Empty Chamber Indicator / Safety Flag for MP5 platform. Designed so you can close the bolt on the flag and the receiver will not cut the flag's arm off. Hole included for attaching a lanyard, elastic, or keychain. REMOVE BEFORE PEW PEW!

PETG at 100% infill

Fusion360 file included if you want to remix, or add a void for a magnet. I couldn't get mine to stay affixed to plate after adding magnet - would be a great addition if you can get it to work.

Fits my 9mm AP5-P and Ivan's KF5/SF5, will likely fit any other clone or variant. Chamber peg is 8mm diameter, body is 14mm diameter, so should fit 10mm chamber as well.
