Ratings & Reviews
No malfunctions. Great fit and finish. Unbelievable value.
Very surprised by the quality of this build. This is a great deal. Fit and finish are perfect. It fits perfectly with every lower I own: Spike’s, Aero Precision, Anderson, PSA, S&W M&P. No wobble but not overly tight. Makes me question why I have spent $1,000 plus on “Gucci” uppers.
Great upper. No malfunctions.
300 rounds, no malfunctions. Theres a couple things that stick out of this upper One being the barrel. I'm not sure who the manufacturer is but it is very nice and has a great looking nitride finish. It appears to be of higher quality than PSA and other brands at this price point. Great fit and finish. Lastly, the M-LOK rail is practically designed for a Magpul AFG Angled Foregrip. It fits like a glove and looks amazing.
