ProMag Rollermag AR-15 5.56 NATO 30-Round Steel Lined Magazine Black

The ProMag Rollermag AR-15 30-round magazine is a semi-automatic rifle magazine for AR-15 platform rifles chambered in 5.56x45mm NATO or 223 Remington. It uses a steel-lined DuPont Zytel polymer body in black and is built to mil-spec fit.

The magazine holds 30 rounds and uses an anti-tilt follower fitted with rollers to reduce friction during feeding. The spring is listed as chrome silicon. The raw retailer text also describes the body as Technapolymer, which conflicts with the DuPont Zytel listing, so the structured material data is used here.

The magazine is listed as made in the USA, with manufacturer number RM-30-LS.
