Mostly Tokyo Marui mp5 A5 Parts that are marui: upper body, complete gearbox, handguard, outer barrel, stock. Everything else came from my box of marui spec mp5 parts. Is r-hopped and functions perfectly. The gearbox has never been tampered with and it has it’s original marui eg700 motor. The fps is somewhere between 280 and 300. NO TRADES, BUYER PAYS SHIPPING.
