## Customer Reviews

### ⭐⭐⭐⭐⭐ Most non-AR rifles.
*by K***Y on April 7, 2023*

Works great for most rifles. Needs an adapter for AR styles, not sure if I can buy or have to create.

### ⭐⭐⭐⭐ no operators manual
*by R***Y on April 8, 2023*

i woukd prefer a manual that tells what calibers are in the area of the arbors, i have a 308/7.63 i had to play with the arbors to find out which one to use. same thing with a 5.56, haven't got to the 270 yet. when i found the correct arbor i marked it with tape for future use for my sons.

### ⭐⭐⭐⭐⭐ Great tool.
*by D***H on November 7, 2022*
