Most Helpful Positive Review If you ever remove AR Barrels!
If you pull apart your .308 up to removing barrels or plan to. You should keep a set or 2 of these on hand. Some barrels need them some do not. If your barrel is shimed removal can mess thin shims up. Having all this kind of little stuff on hand has simply made messing around with configurations way more possible. Sucks when you just about have your new build or replacement complete just to find you have to order parts.

Great Item

by Chris, Verified Owner from NY, United States Written on October 27, 2024
Good quality, I recommend getting 2 though...the barrel nut was so in between mounting holes that I actually needed a few more...I made it
work just by tightening and retightening multiple times. After the next to last seating, I checked on the shims just to make sure they were good for a final clamp down (sometimes the paper-thin ones can get damaged) and they looked excellent...don't hesitate to buy just make sure you get enough.
Pros:
  • Perfect Fit
  • packaged well
  • Good Quailty
Cons:
  • None
Best Used for:
  • ar - 10
Would recommend: Yes

These shims are the way to go

by George Williamson, Verified Owner from NJ, United States Written on May 15, 2024
These shims come in a pack. Are stainless steel and there are multiple different sizes from .002" to .010" with 2 of each of the thinnest ones. I have used these for multiple builds. And I highly recommend them.

These shims work great

by George Williamson, Verified Owner from NJ, United States Written on May 8, 2024
There are enough shims in this pack of different thicknesses to shim any AR10 platform barrel. And they are stainless steel.

This shim pack is perfect

by George Williamson, Verified Owner from NJ, United States Written on April 27, 2024
This shim pack has enough shims to adjust any barrel nut on an Ar10. So far, I've used them on 5 builds. They work perfectly.

Necessary part

by Weebs, Verified Owner from MO, United States Written on January 27, 2024
Did what I needed it to do. Shimmed the barrel nut out enough that I could get it aligned within the specified torque range
