G28 help

[terrier]

Hi need some help managed to bag a unicorn vfc g28 however it's shooting full auto when you full rotate the selector switch when it should still be single shot. Anyone got any ideas never teched on a gbbr so want to pick some brains before working on this beast. 

 

Cheers

Good find

Though I’ve never seen one in the flesh can I have a stab at it?

 

I know some gbbr’s are sensitive to over lubing, check the sears and trigger group in the lower receiver, if it’s got loads of grease in it, I’d clean it out and try it almost dry.

Then re lube with a gun oil and see how it fires.

you never know

If you take the slide off and then turn it upside down, try moving the fire selector and see if you can see (I think) triger reset part move. It should move from hard up against the edge of the slide towards the centre of the slide as you operate the selector.
