Best Extended Scope Rail for AR

If you mount a large, high-magnification scope on an AR15, AR10, or AR-based space-gun, you’ll need to set the scope well forward to allow proper eye relief while retaining normal length of pull. (Buttstock extensions will move you far enough away from the rear eyepiece, but then you may have to reach too far to the trigger.)

Robert Whitley, who regularly uses scoped ARs and spaceguns, recommends the GS-1 extended rail from GG&G. This allows you to put the front scope ring out front of the receiver. The rail fits any flat-topped AR receiver with a picatinny mount, and retails for $89.95 at 6mmAR.com and other vendors.
