Of course, a.45-caliber, 250-grain bullet leaving the barrel at 2,200 fps is a huge performance improvement over the 5.56 NATO’s comparatively small 55-grain bullet exiting the barrel at 3,200 fps. Few people hunted with an AR-style rifle when the.450 Bushmaster was launched.

Now .450 Bushmaster has become a staple of the gun industry and has become synomous with excellence, accuracy, and skill in all sorts of shooting conditions. Some of the best rifles in the world rely on the .450 Bushmaster.

The length of the casing is 1.70 inches. It utilizes bullets with a diameter of.452 inches, similar to those used in.45 caliber pistols, rather than conventional bullets. Bullets with a diameter of 458 inches. The entire length of the loaded cartridge is 2.250 inches, and the casing accepts tiny rifle primers.

In a industry filled with sleek, quick, slender cartridges vying to push the AR-15’s range and mechanical precision to new heights, the .450 Bushmaster may seem to be a bit different– after all, it’s a huge, slow-moving, straight-walled cartridge that excels inside 200 yards. However, those same characteristics make it ideal for hunters in the Midwest who can’t legally hunt with bottlenecked cartridges, as well as those searching for a drop-in upper that will allow them to bag wild boar, elk, moose, and even bears without breaking the budget.

Check Price on Amazon

At 14x and 100 yards, the view is barely 7.85 feet high and broad. The height and width of 7.85 feet is rather narrow.

This is, without a doubt, a long-range scope. The fact that a long-distance precise shot at various ranges has never been more available has stuck out the most.

Rather than spending a lot of money on a scope, a spotting sight, and a rangefinder, you can now start shooting great distances with only the scope.

It enables a buddy to jump right in and gain confidence fast, but it also resets the learning curve when they switch to a sight with a simpler reticle.

This scope does a fantastic job at what it does. The picture is clear and crisp even at maximum magnification, and the light transmission is excellent. When compensating for wind, .1 mil adjustment rotation on the turrets passes the box test.


  • Reitcle is FFP, which means it remains true to size and gets smaller as you zoom out and larger as you zoom in
  • FFP is typically not seen in budget scopes but it is available here
  • Glass and light transmission at 14x
  • .1 Mil turret adjustment clicks


  • Not as good at short ranges as it is at long ranges
  • Only fog resistent but not fogprrof (there is a difference)


This is one heck of a long-range scope for your Bushmaster.
