Arken Optics Outrider 3-18×50 SFP Riflescope – 30mm Tube

The Arken Optics Outrider 3-18×50 is Arken’s first all-round hunting scope, built for everything from close, quick shots in cover through to longer shots across open ground. The 3-18x magnification range and large 50 mm objective pair with Japanese HD glass and fully multi-coated optics, which Arken rates at over 90% light transmission for a bright, detailed image in low light.

Choose between two second focal plane reticles: the illuminated FDR with a fibre-optic red aiming point, or the non-illuminated DLR with bold outer posts and a fine centre. Both stay the same size throughout the magnification range, and a side-focus parallax wheel lets you set focus from 10 yards (9 m) to infinity.
