Was not Aluminium, but plastic. Did not fit a M11A1 GBB, only a TM M10. Very flimsy, dissapointing.
[5KU] Steel Hammer Set for Marui HI-CAPA GBB[Type 7]
Great value
Ordered here before with good results. But last order didn’t work out.
As I cancelled it I never received said item, but there was no option to fill out a return form or anything. So i didn’t receive the part nor did I get a compensation/ money back. Maybe my problem of paying with Paypal? I’m not sure. But that leaves a bit to be desired.
So if you want to order here and you know what you need you will get it even if you to wait a bit for it.
But they still need a bit of work regarding returns but we all van learn and make mistakes
