The Burris AR-P.E.P.R. 34mm Picatinny Fixed Scope Mount (410345) is a one-piece cantilever scope mount for 34mm scope tubes, holding the optic at a 1.35in (34.3 mm) optical centreline over any Picatinny rail. P.E.P.R. stands for Proper Eye Position Ready — the cantilever pushes the scope up to 2 inches (51 mm) forward so you can set correct eye relief on a flat-top receiver, where a receiver-mounted ring set would sit too far back. It also has 20 MOA of cant built in, giving you extra elevation for long-range work without a separate tapered base.
It uses cross-bolt clamps for a permanent, no-fuss fit, and it 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. It weighs 6.9 oz (196 g).

Frequently Asked Questions
What does P.E.P.R. mean on the Burris AR-P.E.P.R. 410345?
Proper Eye Position Ready. The cantilever moves the scope forward — up to 2 inches (51 mm) — so you can set correct eye relief on a flat-top rifle instead of being stuck with wherever the receiver puts the rings.
Is the Burris AR-P.E.P.R. 410345 the fixed or quick-detach version?
410345 is the Fixed 34mm model. It clamps on with cross-bolts and is meant to stay put.
What scope tube diameter does the Burris AR-P.E.P.R. 410345 fit?
It has integral 34mm rings, so it fits scopes with a 34mm main tube only. Burris makes the AR-P.E.P.R. in 1 Inch, 30mm and 34mm.
How high does the Burris AR-P.E.P.R. 410345 hold the scope?
The optical centreline sits 1.35in (34.3 mm) above the rail, measured from the rail surface to the centre of the scope tube.
Can I fit accessories on top of the Burris AR-P.E.P.R.?
Yes. Two sets of ring tops are supplied — smooth for a clean build, and Picatinny-slotted for mounting a small accessory above the scope.
What torque should I use on the Burris AR-P.E.P.R.?
Burris specifies the cross-bolts to 65 in-lb (7.3 Nm) first, then the ring tops to 20 in-lb (2.3 Nm), alternating screws in an even pattern.
What does the 20 MOA cant on the Burris AR-P.E.P.R. 410345 do?
It tilts the scope forward by 20 MOA relative to the bore, so more of the scope's elevation travel is left for dialling up at distance. 410345 is the model in this range that has it built in.
