Hi guys I'm after some advice on removing the reg on this rifle I have tried needle nose pliers and cannot get it unscrewed so any advice on how to remove this would be great. Also I'm removing it has the shot curves gone all over the place has it was extremely consistent so any thoughts on how I can remedy this through the reg would be a great help and also how to get the best Shot count and consistency. So if anyone has had this problem and has sorted it out please leave a comment on how I can go about sorting mine out thanks guys.The guage is the one on the bottom of stock on mine not on the side like in this pic.
