The Meostar 1-4x22 ZD Tactical KDot RD has a 30mm maintube diameter, with its reticle placed in the rear focal plane (in front of the eyepiece) to maintain its virtual size throughout the entire magnification range. Targeting smaller game at longer distances is quite easy with the reticle location in the rear focal plane.
The Meostar 1-4x22 ZD Tactical KDot RD is a versatile scope well suited for dangerous game rifles, slug guns, as well as rimfire and small/short-distance target/varmint shooting applications. A favorite of 3 gun competitors, you too will see the beauty of this scope the minute you look through it.
