PO 4x38 FED Weapon Rifle Scope w/ Duplex Reticle. Kalinka Optics Warehouse® carries only the finest rifle scopes. We recently uncovered a batch of these scopes from one of the Soviet Union's most famous military factories, FED, in a Ukrainian military warehouse. All the units have been thoroughly tested and are available in limited quantities. This is the nicest batch of Soviet-designed rifle scopes we have had and were made on updated Soviet designs from the German Zeiss-Jena factory. These are rare and sought after and it is unlikely we'll have more in the future. They are extremely well-built and rugged, have very clear glass and are suitable for military, law enforcement and sporting use. The scope allows easy and precise aiming without parallax and as you would expect in a superior scope there is no grid floating when you move your eye so you always stay lined up. The adjustable eyepiece diopiter ring allows you to focus for perfect clarity and has a setting ring for fixing the diopiter in place. The reticle is simple but extremely effective and useful, it can be used effectively with any caliber of weapon. The FED series has magnesium alloy bodies, is nitrogen purged and has fully multi-coated optics. They are waterproof and can be used in a variety of climate conditions. This scope has a one inch tube and is easily mountable on any weapon that takes Weaver-style rings, Ruger rings, Dovetail rings or other one inch rings. Kalinka Optics Warehouse® carries a broad selection of mounting platforms, rings and other accessories. Take a look through our accessories section for mounting choices. We really love the quality of these scopes; it comes with everything shown in the pictures.
