Winchester 1300 defender in that pic?
If it is, I don't know how in the hell you deal with that side saddle. Mine kept on spinning off cause there's only one nut that holds it into place... I finally just got rid of it and used the stock reciever pin.
I have the same stock, and I absolutley love it, but every time I want to clean the gun I need to rotate the pistol grip by loosening the allen screw to get the trigger group out..
I think what I'm trying to say is, nice gun!
Do you have any other pictures of the light? I too am looking for something similar without spending 250$...
