I really dont care on what gun its based off of. I just dont want an M4, m16, g36, or ak47 platform. Other then that im open to anything. If i have to i can take one of the earlier mentioned that i dont want but i just dont want to have to unless its my last resort. It just needs to cost under 200$ for the gun itself. Other then that i just want something that will look unique but also is going to be easy to upgrade. I really dont have a preference on what version of a gearbox i need or anything. It also does not need to have a fire selector switch on both sides. And RPM doesnt matter as the field i play at only allows semi auto indoors due to insurance restrictions.
