The Warne 45 degree offset Picatinny side mount adapter mounts to standard Picatinny rails on your rifle or handguard, giving you a clean 45-degree mounting platform for red dots, backup sights, weapon lights, lasers, or other tactical accessories. It's built from precision aluminum and designed for flat-top MSRs and other modern tactical rifles where you need secondary optics or gear positioned at an angle that won't block your primary sight picture.
Installation is straightforward—no gunsmithing required. The side-mounted 45-degree angle keeps your red dot or backup iron sight positioned to co-witness with your main optic without competing for your line of sight. This offset design is popular for competition shooters, tactical trainers, and hunters who run multiple aiming solutions on the same gun.
Warne engineered this mount with two cutout sections to save weight without sacrificing strength, and the side rails feature four cross slots total for flexible mounting options. Whether you're setting up a duty rifle, a competition platform, or a hunting gun with layered backup systems, this aluminum adapter gives you solid, no-fuss Picatinny mounting where you need it.

Frequently Asked Questions
What rifles and rails will this mount fit?
The Warne A645 is designed for flat-top MSRs and any firearm with a Picatinny-style rail on the upper receiver or handguard. It bolts directly to standard Picatinny slots with no modifications needed.
Can I use this as a backup sight mount?
Yes. The 45-degree offset position allows your backup sight to co-witness with your primary optic mounted on a top rail without blocking your main sight picture. It's a common setup for redundant aiming systems.
What accessories can mount to this adapter?
The four cross slots on the side rails accommodate red dots, backup iron sights, weapon-mounted lights, lasers, slings, or any accessory with Picatinny attachment points.
Will this work on my handguard?
Yes. If your handguard has a Picatinny rail, the Warne side mount can be installed there, giving you a secondary mounting option that doesn't interfere with your primary optic.
