Does anyone know what size rollpin does the BC 1.5 take?





Thanks

I just did mine about a month ago and think I used either 3/32 or 1/8 . Not a roll pin I used steel rod . I'll see if I can find what I used later and confirm size .

Thanks, I watched the ITS Tactical video and confirm that the the rod should be tool steel and not a roll pin.  Looks like they used the same drill bit, cut it to size, and used it to permanently attach the BC 1.5 to the barrel which is a great idea and won't allow you to remove the BC using ordinary hand tools.
