The silenced AUG...

I just got back from Majki's home. I went to see him to install the tuning parts I ordered for my Steyr AUG Classic Army replica.

We installed the bore-up set and the spring guide with no trouble at all. It's easy so we didn't expect any difficulties, we only thought that positioning the gears with shims will take the most time. And we were right.

I wanted to put the ball bearings inside the holes in gearbox only to find out that I ordered 6 mm bearings while I should buy 7 mm set. So the ball bearings went back to the box and the original bushings were left intact.

Majki put the helical gears inside the gearbox. He closed it, attached the motor, and tried to fire the gearbox. The motor mover the gears a bit and stopped. We thought that the battery was not charged enough (what's odd -- it fired the replica in its original state) and attached second battery, with no effect.

It took us some time to find out that one of the teeth on the spur gear was broken and we had to use the file. After that and putting all the shims we thought we need we closed the mechbox. Nevertheless the battery was not able to move the piston so we put together the replica and I went home.

At home I plugged a fresh 1,200 mAh battery to the replica and it fired easily.

I thought that the Steyr AUG after these alterations will be silent. I was wrong. It's much louder than originally. It sounds like a drill. Since you have your ear next to the gearbox it is not pleasant to fire the replica. :(

So it seems I threw $200 down the silent toilet. :(
