Review: Used for timing - There is a way to tune your barrel for accuracy. My AR is sporting a 3 way prong flash hides so exact placement is a non issue. However I couldnt get my gun to shoot a decent group to save my soul. Used these to play around with muzzle device tuning till my favorite load for another rifle was dialed in. Literally the only thing that has worked. Kindve an old trick but it works! And yes I hand load my own, still couldn't get it to dial in that way.

Works well

### ⭐⭐⭐⭐ They work OK
*by S***J on September 16, 2022*

These work okay, but like someone else mentioned you really need more of a selection to fine-tune it. Also the ID seems too big. I had to hold them all snugly while tightening so that they all stayed aligned with each other.
