I've got a Bushy M4 upper And I can't see a line where the break and barrel meet . There is just a smooth transition ,But I shined a light in the end of the break and can see threads .Also I can't find a spot for it to be pinned But there are two flat spots on the left and right side of the break . I'm sure if I grind on one or the other I should be able to find something right ? Also where can I find a FSB with a Bayo lug ? This is all I need to complete My noban I already got a RRA 6 pos stock ! Thanks Jeremy

The flat spots on your FS are for a wrench. Do NOT grind these down, you will not be able to get it off. Just forward of these there should be a spot that hopefully is discolored. This is where the pin is welded. That is where you need to gind it down a little to free the pin and then unscrew the FS. If you do a search you should be able to located several threads on this topic. Some members have posted another way to remove a FS which involves cutting into the FS from the bore toward the upper and then separating the halves. I would just look for the spot that is reblued and go from ther.


As for the new FSB, probably Bushmaster would be the best choice to make replacement the easiest.
