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

"Good shims, you get more for cheaper than other sets.

"Fits nicely on my gears and my gearbox is running much more smoothly than when I got it. Thank you!

"Good quality shims, Consistent size when verified with my digital caliper.

"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.

"very precise shims. works good in my v2 gearbox high speed build

"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

"Everyone that opens a mech box should have these.

Pros:
Good price
Bag is resealable (kinda)

Cons:
Doesn't come with .15mm

"Great shim, precise, cheap, and well made. Highly recommended for everyone!

"Works like a charm. Nothing really to say but they work.

"high quality, worked great. would buy again

"Great shims, Just used them to re-shim my ics cxp15, great price! A must if you haven't re-shimmed your AEG since you bought it.

"Great shims. gets the job done and is made well.

"Great shims.

was enough to reshim 5 of my gearboxes.

"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.
