Dboys are known for putting out high performance guns with full metal bodies - all at a competitive price. With the Dboys full metal CASV RAS M4, that has not changed. Sporting a modern configuration for the ever reliable M4 design, this features a lightweight and versatile CASV Rail Accessory System that makes up the hand guard proving rail panels along the entire top length, side, and bottom sections. The top rail is a uninterrupted monolithic rail designed to enhance the stability of the free-floating rail system while allowing users to place accessories at any point on the rail. As with all their guns, the upper and lower receiver is full metal along with the sling plate and buffer tube. The included 300-round hi-cap (high-capacity) magazine is metal as well. The only plastic parts found on the gun would be the pistol grip, butt stock, PEQ style battery box, and vertical grip just as found on the real steel firearms this airsoft gun replicates. Internally built with a full metal 7mm gearbox that outputs a 420 FPS muzzle velocity.

Please note this gun does not come with a battery and charger, however investing in a stronger 8.4V or 9.6V battery and a smart charger is always a recommendation - oppose to using lesser batteries and chargers that other airsoft guns often come with. This gun was designed for the player who wants to take a serious step into airsoft without the unnecessary high cost of admission.

  • Dboys CASV M4 Airsoft Gun
  • 300-Round Hi-Cap Magazine
  • PEQ Style Battery Box
  • Vertical Foregrip
  • 420 FPS

great gun January 29, 2012
Reviewer: Alex koval from Reisterstown, MD United States  
At first i had a couple of issues with it but thats most likely because i am new to airsoft but i understand the gun now, but its a great gun to play with and after u get comfortable with it, it will be like your best friend on the field. It is kind of hefty to carry around and the battery placement is kind of annoying to me but besides that its worth the price :DDDDDDD!!!!!!!!!!
