ProMag's AR-308 magazine gives .308-pattern rifle owners an affordable way to build up a deep magazine inventory without hunting down expensive factory originals. The body is molded from impact-resistant black polymer with a steel spring and anti-tilt follower, holding 20 rounds of .308 Winchester or 7.62 NATO. It's a sensible choice for range days, truck-gun spares and general practice where you'd rather not beat up your best magazines. The polymer construction keeps weight down compared with steel alternatives and won't rust in storage. Fits standard AR-10 pattern rifles built to SR-25 magazine specification.
