Gen4 Micro for grabs $250
Gen6 (mm2k9) Micro for grabs $600.
Firm on prices for both.
Gen6 comes with a rare WWA shortly barrel, Xvalve-L10.
Gen4 is bone stock with an Automag valve / ANS back, L7 (I think short nosed one)
Before anyone asks, the Gen6 has the body steel ring / insert, no velocity issues.
