Tokyo Marui M4 CQB-R Recoil AEG (Dark Earth) The Tokyo Marui M4 CQB-R, represents TM's new venture into recoil AEGs. Representing the forefront of TM's production line, the SOPMOD series AEGs have an internal blowback mechanism to replicate the recoil felt with a real firearm. Extremely rare and hard to find, the M4 CQB-R is an awesome AEG and is the favorite of Airsoft Atlanta Staff and players. This new model features a full metal body and RIS that is a 1:1 replica of the real deal. The barrel has been shortened to make it more ideal for close quarters batter, but useful in medium range engagement as well. It has a functional dustcover, bolt catch (it's an automatic cut-off), short foregrip, and "Real Cap" style magazines. The included 82 round low capacity magazine has a flip switch that allows the mag to function similar to a 30 round lowcap. Simply remove the outer magazine casing and flip the switch on the side of the plastic to enable. The high capacity replacements hold 430 rounds. The battery compartment is located inside the crane stock and uses a proprietary battery developed exclusively for Tokyo Marui's use on the SOPMOD. Remove the butt plate and the cap and the battery slides in and connects easy as pie. The rifle is able to use regular Marui M16 mags if a special feed adapter is added to the top of the magazine. Airsoft players absolutely love the M4 CQB-R for it's beautiful detailing, realistic operation, and the number of accessories available for easy addition. *Note: The TM SOPMOD M4 can only use the TM SOPMOD batteries and magazines. Modification to the rifle is not advised and can cause irreversible damage.
