RPA Systems Ltd Barrel Manufacturing Machinery now in place and ready for your orders!

We have recently taken delivery of the latest state of the art barrel manufacturing machinery from both the USA and Germany.

This machinery enables us to achieve extraordinary precision and tolerances.

Our new Rifling Machine is now set up to rifle all the standard barrels and twists. As we develop in this sector, we will continue to add Rifling Buttons to our capability to fulfil all the usual (and in some cases, unusual) twists and grooves. Currently we have all the traditional twists and groves for .243; .270 Winchester; .280 Remington; 7mm; 308; 338; and 50cal.

We have additionally purchased the latest Gun Drill Reamer and Stress Relieving Oven. This ensures that we enter the market capable of manufacturing to the same high standards (hopefully better due to the technological advances of the machinery and air gauging) of our excellent American cousins Messrs Bartlein, Lilja, Krieger etc; to say nothing of Lothar Walther.

Finally, we have taken delivery of our own Nitriding Furnace. This will enable us to provide rock hard finishes to our existing RPA components. We are in the final stages of signing off various Nitriding enhancements to our new barrels (both on the inside and outside).

For your high quality UK made rifle barrels please call us on +44 (0) 845 880 3222 or email for a quote. Please note that at the moment we can only produce the following Barrel Blanks calibers: .308 .338 .50cal with further barrel versions to follow in early  2017.

We are delighted to announce our latest product. The RPA Scope Mount
