that is the sort of thing you need, but be aware it might need alot of fitting.. i'll see if i have a spare one back in england when i'm next ofer there.
this has happened when i attached a slightly-too-heavy silencer to my WA it's a known point of failiure
by any chance does anyone have a metal (or plastic) 3.9 inch slide for the old R system.
http://www.prog4.com/db/product-show.asp?refno=AR1626 is an example
desperate to know of anywhere that has them (pro4 is sold out and elite airsoft in the UK advertises them but sends 4.3 slides and bitches at anyone who doubts them)
sorry for the thread hijack
