The Burris AR-P.E.P.R. 1 Inch Picatinny Fixed Scope Mount is a one-piece cantilever scope mount for 1 Inch tubes, holding the optic at a 1.50in optical centreline over any Picatinny rail. P.E.P.R. stands for Proper Eye Position Ready — the cantilever pushes the scope forward so you can set correct eye relief on an AR-pattern rifle, where a receiver-mounted ring set would sit too far back.
It uses cross-bolt clamps for a permanent, no-fuss fit, and ships with two sets of ring tops: smooth tops for a clean build, and Picatinny-slotted tops if you want to mount a small accessory above the scope. Burris quotes up to 2 inches of forward scope positioning.

Frequently Asked Questions
What does P.E.P.R. mean?
Proper Eye Position Ready. The cantilever moves the scope forward — up to 2 inches — so you can set correct eye relief on an AR-pattern rifle instead of being stuck with wherever the receiver puts it.
Is this the fixed version?
Yes — 410343 is the Fixed 1 Inch model. It clamps on with cross-bolts and is meant to stay put.
Can I fit accessories on top?
Yes. Two sets of ring tops are supplied — smooth, and Picatinny-slotted for mounting a small accessory above the scope.
What torque should I use?
Burris specifies cross-bolts to 65 in-lb first, then ring tops to 20 in-lb, alternating screws in an even pattern.
