I'm thinking of putting together a nice cqb gun. I already have a JG for field so I don't really need another. I'm thinking of a combat machine. My budget is no more than $250 and I want an m4. I figure I will just use my woodland loadout, and mag midcaps that I already have so I don't have to buy anything else. Heres what I was putting together: http://www.airsoftatlanta.com/G_G_Combat_Machine_M4_CM16_Airsoft_Gun_Black_p/35014.htm?CartID=1 http://www.airsoftatlanta.com/SHS_High_Speed_Motor_Long_p/32726.htm?CartID=2 http://www.airsoftatlanta.com/PDI_100_AEG_Spring_p/65359.htm?CartID=3 http://www.evike.com/product_info.php?products_id=38524 I already have some 9.6v 1600mah minis. Will those fit in the handguard that I just listed? Also what fps and Rof would I be expecting with them? Oh and I already have a madbull blue bucking.
