The EGW AR Extendariser Picatinny rail is a precision 20 MOA riser mount designed to give your AR-platform rifle a higher, more comfortable sight picture and faster target acquisition. By raising your optic approximately 0.600" above the receiver rail, this riser eliminates the need for extra-high rings on most builds while keeping your head more naturally aligned with the stock. The 20 MOA angle compensation is machined into the top of the mount, so the added height doesn't force you to dial up your scope's elevation to the point of wasting adjustment travel.
Built from 6061 T6 aluminum billet and finished with CNC precision, the Extendariser delivers 7" of usable Picatinny rail—that's 1.5" more mounting length than the receiver alone provides—so you've got room to dial in your eye relief exactly where you want it. The underside is relieved to clear most handguards without interference. Three heavy-duty steel cross-bolts clamp it solidly to your receiver rail, preventing shift under recoil, while the seamless fit matches your rifle's profile.
The full MIL-STD 1913 Picatinny slot spacing accepts any standard Picatinny or Weaver-style scope rings, giving you flexibility in optics choice and the ability to adjust your setup as your needs change. Whether you're building a precision rifle, a hunting AR, or refining an existing setup, this riser gives you the geometry you want without the compromise.

Frequently Asked Questions
Will this riser work with my current scope rings?
Yes, the Extendariser accepts both Picatinny and Weaver-style scope rings, so you can use your existing rings or choose new ones that match your setup.
Does the 20 MOA angle affect my zero?
The 20 MOA angle is compensated into the mount design, so it doesn't force you to use excessive elevation adjustment on your scope. This preserves your scope's vertical adjustment range for actual shooting correction.
Will this clear my handguard?
The underside of the extension is relieved to provide clearance over most AR handguards, but fit depends on your specific handguard design. Verify your handguard profile before installation.
How secure is the attachment to my receiver?
Three heavy-duty steel cross-bolts clamp the mount directly to the receiver rail, providing a secure hold designed to prevent movement under recoil.
