Description
The ProMag COL19 is a 5-round detachable replacement magazine for the AR-15 platform chambered in .223 Remington / 5.56x45mm NATO. Built around a heat-treated steel body with a blued (oxide) finish, the COL19 is cut to the length of a standard GI 20-round magazine, giving it a familiar profile and proven feeding geometry for range use, training, or use in jurisdictions where reduced magazine capacity is required.
ProMag has long been a go-to source for affordable, rugged aftermarket magazines, and the COL19 carries that reputation forward. The all-steel construction resists deformation under rough handling, and the simple detachable design installs and drops free just like a factory magazine. Whether you need a spare for the range, a low-capacity option for hunting areas with magazine restrictions, or a dedicated training mag, this AR-15 magazine delivers dependable performance at a budget-friendly price point.
