Built for Big-Bore Confidence

The .450 Bushmaster chambering is designed for decisive performance in a streamlined AR-15 footprint. The 20-inch barrel profiles the cartridge’s strengths—velocity and energy—while maintaining the nimble handling that AR shooters expect. Paired with Bushmaster’s Snake Charmer muzzle brake, recoil is tamed and muzzle jump is mitigated, promoting comfortable shooting sessions and confident second-shot speed.

Free-Float Precision, Modular Control

A true free-float 14" M-LOK handguard lets the barrel resonate freely for consistent accuracy while giving you flexibility to place accessories exactly where you want them. Add a bipod for prone stability, a sling mount for carry comfort, or a white light for low-light control—M-LOK slots keep your setup clean, rigid, and scalable.

Optics-Ready Upper: Your Glass, Your Mission

The flat-top, optics-ready configuration makes it easy to mount a low-power variable optic (LPVO), red dot, or magnified scope suited to your environment. Whether you’re optimizing for close-to-midrange woods hunting or dialing in dope on an open field, the XM-15 E2S platform is ready to match your preferred sighting system.

A2 Stock Ergonomics & Classic Balance

The A2 fixed stock anchors the rifle with a familiar length of pull and stable shoulder interface. It’s a proven geometry that promotes repeatable cheek welds for precise shot placement—especially welcome when running heavier-recoiling big-bore calibers.

Aluminum Magazine Included

Purpose-built for the .450 Bushmaster cartridge, the included aluminum magazine is engineered for reliable feeding under a variety of field conditions. Its durable construction stands up to range use and travel so you can focus on shooting, not gear fuss.
