Two multi-magazine units (for electric handgun G18C) with other extras *Please read description

This is a set of 2 multi-shot magazines (for electric Glock 18C). Various extras are included as a bonus.

Breakdown:
Multi-shot magazines x 2
Normal magazines x 2
Nickel hydrogen battery
Nickel hydrogen battery charger
LiPo battery adapter
Part of shims removed from gearbox (2 pieces)
Long inner barrel
Normal inner barrel
Silencer (for long inner barrel only)

Main unit (with defects*)
No returns or exchanges, please.
*Currently, it does not fire BBs. We have a general idea of the cause. However, since we know we won't have an opportunity to use this gun even if it's fixed, we are listing it as is with defects (effectively junk).
There is a laser-etched marking on the slide.
Please consider it as a bonus for parts harvesting.
Replaced parts are as follows:
- LayLax Hard Tapet Plate
- Unbranded New Motor (6 months ago)
- Metal Gearbox with Bearings
Sometimes, when in single-shot mode, 2-3 BBs are fired in burst.
The screw holding the slide rail is stripped.
There is also one stripped screw in the gearbox, but that screw can still be fixed and removed.
(Addendum)
Currently, when the battery is inserted and the trigger is pulled, the motor spins freely. This is likely because the shims in the gearbox gears were removed during the last disassembly and maintenance. We are including the shims that were removed along with the gearbox screws, so if you are able to disassemble it, we would appreciate it if you could try this.
