Pirate:

Do you think your setup will go into one of PBB's SA bolt conversions also?

Thanks,

If you can drill out the stud in the back it will.


I am really interested in these. When you say drill out the feed stud, what diam hole are we talking about? Is this just for the fp, or is this for the tube extension on the wedge. Also, it this new design a 2 piece fp? Pictures are always a help :mrgreen:

also, anyone here running one of these yet? Just wondering how well they are working?

you need to drill the feed stud out with a 3/8" bit so the striker tube can go through, it sticks out the rear. the entire wedge / tube assemblt is supported on both ends. it totally eliminates binding

here is a video, I have fired almost 1k rounds in 8mm and 308 developing this setup.

Pirates set up is flawless in my mg42, no hiccups at all and hit very hard at the primer.

Pirate-I got the new bolt wedge-Thank you,another nice piece of work.Do I have to do any modification to your set-up? And will the old firing pin work in this? Stupid questions,but my stuff is packed away and I want to make sure I have all I need before I dig it out.Thanks. ---bil

I have a Pbb converted bolt. I think the feed stud is pressed in with a roller on top. If I drill with a 3/8" bit, it will completely go through the feed stud. I'm going to have to rethink this.
