The Burris P.E.P.R. mount has become the absolute go-to mount of choice for an incredibly solid, long-lasting cantilever mount. It makes mounting an optic to an AR-style rifle very easy, providing the necessary clearance and adding as much as 2 inches of forward scope positioning. It also ensures proper eye placement. PEPR stands for "Proper Eye Position Ready", pronounced PEPPER MOUNT. They are available in 1 inch, 30mm and 34mm sizes. Quick-detach (QD) models are available in 1 inch and 30mm sizes. The 34mm size is designed with 20 MOA of built-in cantilever.
