WKOOA 1/2x28 Barrel Shim Kit 5.56 223 Muzzle Brake Alignment Pack of 12

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

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.

Wish they were slightly undersized, but they do the job. As described. Edit: Update, well my buddy got a use out of the larger shims so that's good. Giving extra star for my buddy being able to utilize what I didn't need.

Recommended per their listing.

got a couple packs not knowing how the setting of timing on new compensators would go. It was trial and error and more error until aaaah just right. two firearms were addressed and eventually both got the right combo of washers added to make a perfect fit which is returned to after cleaning without flaw

Was exactly what I needed, and worked as intended.

Great item does what is supposed to
