yeah, it shoud fit, you will have to drill the stricker for the F1 out, and use a Raptor conecting pin. I would get a whole gun from ebay, or here, I found you one;
just use all the guts from it.
or.... you could ask Dadyo what color he wants his "New F1" to be.......and find a corresponding Raptor to trade him, and if it is any good, sell me the connecting pin from the broken gun. lol then we are all happy, good luck
