Now available at Airsoft Unlimited... "Well... it's an Echo 1 M8A3 with STAG trademarks. So what makes it different from a standard M4? This gun uses an M4 type lower receiver and accepts M4 magazines... however it features a long barrel with a quad rail system. It h­as flip up style, adjustable sights, and a collapsible stock. There's also a top rail across the upper receiver with no carrying handle.

This baby comes with a battery inside of a PEQ box. So while it is an M4 / M16 variant, it comes with a lot of options not usually found on a bone bare stock gun."
