About
What it is, and why it matters
The Bushmaster BOAR is a .450 Bushmaster AR-15-pattern hunting rifle purpose-built for big game across North America, particularly in states that restrict deer hunting to straight-wall rifle cartridges. It uses a 20-inch 1:24-twist barrel, a free-float BFI 15-inch M-LOK handguard, a DM2S two-stage trigger, and a Magpul UBR Gen2 collapsible stock, feeding from a 5-round single-stack .450 magazine. It joins Bushmaster's longstanding .450 lineage with a modern, hunting-focused build.
Named for the wild hogs and big game it was built to drop, the BOAR leans into the .450 Bushmaster's reputation as a brush-country 'thumper' - a hard-hitting straight-wall cartridge that turned the AR-15 into a legal and lethal deer rifle across the American Midwest.
MSRP approximately $1,184. Chambered in .450 Bushmaster. Distinct from the legacy .450 Bushmaster XM-15 E2S entry; the BOAR is a modern free-float, Magpul-equipped hunting configuration.

Trajectory
What the round does downrange
Solved from the muzzle figures and the bullet. The dashed rule is the effective range on the record, and the crosses are the steps the solver returned.
No load solved for this record yetThe flight path is computed from a cartridge and a bullet. This record has no ammunition filed against its chambering, so there is nothing to solve.
