"The Black Art", as it has been referred to over time, refers to altering the barrels of a side-by-side rifle by heating and repositioning them in a specially designed jig in order to achieve the required grouping at a set distance i.e. 65 yards to 100 yards.

I have been regulating rifles for 20 years for many of the traditional English gun and rifle makers, including Rigby & Co, J. Roberts & Sons, James Purdey & Sons and Wesley Richards & Co to name a few.

All regulating is available from calibers .22 to .700, and even 4 bore.
