This Talley Piccatinny Base is compatible with Bergara’s B14, Christensen Arms Mesa and Ridgeline series, and Remington 700 rifles. The installation of this Picatinny base enables the mounting of a wide range of rings and scopes from tactical to traditional. These rails were manufactured in the USA and constructed out of grade 7000 alloy and given a hard anodized finish for durability and long service life. The rail features an integrated anti-cant bubble level which helps ensure your rifle is perfectly level, and eliminates the issues caused by an improperly mounted separate bubble level device. These rails come in 20 MOA and are available in short and long action.
