The bearings are only for getting that nice smooth clicking sound when your bolt locks and unlocks, remove the springs if youve lost the bearings, as they will only damage further. Use threadlock, the blue stuff on the bolt lever screw, once youve found a replacement for the springs/ball bearings then remove the bolt lever, replace and threadlock again.

Your magazine will not go into the gun if
1) Its loaded FULLY to 25 rounds. You can only have 24, and +1 in the chamber, otherwise there is no space for the nozzle.
2) If your hop up chamber is slightly twisted, it will chop the feed lips of your mag a bit on the sides, preventing it from sliding in.

I also recommend using a very light silicone grease on the cylinder itself. The lubrication it comes with out of the factory sucks, and you'll end up scratching up your nice chrome cylinder (assuming you have a V3) and the cocking is much chunkier. A VERY LIGHT coating of silicone grease will smoothen it up significantly and reduce the friction noise of cocking.
