MAS Magic Pin
*Currently in production - ETA May 2023*
The MAS Magic Pin is a 3 piece screw in body pin for M4 AEG. As the screw is tightened the middle of the pin expands to provide full lockup against both receivers.
It's also useful for AEGs with a worn down pin hole or upper receiver wobble.
We are working to implement the Magic Pin on the upcoming Marauder, Blackout, and Vanguard series AEGs.
