Same idea as the Crossfire II, but with clearer, sharper glass for a little more money. The linked version has a plain crosshair with no extra hash marks.
A good first low-power zoom scope for an AR-15. At 1x it works almost like a red dot for close shots, and you can zoom to 8x for farther targets. About 9% of AR builds we tracked use it.
The most popular AR-15 scope on GunPartPicker, on about 17% of builds. Like the Strike Eagle, it works like a red dot at 1x and zooms to 6x, and it costs less.
The cheapest first-focal-plane scope from a major brand. In a first-focal-plane scope, the aiming marks grow and shrink as you zoom, so the holdover marks stay accurate at any zoom setting.
Vortex's best-value long-range scope. It has a lot of up-and-down adjustment, enough to dial for very long shots, and its aiming marks stay accurate at any zoom.
It zooms from 4.5x to 27x, its aiming marks stay accurate at every zoom setting, and the reticle lights up for low light. All that for under $500.
Our best overall hunting scope. It's light, the glass is bright at dawn and dusk, and it's made in the USA. The custom dial lets you turn the knob to a marked yardage instead of guessing holdover.
Our best overall long-range pick under $1,000. It's built to dial for distance and return to zero reliably, shot after shot.
The best budget long-range scope whose aiming marks stay accurate at any zoom. It usually sells for about $659, which puts it in this tier.
It uses Primary Arms' ACSS Athena reticle, a crosshair with built-in marks for holding over at distance and leading moving targets.
Our best overall scope for long-range precision rifle competition. The 2025 Precision Rifle Series champion, Morgun King, used one.
Vortex's top-of-the-line alternative to the Mark 5HD. It had the clearest glass in GunsAmerica's testing.
