## Description

The GLFA AR-15 in .450 Bushmaster is a modern sporting rifle built for hunters and shooters who want serious big-bore performance in an AR platform. The .450 Bushmaster caliber delivers substantial stopping power with manageable recoil, and the 18-inch barrel gives it enough velocity to make the most of that cartridge.

### Detailed Features
The upper and lower receivers are aluminum (7075 for the frame, 6061 for the handguard) keeping overall weight at 6.4 lbs. The muzzle brake redirects gases forward at a six-degree angle, which noticeably reduces muzzle rise during rapid fire. The 15.25-inch full Picatinny rail handguard gives plenty of room for optics mounts, lights, or other accessories.

At 5-round capacity, this rifle is configured to comply with states that restrict magazine size for hunting, which is a practical consideration for the .450 BM's primary use case. The OD Green Cerakote finish holds up well in wet or rough field conditions.

## What Customers Say

*AI-generated insights from customer reviews*

Owners of the GLFA AR-15 .450 Bushmaster generally like the caliber choice. The .450 BM's stopping power on deer and hogs gets consistent praise, and most hunters appreciate that it fits a standard AR lower with only a barrel and magazine swap. The OD Green Cerakote finish tends to be well received among those who want a field-ready look.

Common criticisms center on ammunition availability and cost. .450 Bushmaster is not as widely stocked as more common calibers, and per-round cost is higher, which affects how often people take it to the range. A few users mention the 5-round magazine limit as a practical constraint, though it's a legal requirement in certain hunting jurisdictions. Weight is occasionally noted. At 6.4 lbs it's on par with similar big-bore ARs, but some find it heavier than lighter AR builds they've used before.

Generally recommended for deer and hog hunting, with the caveat that buyers should confirm local ammo availability before committing.
