Lancer Tactical 2.5-10x40 Outdoor Hunting Sport IR Scope, Black

You want to engage at distance but you don't want to be locked into a sniper optic. The 2.5–10x range on this scope covers the gap. At 2.5x you've still got a usable field of view for closer work; at 10x you can pick off targets at the end of a long outdoor lane. It's the kind of optic that makes a DMR-role build viable without committing to a fixed-power rifle scope.

Optics. The 40mm objective lens is a practical mid-size: gathers decent light without the length and weight of a 50mm tube.

Size and weight. At 198mm long and about 1.21 lbs, it's light enough to not shift your rifle's balance forward — a real consideration when you're scanning a field or moving between positions all day.

Before you buy. The scope ships by itself. Mounting rings, a 1-inch or Picatinny scope base, and any sunshade are not included — you'll need to pick those up based on your rail and tube diameter. And if you play mostly tight CQB where you're engaging inside 30 feet, a 2.5–10x is more optic than that game calls for. A red dot is faster in those lanes.
