hay I have a UKARMS zm51 that I would like to trade or sell. It is in extremely good condition, it has not scratches or marks. It is brand new, just got it two days ago. Shoots well and it strong. it is made out of plastic and it semi light. It comes with a scope, but it an a cog that looks real. It also comes with a bipod and it is also plastic. Comes with a speed loader and tool to put together gun. It also includes a strap, BUT it was broken when I received it. Other then that it is a really good gun.
