SWFA 16 x 42 Tactical Rifle Scope with heavy duty Tactical Rings. This is a NATO Spec shockproof, waterproof, and fog proof scope with a 30mm tube. It is rated for up to a .50 cal. it has a mil-dot reticle and is in excellent condition. This is a great scope for the money. These are a very under-rated scope due to the low price point. I just have no use for it. I have purchased it new and it has been well cared for. $325 OBO for scope and rings. Will consider trades.
