Eddie checks the RA-Tech AAC 300 Lv2 Custom with the WE M4 GBB which is in stock at CRW Airsoft... "Package comes with complete gun & 30-rd GI style mag, 2nd buffer spring, NPAS key. The key is for you to adjust power at anytime (lock back the bolt and tune it from the nozzle hole, no need to take out the bolt).

It sounds very nice when you fire this M4, you can stand on this gun and it won't break due to the high quality forged body. This gun is almost built from all upgrade parts, only little bit of WE original is left.
