Pay attention to your threads - Guntec USA AR 9mm Mini Slip Over Barrel Shroud w/Multi Port Muzzle Brake

Can't blame anyone but myself for the error but I got the wrong thread size. It was buried in the description and I just assumed I had ordered the 1/2x28 that I needed but really ordered the 1/2x36. So, not realizing I had the wrong size, I proceeded to screw the shroud onto the barrel by hand without any noticeable resistance to the threads being incorrect.

When I thought that the shroud was getting tight by hand, I used a strap wrench to get it tightened down even more. After cycling the rifle a few times, I could feel the shroud was coming loose. I realized that it was coming loose due to the threads being wrong. Since I tightened the shroud with a strap wrench, I knew that it was coming loose because the threads were stripped out.

My only complaint is I wish that I would not have been able to thread the device onto the barrel due to the thread difference and I almost feel like the threads are just very thin which allowed the device to thread with little resistance.Fast forward a bit...

So while Optics Planet did nothing wrong and I did not try to return the shroud, and the part was in perfect condition, I did reach out to GunTec just to let them know what my concerns were regarding being able to thread it on even though it was a different pitch. They did not even have to respond to me. Not only did they respond, but they offered to exchange the part I mistakenly ordered (and subsequently ruined) without batting an eye. What amazing customer service. Thanks Optics Planet for doing business with GunTec and carrying their parts and Thanks GunTec for great customer service above and beyond what is necessary!

Highly recommend the part, Optics Planet, and GunTec!!
