Most Helpful Negative Review BAD QUALITY
The quality of the detent pins are very bad. The pins were flat and couldn’t move the safety selector or pull the takedown pins. Save your money and the frustration. Not worth it.

Purchased the Orange and Blue kits

by Todd, Verified Owner from SC, United States Written on July 28, 2026
No issues with this kit, comes with all of the springs and detents, which is always nice. The finish seems durable enough, the blue is bright and solid. Only complaint might be that the bolt catch is just standard black, it would have been nice if it was the same finish.
Would recommend: Yes

Poor quality control

by Chuck, Verified Owner from TN, United States Written on July 24, 2026
The take down detent pins and springs were two different sizes. Bolt catch pin was obviously too big. I tried to use them on a spikes milspec lower and had to modify parts like shorten springs or swap parts with a different lower kit. I tried reaching out to the manufacturer but they seem to be too busy to talk about it. Pitiful fit and finish for aluminium parts. Won't every buy again and will probably replace them with steel parts.
Pros:
  • They are shiny and colored
Cons:
  • Doesn't actually fit
Would recommend: No

overall decent

by murdog311, Verified Owner from NY, United States Written on March 23, 2025
The detent pin for the safety selector was horribly machined , would not allow the safety selector to work whatsoever. Other than that the rest of the kit was okay.

Not as pictured

by Zach, Verified Owner from PA, United States Written on January 9, 2025
I bought this gold plated kit with the understanding all main components were gold. It came and a few were black as pictured but what was not as pictured was the bolt release. It was black instead. OP was great about getting it swapped. Just waiting on the replacement.
