Brand new never fielded only had for a few months its upgraded with a maple super leaf 70° bucking and maple leaf hop up tensioner. After I received it I didn't like it as much as I thought so I dont want it. Comes with all original external parts, I will reinstall handguard and heat shield upon purchase. Works perfectly fine all stock except for the parts I just listed. (optic not included) low balls and trade offers will be ignored
