The best way to sort this out is shooting at pattern plates or paper targets to see where the gun shoots and adjust as needed. If you raise the stock you shoot higher and lower the stock and you shoot lower.
This is because a shotgun shoots where you are looking down the rib. Please bear in mind when you increasing the stock length will put your face lower than before in relation to the guns rib ,and you will probably need to adjust your stock height with the shims as per the manual. įrom about 2014 the stocks were increased to 13.5" and with the 1" butt pad they are 14.5" and can be increased to 15.1", or with the bigger butt pad will go to 15.4" length of pull. Early guns from approximately 2004 to 2014 had 13" stocks and with the 1" butt pad making it 14" can be increased to 14.6" length of pull or with the longer 1.3" butt pad they can be increased to 14.9". 6" or 16mm to the length and can be used with either the 1" or 1.3" butt pad, and is simple to fit and remove when needed.
The spacer is made of rubber and designed to have the same quality, look and feel as the other rubber parts on your Benelli., My spacer is the result and I believe if you have found your gun too short, you will shoot better with the spacer fitted as I have, because when your gun fits you, you shoot better.
I did try and find a way to increase the length of my gun by searching online and in shops and there was nothing availableīecause of this I decided to try and make something for my gun which would then be useful to other people. I am a big Benelli fan, but I have found them too short in the stock to fit properly and after speaking to Benelli dealers they all agreed that it was a problem.
