Bushmaster XM-15 5.56 AR-15 Rifle W/ Fixed Carry Handle -TRADE IN

Note: This is a used firearm and will show signs of wear.

The Bushmaster XM-15 with fixed A2 carry handle upper delivers the classic AR-15 fighting configuration — iron sights from the factory, a proven mil-spec platform, and the familiar M4-pattern polymer handguard — chambered in 5.56 NATO for full compatibility with mil-spec and commercial .223 Remington loads.

The Bushmaster XM-15 is a semi-automatic AR-15 style carbine chambered in 5.56 NATO/.223 Remington, built on forged 7075-T6 aluminum upper and lower receivers to mil-spec standards. This variant features a fixed A2 carry handle upper with integrated rear aperture sight, a standard M4-style oval polymer handguard, and a six-position collapsible stock.

Bushmaster has manufactured the XM-15 platform to mil-spec tolerances since the early era of the commercial AR-15 market, and this configuration reflects the traditional AR-15 fighting carbine setup that defined the platform. The fixed A2 carry handle integrates the rear sight directly into the upper receiver — a fully adjustable mil-spec aperture with elevation and windage corrections — eliminating the need for a separate rear sight and providing a lower-profile, snag-free carry point at the top of the receiver. The front sight post tower and A2 rear aperture together deliver a proven iron sight system that functions in any lighting condition without batteries, electronics, or glass. The standard M4-style oval polymer handguard provides a familiar grip surface and adequate barrel clearance for heat management during sustained fire, while keeping the overall profile slim and the rifle light for extended carry. The mil-spec trigger group delivers consistent pull characteristics across the service life of the rifle. The 5.56 NATO chamber accepts both 5.56 NATO and .223 Remington ammunition without modification, providing flexibility across the widest range of available factory and surplus loads. The six-position collapsible stock allows length-of-pull adjustment for shooters of different builds or for use with body armor and plate carriers.

The 5.56 NATO chamber accepts both NATO and commercial .223 Remington loads without modification.
