Good quality easy to use very durable fit perfect so great functionality and a great value for the money made of durable metal

### ⭐⭐⭐⭐ Nice to have for tuning headspace!
*by A***M on May 23, 2025*

I have a benchrest 457 that I've been slowly improving over the last few years. The Lilja barrel I bought for it came with it's own headspace adjustment shims, so I didn't need these for mine. I did, however, purchase a smaller Scout model for my children to learn on, and I wanted to accurize it a little bit. I was able to get it shooting a bit more accurately with the bulk SK I bought for practice, but I really wish they would have included .001" shims to really dial it in better. The smallest size here is .002" Nice little kit to keep on the work bench!
