"Not much to say. They’re shims. They’re super cheap, you get a lot of them, and you have more than enough to shim multiple guns. Totally worth it.

"They're little metal discs, can't mess em up.

Only complaint, they come in the same bag so takes a little time to tell the difference between them but overall good product

"They're a pack of shims. They work like they're supposed to and the price is right. This is a must buy for those looking to open up your gearbox and make it run more smoothly.

"These shims are GREAT. I love the .1mm. They are definitely useful when you have just that ('') much extra space to fill in. Also, 40 shims is plenty. I still have about 15-20 left over. Matrix has yet to fail me. Definitely recommend.
