[Solved] Marushin M1 Carbine NBB
Before Marushin made the more common GBB M1 carbine (still hard to find nowadays) they originally made some NBB variants such as this one. This is a Marushin M1 carbine 8mm NBB, in great condition with 1 leak free mag and comes with the small bolt attachment if you want to increase the reload speed, but I preferred the look with it off so didn't use it.
The NBB model is more accurate, more gas efficient and has a higher fps too compared to the GBB model. I'm only selling this to fund my SVT 40 project, normally I'd be keeping it.
