"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.

"Best AEG Shims I have ever used. It has the most useful 0.1mm that are hard to find in Systema and ICS shims. Then some 0.2mm when you need thickness.

For serious gearbox shimmers that wants smooth rate of fire, these won't disappoint you.

"Outstanding shims. Got my new gears sounding nice and quiet. Will buy more of these when I run out. Only issue I got with them is the bag kinda sucks and doesn't separate the 0.1 and 0.2 mm shims. So I had no idea what size shims I was putting on my gears. Sometimes I could use different shims and it would loosen the gear enough so there was no axial movement. Just get the package for 0.1 mm shims and use 2 shims for 0.2 mm. Other than that gripe, they're quality shims that you can rely on.

"They're decent shims, but it would be nice if I could tell which ones were which. They get the job done, though.
