Always wondered what other sites stipulate. With the Titan MOSFET you can electrically change the fire selector, Safe-Semi-Semi.
However havent been to a site that has vocally allowed this yet.
The DMR I had was a purpose built lower receiver so it didn’t have Full auto capability.
You can set a normal AEG to semi only in multiple ways, some a bit Heath Robinson, some quite smart. Have a google and search the forum.
