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.

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.

ok if u want color with some issues.

by N8, Verified Owner from WI, United States Written on March 2, 2024
I bought 2 of these. One purple and one blue. His and her builds. So far, i have used the purple one. And right from the get-go, i had issues. The first issue i had was that the magazine button had the wrong threads in it. The mag catch would just slide right through it. The second issue i had was the safety switch detent. Just from the weight of the detent itself. The safety switch would not rotate. The tips on the detents suck. As soon as i put one i had from aero precision. The safety switch worked fine even under spring tension.
The coloring seems to come off easy.
These are ok if you want some color, but ultimately they are NOT worth 3 times the cost of a standard lower parts kit.
I have contacted guntec to see if they will send me a new purple button.

Springs and Detents are Trash!

by Josh R., Verified Owner from NC, United States Written on February 28, 2024
I should have read the reviews before I bought it. I had to throw away all the springs and detents because they were horrible. Safety would not rotate with the provided detent as the end was too flat, once I replaced it with a spare, I had from Aero it worked. Same with the detent and springs for the takedown pins. I also had to take a part both sides of the safety because they were installed backwards. If you buy this because you really want the different color parts, beware that you will need to replace all the springs and detents as they are defective.

Looks good but parts not milled correctly

by Bob112233, Verified Owner from IL, United States Written on December 5, 2023
The colors look good but after fighting the install for longer than I should have I ended up replacing the detents for the pivot pins and safety. Luckily I had a spare lower parts kit and could take from it. The detents were not made correctly. The colors did look nice and as expected.
Pros:
  • Colors look good
Cons:
  • Parts don't fit
Would recommend: No
