Best Scopes for .450 Bushmaster in 2026

For the best overall scope for .450 Bushmaster, it is hard to beat a quality 1-6x or 2-7x variable from a manufacturer with a proven track record on hard-recoiling platforms. Look at the Vortex Strike Eagle 1-6x24, the Leupold VX-Freedom 2-7x33, or the Burris Fullfield E1 2-7x35 as strong starting points. All three sit in the $200–$400 price band, carry lifetime or no-fault warranties, and are built on one-piece tubes with internal construction designed to withstand sharp recoil impulses. The ideal overall pick combines a generous eye relief of at least 3.5 inches, a simple and fast reticle like a duplex or illuminated BDC, and enough low-end magnification to allow quick target acquisition at the distances where most US whitetail are actually taken — typically well under 150 yards from a stand. You do not need 18x for a 200-yard cartridge; you need reliability and speed.

For the best budget option that will actually hold zero, you need to be realistic about what "budget" means on a cartridge this punishing. Below roughly $150, the odds of finding a scope with internal construction robust enough for sustained .450 Bushmaster use drop sharply. The Vortex Crossfire II 2-7x32, which typically falls in the $130–$180 range, is one of the few genuinely budget-tier scopes that earns a recommendation here, largely because Vortex's VIP warranty means a no-questions replacement if recoil does eventually win. The Primary Arms 1-6x24 SFP with an ACSS reticle is another option in the $200–$280 band that punches above its weight in durability. Avoid ultra-cheap scopes marketed for rimfire or airgun use — their turret mechanisms and erector tube springs are simply not designed for this level of punishment, and a lost zero in the field is worse than not having a scope at all.

For an AR-15 platform .450 Bushmaster, your mounting situation is as good as it gets: the flat-top Picatinny rail accepts standard rings or a one-piece cantilever mount, and eye relief positioning is easy to adjust with the infinite rail positions available. This makes low-power variables like a 1-4x or 1-6x an ideal match, giving you true-1x for fast close-range work and enough top-end magnification for any shot inside 250 yards. A lightweight scope matters here because AR-platform .450 rifles are often already heavy due to their thick barrels and heavy bolts. Consider scopes in the 14–18 oz range to keep the total package manageable. A red-dot or holographic sight is a viable alternative if your shots are all inside 100 yards, but most hunters benefit from at least some magnification for positive target identification at dawn and dusk.

For a bolt-action .450 Bushmaster — especially on popular platforms like the Ruger American Ranch or Savage 110 — scope mounting requires a bit more planning. These rifles typically ship without a Picatinny rail, so you may need separate bases and rings matched to the receiver. The Ruger American uses a proprietary rail system, while the Savage 110 uses the Savage AccuTrigger-compatible base pattern. A 2-7x or 3-9x variable in the 1-inch tube format is the classic bolt-action hunting scope profile, and it works beautifully on these rifles for the .450 Bushmaster's effective envelope. The Leupold VX-Freedom 3-9x40 and the Burris Fullfield IV 2.5-10x42 are both strong choices in the $250–$450 band. Because bolt guns tend to have slightly shorter length-of-pull than AR stocks, pay extra attention to your eye relief measurement once the scope is mounted — position the scope as far forward in the rings as possible while maintaining a full field of view.

Eye relief matters more on a .450 Bushmaster than magnification does, and this point deserves its own emphasis. Scope bite — the ocular lens housing striking your eyebrow under recoil — is a genuine hazard with this cartridge, not a theoretical concern. The .450 Bushmaster generates recoil energy in the neighborhood of 20–25 ft-lbs depending on rifle weight and load, comparable to many magnum rifle cartridges. You want a minimum of 3.5 inches of eye relief at your most-used magnification setting, and 4 inches or more is preferable if your shooting position allows it. Many scopes list eye relief at the lowest magnification, where it is longest; verify the spec at the magnification you will actually use in the field. If you are choosing between a scope with spectacular glass quality but 3 inches of eye relief and a scope with good glass and 4 inches, choose the longer eye relief every time. A black eye on opening morning is not just painful — it causes a flinch that ruins your follow-up shot and can create a lasting bad habit.
