Brand: CYMA
Our take: The ultimate in drum mags, this CYMA electronic automatic winding 2500rd drum mag for AK47 AEGs is an absolutely beautiful piece of Airsoft equipment. The drum mag winds without you having to turn a wheel, and is activated with the press of a button. It allows for storage of up to 2500 rounds of BBs and is powered by 3 'AA' batteries (not included). Note that unlike many auto drums, this mag is switch activated and not sound activated, for 100% user control. Note: To fill magazine, remove the black nut on the opposite side of the winding button. Then, remove the entire back plate of the magazine and fill BB's in the sectioned off portion of the magazine. It is compatible with the following models:- ALL JG AK47 Metal Gearbox AEGs (AK47, AK47S, AK47 RIS, AK47 Tactical, etc.)- ALL DBoys RK-series AK74s and AK47s (RK01, RK02, RK03, RK05, RK06, etc.)- CYMA CM028, CM036, CM046, CM048- Cybergun AK47 SpetsnazNOT compatible with:- SRC AK47s- Cybergun AK47 60th Anniversary Edition- G&G RK47sPlease note that all the above compatible models have been tested for fitment. If your AK47 model is not listed, this mag MAY OR MAY NOT fit, so please purchase at your own risk.
