"I bought these for my JG SG550 gearbox (yes it is the original gear box). They fit perfectly. I applied a little silicone grease and the popped right in. Worked fine with the stock gears also. These are for my DMR setup and I would recommend these.

"After purchasing my AUG, it arrived with stock nylon bushings. These were fine stock, but I wanted to up the power and speed of the gearbox. Therefore, I needed metal bushings. I incorrectly ordered 6mm bushings without hesitation as I had never heard of 7mm nylons before. After attempting to install them, I found that they were the wrong size. However, Evike's amazing customer service responded by exchanging the bushings for 7mm and paying the return shipping. I had some difficulty installing them due to a tight-fitting gearbox. I had to hit them with a hammer for them to seat properly. However, the bushings did not deform at all. For $12, these are amazing and durable.
