The Proof House

Gun Proof since 1637

"The Proof House rigorously tests firearms through the process of proving to ensure their safety and durability. This gun proof process safeguards users and upholds the integrity of British gunmaking. Established by Royal Charter on 14th March 1637, we have set global standards for nearly 400 years."

~ David Miles, Proof Master

Advanced testing methods and bespoke proof test fixtures developed in-house, enhance the safety, consistency, and efficiency of gun proof. These new fixtures ensure that guns remain undamaged during the proving process, whether tested in the ‘white’ or fully stocked.

State of the art and fully tailored services based on individual requirements, but always grounded in safety, quality assurance, traceability, accuracy and consistency.
