## Customer Reviews

### ⭐⭐⭐⭐⭐ Glossy finish, not flat as advertised
*by D***. on November 24, 2023*

Shipped pretty quick. Good fit and finish. The finish is shiny which looks a little ..special... on a flat black nitride barrel. Used a rubber strap wrench to torque, which prevented scratching while assuring it will not come loose during use. Great seller!

### ⭐⭐⭐⭐⭐ Fits just right
*by A***O on September 4, 2022*

Used this on a Brownells Retro AR upper fits flush with the barrel fine.

### ⭐⭐ Well made but they don't work for what people are buying them for
*by S***L on January 3, 2025*

Folks online are getting these to smooth out some poor fitting suppressor sleeves or at least even them out. Though these are very well made they are machined too large to fit and the suppressor simply won't go on defeating the reason for buying these. For decorative use only they are fine but sadly were so close. Super dissapointed.
