Great Lakes Firearms GL10 Custom Billet 300 Win Mag 5-Rd Aluminum Magazine - Black

The Great Lakes Firearms GL10 Custom Billet magazine is a factory 5-round aluminum box magazine built specifically for the GL10 LA AR-10 platform long-action rifle chambered in .300 Winchester Magnum. Machined from billet aluminum with a durable black finish, this mag feeds the magnum-length GL10 action and serves as a direct factory replacement or spare for your GL10 build.

Designed as a purpose-built centerfire rifle magazine, the GL10 Custom Billet keeps the overall profile compact for the .300 Win Mag chambering while delivering the positive seating and lockup GL10 owners expect from an OEM GLFA part. Whether you are running a hunting load or working up a precision magnum round, this aluminum 5-rounder is the factory magazine that belongs in your range bag alongside your GL10 LA rifle.
