mG36 has broken gears and piston

My mG36 that I broke on Hurtgen reenactment game and left for repairs couple of days ago was diagnosed today by a friend of mine. He said that all the gears in the mechbox and the piston are broken (literally into pieces). He also said that it was because the spring was too weak for the battery voltage I used (9.6 V 4,000 mAh capacity NiMH battery). The rate of fire was so high that the mechbox malfunctioned and it caused all the damage.

The spring will be replaced with a more powerful one.

I wonder how much will I pay for the repairs and for the replaced parts...

mG36 and M24 dropped for repairs

Being today in Warsaw, I had a chance to meet with one of my teammates who recently started working in one of local airsoft shops. I wanted to meet him, because in his work he repairs airsoft replicas, and I wanted to leave him my broken mG36 and M24.
