Solid choice upper with heavy barrel with A2 flash hider and M-Lok handguard by Stevey GB, Gear Expert, June 12, 2023
Rugged-looking upper in 5.56 with heavy nitride barrel, A2 flash hider, M-Lok handguard, and basic BCG and charging handle. Runs like a champ. Gun keeps zero better than thin barrels when hot. Love that it eats all .223 and 5.56 loads. Handguard look...

Helpful Positive Review Better than many others... by S. Templar, D.D., Verified Owner, May 22, 2024
This upper is of very good quality. It isn’t a Premium Grade upper, but it is higher quality than many of the entry-level options that are out there. I have three Trybe uppers, and they are all about equal quality. I would put Trybe uppers on par...
