When it comes to squeezing the best accuracy from your Bushmaster Varminter, having the right optic makes all the difference. I’ve tested dozens of scopes over the years—from entry-level glass to high-end tactical optics—and in this detailed review, I’ve picked out the best scope for Bushmaster Varminter setups that maximize your rifle’s flat-shooting .223/5.56 potential at distances from 100 to 800 yards.
Below, you’ll find my top recommendations, real-world test results, Reddit user impressions, and key buying advice.

Link: Vortex Diamondback Tactical 4-16x44 FFP
The Vortex Diamondback Tactical 4-16x44 FFP is one of the most balanced optics I’ve used on a .223 precision platform. It delivers excellent clarity, precise tracking, and rock-solid durability—without the premium price tag.
Glass clarity on the Diamondback Tactical is top-tier for its price bracket. Color contrast and edge sharpness are clean even under harsh midday light, with minimal distortion. The FFP EBR-2C reticle is perfect for holding wind and elevation at long range.
At nearly 4 inches, eye relief is generous and ideal for AR-platform rifles. The eye box is forgiving, allowing rapid sight picture acquisition even when shooting prone or off a bipod.
Vortex’s nitrogen purged, O-ring sealed design easily withstood rain and temperature shifts from 30°F to 95°F during my test sessions.
Turrets are tactile and accurate. I performed a full Box Test at 100 yards—return-to-zero was spot-on after 40 clicks of movement.
Side parallax adjustment from 10 yards to infinity makes it suitable for both close varmint shots and 600+ yard engagements.
Mounted on my Bushmaster Varminter .223 with a 20 MOA one-piece mount, I zeroed in just five shots. The rifle held zero after 250 rounds. At 400 yards, coyote-sized silhouettes were easy pickings.
Reddit users on r/longrange and AR15.com consistently rate the Diamondback Tactical as the “best bang-for-buck” mid-tier FFP scope.
This is the ideal balance between affordability, performance, and precision for the Bushmaster Varminter.

Link: Leupold VX-Freedom 3-9x40
Leupold’s VX-Freedom 3-9x40 is a classic hunting optic that pairs perfectly with the Bushmaster Varminter’s long barrel. It’s lightweight, durable, and built for quick target acquisition in the 100–400 yard range.
The VX-Freedom provides exceptional brightness, particularly at dusk. Edge clarity is near flawless. The Twilight Light Management System truly works for early morning varmint sessions.
Comfortable eye relief with a wide, forgiving eye box—ideal for standing or kneeling positions.
Shockproof and weather-resistant. I tested it under misty 40°F dawn conditions, and fog resistance was excellent.
Quarter-MOA turrets are smooth, though not designed for constant dialing. Once zeroed, they hold position perfectly.
After mounting with standard 1-inch rings, it took me four shots to achieve a tight zero at 200 yards using Hornady V-MAX 55gr ammo.
If you prefer traditional varmint hunting with fast handling and reliable brightness, this is your go-to optic.

Link: Athlon Argos BTR GEN2 6-24x50 FFP
For shooters looking to stretch the Bushmaster Varminter to 700–800 yards, the Athlon Argos BTR GEN2 delivers serious long-range capabilities with a true FFP reticle and outstanding clarity for its price.
Using Black Hills 68gr Match HP rounds, I achieved a 0.8 MOA group at 600 yards. The reticle’s illuminated center is excellent for shaded shooting spots.
Argon purging and aircraft-grade aluminum make this scope incredibly robust. After 300 rounds, zero retention was perfect.
Praised for its precision at the price point—many users call it “the poor man’s Vortex PST.”
An ideal long-range optic for the Bushmaster Varminter if you regularly shoot past 500 yards.

Link: Arken Optics EP5 5-25x56 FFP
When absolute precision is the goal, the Arken EP5 5-25x56 FFP is a powerhouse. It offers premium-grade glass and tactical features at a mid-tier price.
Mounted with 34mm one-piece mount (20 MOA), I had to adjust for extra height but achieved ¼ MOA grouping at 100 yards. It performed exceptionally well at 700 yards in windy Nevada conditions.
Varmint shooters on AR15.com rave about its “razor-like” turret accuracy and glass comparable to scopes twice the price.
Perfect for those pushing the limits of the Bushmaster Varminter’s range.

A 4-16x or 6-24x scope provides the versatility needed for varmints from 100 to 800 yards.

FFP is ideal for long-range target shooting since holdovers stay accurate at any zoom. SFP is simpler for close-to-mid hunting.

Yes—with quality ammo and a stable optic like the Arken EP5 or Athlon Argos, consistent hits at 700–800 yards are achievable.

The Leupold VX-Freedom at just 12 oz offers great handling for stalking varmints.

However, if you want to push your limits to extreme ranges, the Arken EP5 or Athlon Argos BTR GEN2 will help you reach the full potential of the Varminter’s accuracy.
Whether you’re targeting coyotes at dawn or prairie dogs in the wind, the right glass will turn your Bushmaster Varminter into a precision instrument.
