I purchased the 8 inch 300blk upper and probably have 500 rds through it currently.

well made over all

by Nadeem, Verified Owner from VT, United States Written on February 5, 2025
The upper was leightweight, well built, charging handle was nice and muzzle flash. Polymer upper. Only draw back was front take down pin hole was very tight. Had to file down a bit. Other than that, very good and smooth.

blown away

by MuGGzy, Verified Owner from OR, United States Written on November 26, 2024
Never heard of the brand but this upper was less than half what others i was looking at were. Pre matched parts make it pre tuned basically.
It also has some sweet weight reducing milling. So far it cycles 300 supers right out of the box on the lower from another gun running a carbine buffer.

Exudes quality

by Nick, member from Fl, Verified Owner from FL, United States Written on June 23, 2024
The fit and finish of this upper assembly exudes quality from end to end. Have no lower to put it on yet but I have no doubt it’ll perform very well once it’s completed. The quality for the price I paid is well worth it!
