Black Rain Ordnance Joker Magazine Features The Black Rain Ordnance Joker magazine is built around a sturdy impact resistant polymer body designed as a lighter more durable alternative to the standard USGI aluminum magazine. The laser etched Joker graphics on both sides give the magazine a distinctive custom look while the textured grip surface improves handling during reloads. An anti-tilt super follower keeps the stack aligned so rounds present consistently to the bolt reducing the chance of a feed malfunction. Chambered for 5.56x45 NATO and .223 Remington the 30-round capacity matches standard AR-15/M4/M16 platform magazines for easy compatibility. Inside the polymer body a heavy duty non-memory non-corrosive stainless steel spring maintains consistent feed pressure across repeated loadings without the fatigue that can affect standard spring designs. This spring construction extends the service life of the magazine even under frequent range use and duty carry. Made in the U.S.A. the Black Rain Ordnance Joker magazine suits AR-15 owners who want a reliable spare magazine that stands out from a plain black duplicate. It is a practical upgrade for range bags home defense rifles and competition loadouts alike.
