Q LVR, Verified Owner from GA, United States Written on April 18, 2025
Shipped to me insanely fast (3 days). Fitment on my M4A1 lower is perfect with no movement or rattle. Came with a Q BCG and Radian Raptor charge handle which was amazing. Shoots perfect. Couldn’t be happier with this purchase.

Great buy overall

by MOB, Verified Owner from NJ, United States Written on November 23, 2024
Happy with the purchase, just wish the description was lacking when it came to the details. For example, buying a Q product you'd expect there to be a Q BCG included.
Would recommend: Yes
