"Very solid shims, I use these in every build I do. Some different brand shims tend to bend from time to time causing some potential issues, I have yet for one of these shims to bend. The pack comes with a variety of different sizes also, making fine tuning simplistic.

"These are the only shims I use on my guns. There may not be alot in the package but the diameter-thickness construction makes shimming a gearbox so much simpler and takes the guesswork out of the process. I absolutely recommend these shims over any other type/brand.

"Surprised there are no reviews on this, they are great!

They come in different diameters, the different diameters correspond to their height making shimming a breeze.

Get these over any other brand. No need to guess how thick they are, packaging has a table with thickness of shims.

5/5 Will buy again
