Honestly wanted something that would match the my other stuff I had replaced. Color I ordered was dead match. Found No issues with color distortion, machining, or concerns with threading. Went on like butter and looks great.

We're sorry to hear about your experience, Michael. While our tubes are machined to Mil-Spec standards, Cerakote buildup can occasionally cause tight thread tolerances. We never want a customer throwing away a part, please reach out to our support team so we can issue a full refund or make this right!

Good color, nice weight to it, threads have slightly thicker coating than needed, with the at3 castle nut, it strips off

I ordered the burnt bronze looks high-end but really isn'[link removed] thread tolerances are not that good to fit the receiver that I ordered from you guys

AT3 Tactical · We're sorry for the fitment issues, Tom. The Burnt Bronze Cerakote finish can add enough thickness to make the initial installation feel tight. Applying a little firearms oil or grease to the threads usually helps smooth it out. If it still won't thread on, please contact our support team and we’ll get a replacement sent right away!
