Prometheus Gearbox Shim Set for Airsoft AEGs

"I was told to be careful buying shims because many are bad quality but these were very nice. It came in a small plastic bag and there is no way to differentiate them other than by feeling them but they worked great when shimming 3 different guns. Would buy again.

"nice shims, more than enough to shim multiple guns

"easy to identify what's what.
good, will buy again

"Best shims I’ve tried, super precise, and most of them were within .02 mm of their desired widths. I’ve bought a pack of shims from an inexpensive airsoft manufacturer and I’ve had to take a pair of calipers to them every time because they are inconsistent. With these Prometheus shims, I don’t have to do that. Quality over quantity.

"i love these. comes in all the sizes you would need to achieve the perfect shim job. its nice they have a diagram on the back to tell you which ones which. highly recommend!

"I've bought LITERALLY every shim from every maker on this website and these are BY FAR the smoothest and most precise shims out there. 10/10
All other shims didn't measure as great as these sis on my calipers.
HIGHLY RECOMMENDED!!!
