A Modern Classic With an unrivalled tournament pedigree and years of field use behind it, the Sterling is without a doubt, The classic pump gun. Now manufactured on our state of the art CNC machines, the Sterling has been modernised with build quality in mind. With updated internals, the Sterling now delivers unprecedented performance and reliability. The Sterling is back, better than ever...The Sterling series of pump guns (previously manufactured by Proline and Lada Sterling Limited) was taken over by Arrow Precision Limited in February of 1998. Since that time, we at Arrow Precision have re-evaluated every aspect of the design and have made some changes that we believe bring the gun right up to date, and once again make it the finest pump gun in the world. As in previous years, the gun is produced in two versions, The Bronze,for use in the site rental environment and STP fortournament use. A list of factory upgrades are available here.
