Hello shooters,

during cleaning my MR223 i found this broken part, but i do not know where it comes from? On explode view isn´t this part. Maybe is part of any bigger assembly?

Thank you for help, Hawk

Itˋs a small spring located on the rear pin hole in the upper receiver. Not really necessary, just for reducing the wobble.
