It was easy with the dremil, my advice is go slowly and where you take the biggest bit of material out you do need to make it a curve not flat. I stopped at flat and it didn't work, then proceeded to radius it out and it now works a charm. Sorry no pics of the bolt stop mod.
Whilst it was apart I cleaned the trigger group and polished the reciever and the top of the bolt.
It feels smoother dunno if it'll make any difference but it can't hurt, it had no trouble cycling cci subs before, it does feel a lot smoother now.
