Matrix Ultra Precision Gun Smith Airsoft AEG Gearbox Shim Set (Size: .1mm and .2mm)

"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.

"They're shims, not much to mess up. It is very annoying that they come in the same bag and they're the same color, so you have to sort them manually.

"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.

"pretty good not exactly .2 and .1 at all they all are different sizes still good products and work well just realize that it would be extremely hard to fit that kind of tolerances on something so small and made really fast stamped out of a sheet metal, regardless pretty good for pretty fair price

"Out of 40 shims, (20x 0.1mm , 20x 0.2mm) Only one was un-useable. Not really sure what thickness it is but it's completely worthless.

The shim in question has been stamped so that one side of it is elevated while the reverse side is depressed.

one out of forty isnt a major issue but the rest of them seem to be of favorable quality

"I use these for shimming motors, I would recommend SHS or something else for shimming gears, these also do not come differentiate between the 0.1 and 0.2s so it's difficult to tell. Fine if you just need shims though.

"Great shims, but they all came in the exact same bag. Hard to tell them apart.

"Great cheap shims. Look at the picture though, does it look like 40? mine only came with 20 shims. They also don't label the .02 or .01, so good luck determining that.

"These shims are fine, but they're not worth it. They are all in the same bag. So it is near impossible to tell the sizes apart. Spend a whole 99 cents more and get the G&P shims, which are brass, and they actually have separate bags labeled with shim sizes.

"Would not recommend. Quality wise they are fine, but the 2 size package comes in the same bag. Matrix. W.T.H. If you enjoy sorting tiny pieces of metal in the middle of a project, than go for it. Not happy at all.

"I calipered the shims and the tolerance was all over the place everywhere from .1 to .28 and all.in between and the shims we not seperated by size
