Most Helpful Positive Review Good for Retro style build
Luth has upped their manufacturing, this newer model has the m4 feed ramps and is milled to spec, the barrel nut lines up perfect to the bolt (they had issues in the past) and all parts fit as expected. I personally prefer the A1 vs A2 carry sights and used this for an CAR15 clone build, turned out ...

Most Helpful Negative Review Poor machining
After a 2 week wait in shipping from Optics Planet I received my much awaited C7 style upper for an Operation Gothic Serpent build I was doing. Opened up the box and pulled out the upper from Luth-AR and sheer disappointment set in. One side of the sight rail measures .060” and the other measures ar...

Seems fine

by Matt B, from CA, United States Written on September 22, 2021
Seems fine but have not yet finished assembling the upper. Finish is acceptable. Note that the Luth ar a1 sight does not install well in this upper due to the out of spec leaf spring. You would think there wouldn't be a compatibility issue when using the same brand of parts.

C7 clone build

by Ivan, from TX, United States Written on September 4, 2021
Wanted to build a clone of a colt 733. This was the exact upper I need to complete. The fit and finish was good. I can’t wait to complete the upper. These uppers are hard to find get them while you can.

poor quality

by Huckleberry, Verified Owner from AZ, United States Written on June 1, 2021
I ordered the Luth-Ar A1 style stripped upper for a retro build and wow, is there any quality control? The carry handle dimmensions look way off when looking down the rear sight because one side is super thin and the other side looks fine. Im no A1 style expert but im pretty sure they botched the carry handle. My othe problem is the rattle and gap between the upper and any lower you put it on (I tried 3 different ones). And lastly, the finish is not retro grey but something else that feels like medium grit sandpaper.
Would recommend: No
