EGW
The EGW AR Extendariser Picatinny Rail is a precision-machined aluminum riser mount engineered to elevate your optic for a more natural shooting position and faster target acquisition on AR-platform rifles. If you've ever felt cramped behind a low-mounted scope or found yourself craning your neck to get a proper sight picture, this rail extension solves that problem without forcing you into overbuilt rings that complicate your setup.
Built from 6061 T6 aluminum billet and CNC-machined for precision, the Extendariser adds approximately 0.600 inches of height while maintaining a clean, integrated look that matches your receiver profile. The real engineering trick here is the 20 MOA top-surface angle, which compensates for the added height and minimizes point-of-impact shift—so you're not chasing your zero across the bench. Three heavy-duty steel cross-bolts clamp to your receiver rail with the rigidity needed to stay put under recoil; the underside is relieved for handguard clearance on most builds.
The mount provides 7 inches of usable Picatinny-standard mounting length—that's 1.5 inches more than your receiver rail alone—giving you genuine flexibility in eye relief and optic choice. It accepts both Picatinny and Weaver-style scope rings, so you're not locked into one ring ecosystem. Whether you're setting up a precision rifle, a duty carbine, or a hunting AR, this rail eliminates the need for extra-high rings in most situations, keeping your build cleaner and your cost lower.
| Material | 6061 T6 aluminum billet, CNC-machined |
| Height Increase | Approximately 0.600" |
| Mounting Surface Angle | 20 MOA |
| Usable Mounting Length | 7 inches Picatinny rail |
| Clamping Method | Three heavy-duty steel cross-bolts |
| Ring Compatibility | Picatinny and Weaver-style |
| Mounting Standard | MIL-STD 1913 Picatinny slot-and-rail spacing |
The 20 MOA angle built into the top surface is designed to compensate for the added height and minimize shift to your point of impact. You'll still want to verify your zero on the range, but the engineering here prevents the dramatic zero shift you'd get from adding height without that compensation.
The Extendariser accepts both Picatinny and Weaver-style scope rings, so compatibility is broad. If your rings fit a standard Picatinny rail, they'll mount to this extension.
The underside of the extension is relieved to provide clearance over most handguards, but handguard profiles vary. Verify clearance with your specific setup before finalizing your build.
The Extendariser provides 7 inches of usable Picatinny mounting length—that's 1.5 inches more than your receiver rail alone—allowing you to adjust eye relief and optic position with genuine flexibility.
