Opknapper: Colt M4A1 CQB cybergun AEG

I am selling my Colt M4A1 (Cybergun) due to a clearance.

This M4A1 is full metal and has always run on 9.6V 1600mAh Mini Tamayas.
There is room for a nunchuck battery in the stock.
Comes with original metal high-cap magazine and the box (slightly damaged).
Front Grip is NOT included. (I do still need it 😉)

The replica has 2 internal defects. Since I am not yet technically proficient enough regarding airsoft replicas, I would like to offer it to a handyman who would like to build a project or restore it.

The 2 defects:
- No more BBs are coming out, perhaps a hop-up problem? (BBs fall out when I remove the magazine)
- Magazine doesn't stay in properly anymore, falls out.

I think these are both easy fixes, I don't know. Given the condition of the replica, I obviously don't expect a high price for it. I look forward to your bids.

Regards, Rens
