ProMag RM10 Rollermag AR-15 5.56 NATO 10-Round Polymer Magazine

The ProMag RM10 Rollermag is a 10-round polymer magazine for AR-15 pattern rifles, chambered for 223 Remington, 5.56x45mm NATO and 300 Blackout. It is designed for shooters who want reliable, consistent feeding from a lightweight magazine body.

The magazine uses a DuPont Zytel polymer body in black and a Rollerfollower design intended to reduce friction and resist tilting as rounds are fed. It is built with chrome silicon springs. The raw retailer text also describes a rollerfollower anti-tilt feed system and a long-term storage claim, which are not confirmed by the structured specifications and are not repeated here.

Compatibility is with the AR-15 platform. The listed capacity is 10 rounds.
