Modify Metal Precision Complete Airsoft AEG Gearbox Shim Set

"These shims are great, I bought some to shim my M4 and ARP9 and these shims work really well. The different sizes make it easy to tell what shims are what thickness and it makes it so that it doesn't matter if I get them mixed up. They are pretty strong and durable too. I really like that they have a .15mm shim as it can help make your shimming more precise. Overall I would recommend these shims to anyone who is shimming.

"Best shims. I use these in all of my builds now. I especially love the .15mm shim to fill in those spaces just right. Most others brands don't have that "in between" size like that. They are also strong unlike the crummy copper shims.

"Very solid shims, I use these in every build I do. Some different brand shims tend to bend from time to time causing some potential issues, I have yet for one of these shims to bend. The pack comes with a variety of different sizes also, making fine tuning simplistic.
