Ok guys i posted this at another forums and so far im not getting any replys. I hope the pack can help me out here.

Ok i want to add a sling to my shottie. The only thing is i don't want to attach the sling to the end of the choke tube cap. If i do that then i wont be able to use the bayo lug.

Now i noitced there is a hole at the back of the bayo lug. Its threaded and looks like it can except a stud to allow a swivel.

Does any1 know where i can get this stud? ( not sure what its called )

Ive been searching for hours now with no luck. I know the 590A1 models come with it already but not the reg 590.
