Small update..

I took apart the gun again to fix the wobble on the grip and trigger assembly which wobbles back and forth independant of the receiver. The issue seems to be with the front of the trigger assembly caused by slack between the mounting point and assembly housing. I filled the gap with JB Weld since this point has no reason to pivot around the front pin. Further to that it physically cannot pivot more than about 3 degrees unless you remove the front bracket anyway.

I had to remove my gearbox in order to access the screw to drop the front bracket on the trigger assembly. As I removed my gearbox I noticed a small ball bearing drop out. Turns out the exact same bearing that blew on my M60 blew on my MK46. My assumption is that this is a high stress point for the gears, see this post for the M60 issue: Airsoft Canada - View Single Post - A&K MK43 Mod 0 - Initial Impressions and Upgrade Thread

Now this is both surprising and fortunate. I have only about 1500 rounds through the gun, all from FPS and ROF testing (and because it's fun to shoot... I sometimes need to really make sure that my ROF is accurate, and 400 rounds later...) So anyway 1500 rounds through, hence surprising, and fortunate because I discovered this now and not 10,000 rounds later at the end of a game as my gearbox locks up.

I had done some research and it looks like the CA gearboxes, and I assume A&K 249 as well, use 8mm bushings. Our team took advantage of the boxing week sales @ Airsoft Store Canada so I picked up some Lonex 8mm Bushings with the intent of swapping these into my gearbox. A Little shocking though @ 1500 rounds...
