"The Arcalock 14.25″ Universal Weight-Tunable Rail is a brilliant way to fine-tune your rifle’s balance while gaining all the benefits of the Arcalock system. With five removable weights, you can shift the centre of gravity exactly where you want it for barricade work or prone stability. It’s a subtle upgrade that makes a surprisingly big difference to how your rifle handles under match pressure." – Thomas.
